Experiments:
Mycosporine transformation into HB101 THIS AFTERNOON AT BIOCURIOUS, starting 1pm
UV spectrum of crude mycosporine methanol extract Here's two protocols for extraction of MAAs from cyanobacteria for spectroscopic analysis.
As you can see the first one is very simple: extract in 100% methanol in the fridge overnight, centrifuge, and take the supernatant: https://www.researchgate.net/publication/263709935_Biochemical_characterization_of_sunscreening_mycosporine-like_amino_acids_from_two_Nostoc_species_inhabiting_diverse_habitats Cyanobacterial cells were harvested by centrifugation, and MAAs were extracted in 2 mL of 100% high-performance liquid chromatography (HPLC) grade methanol overnight at 4 °C. The methanol extracts were centrifuged at 10,000 rpm for 10 min, and the supernatant was subjected to spectroscopic analysis between 250- and 700-nm wavelengths, using a double-beam spectrophotometer (UV-Vis 2900, Hitachi, Japan). http://maxwellsci.com/print/crjbs/v3-165-171.pdf
Extraction of 10 mg of dried Aulosira fertilissima in 2 mL 20% Methanol(gradient grade) at 45ºC for 2h . Centrifugation if necessary (10 min 10000 U). 1.5 mL of the supernatant was lyophilised. 2 mL 100 % Methanol was redissolved in the residue further vortexing followed by centrifugation was done. 1.5 mL of the supernatant was evaporated at 45ºC. 1.5 mL H2O was redissolving in the residue, again vortexing and centrifugation was done. Spectroscopic analysis of the supernatant was taken from 200 to 750 nm.
Mycosporine like amino acid (MAAs) (Garcia pichelz et al., 1993)
Step 1. Took 10 mg fresh biomass and were suspended in 20 ml of methanol (20%) and homogenized.
Step2. Covered all the test tubes with aluminium foil and were kept at 45℃ in water bath for 2hrs.
Step3. Centrifuged and filtered the supernatant through whatman filter paper (No.1).
Step4. The absorbance of filtrate were measured spectrophotometrically at many wavelengths (310, 320, 330, 332, 334 and 260).
E. coli cells may be even easier to extract, because cyanobacteria tend to have a stronger cell wall Directed Evolution Round 1?
Patrik will start writing up a protocol
Everybody who has done research on Directed Evolution should help out digging up published protocols.
4. Domestication of gene clusters into IGEM plasmid restriction digest and ligation reaction (Tuesday or Wednesday)
We need Pstl; did we get that in the biobrick cloning kit from NEB?
Total Participation in iGEM:

CCL: Kye, Megan, Patrik, Patrick, Tom, Maureen
ZOOM: Advait, Adarsh, Shreya, Rikke, David, Victoria


UV Hardware:
Drops in the 340nm and 390nm range according to spectra
Experiments:
Rikke starting another kill curve experiment at 1pm at CCL
Jay: transformation in mutagenic strain successful; nothing grew in HB101 (including pGLO positive control).
Need to start doing experiments collecting UV absorption spectrum:
- Measure UV absorption spectrum of TSB (tryptic soy broth). As you heard from Rikke, there seems to be an issue with fluorescence and/or UVabsorption in the medium we've been using for the kill curve experiments.
- Measure E. coli UV absorption spectrum, with and without the pGlo plasmid. (a) in whole cell suspension (b) in cell lysate, (c) in crude protein extract. If we hope to be able to detect a change in UV absorption spectrum in GFP, how should we best measure the spectrum?
- Once we have a mycosporine producing strain, we'll need some way to measure its spectrum as well. Eventually, we'd like to separate the MAAs by HPLC, but just like with the GFP, we could generate a spectrum for a crude extract as well. Here's a few protocols for extracting the MAA-containing fraction with methanol:
https://www.researchgate.net/publication/263709935_Biochemical_characterization_of_sunscreening_mycosporine-like_amino_acids_from_two_Nostoc_species_inhabiting_diverse_habitats
Cyanobacterial cells were harvested by centrifugation, and MAAs were extracted in 2 mL of 100% high-performance liquid chromatography (HPLC) grade methanol overnight at 4 °C. The methanol extracts were centrifuged at 10,000 rpm for 10 min, and the supernatant was subjected to spectroscopic analysis between 250- and 700-nm wavelengths, using a double-beam spectrophotometer (UV-Vis 2900, Hitachi, Japan).
IDT Order:
Need to finalize gene order for Anabaena gene cluster - see https://docs.google.com/document/d/1AVc2TPD71psi-JXjWkUTxp79HHXIEM2vP6k7G7RxbWE/edit?usp=sharing
Jay and Patrik will coordinate on finalizing sequence; can also run by Eric Harness and Wayne
Survey:
https://docs.google.com/forms/d/19URbYIXXwWi9Hv4B7BM6-iEntHuiCIOcK3TGyA39sjI/viewform?usp=send_form are you concerned about effect of sunscreens on your own health on the environment?
difference between UVA, UVB environmental issues are mainly on coral reefs, not coastal environment. and mostly due to other compounds than PABA, TiO2 would you wear sunscreen more if there were a more natural alternative?
Indiegogo Campaign:
Let’s put the fundraiser under CCL
Anyone who wants to work on video can do so.

CCL: Rikke, Kye, Sean
Zoom: David, Adarsh, Victoria, David M.
UV Hardware
Leave as is but UV exposure is not killing bacteria even at 1 hour of exposure, going to try moving closer to lights, right now we are at 8”
Problem with kill curve experiment: Some plates with high UV exposure have more growth than plate exposed to lower amounts of UV. In addition, GFP expression across plates are inconsistent.
potential hypotheses:
UV light is not close enough to kill majority of bacteria.
Bacteria is under stress due to UV irradiation and does not use pGLO plasmid as it doesn’t seem to provide benefit. Note that we are irradiating bacteria with a wide UV spectrum while GFP only absorbs a fraction of it. The TSB media partially absorbs UV light, sheltering bacteria.
Need to get anabana transformed into ecoli onto plate and to CCL
Jay will send out operan again form addgene

At BioC today will miniprep out 5 of the plasmids from addgene today, wont do transformation today (need to get competent cells ready)
And then bring to CCL for kill curve checks
Assume we will do transformations at BioC on Tuesday @ approx 5:30pm to start will take about 3 hours
Patrik start cultures on monday and wednesday and experiments on tuesday and thrusday need to schedule someone to do cell counting within 24 not 48 hours afterwards at CCL

Genes
8/21/15 Update from Jay (sorry can’t make today’s meeting)
The seven AddGene plasmids arrived. I streaked two sets of plates, one for CCL and one for BioCurious. FYI: Addgene used the Top10 E. coli cell line for delivering these plasmids. They are all Kanamycin resistant for selection. I will grow up some liquid cultures Saturday night and will be doing minipreps of the plasmids on Sunday afternoon starting around 3PM. Anyone interested in joining this miniprep festival is welcome!!
I’m in progress designing a GFP-UV gene with His-tag and flanking sequences in the Bio Brick format. As soon as the design is complete and checked we can order from IDT. Anyone interested in helping out on this is certainly welcome. Email me.
Link to Genome Compiler: https://igem.genomecompiler.com/igem_app
All: what else are we ordering from IDT, and when?
Has anyone looked at Jay’s gene cluster construct? Have someone else review
Need to order GFP with histags - Jay will design today in genome compiler folder

Experiments update
See http://bayareaigem.herokuapp.com/index.php?title=Notebook
pGLO transformation at BioCurious (Jay)
The transformation we did on Saturday was successful. We got some transformants on plates 1B, 3B and 2B expressing GFP. I attached images showing all the plates and the GFP glowing under UV (let me know if you need a higher res image). Below is a table of the plate by plate outcomes. We used pGLO plasmids from different sources and some were over a year old so we expected that not all would successfully transform. Thanks to everyone who helped out on Saturday!!
I'll streak an HB101/pGLO plate for CCL. I plan to do a miniprep to purify the pGLO plasmid on Thursday night starting around 7pm if anyone wants to participate. Patrik will be at Biocurious on Thursday night and he can pick up a plate with the transformed HB101 and some plasmid to take back to CCL.
Plate Observation
1 Lawn LA plate no ARA
1B > 20 colonies expressing GFP
2 No growth
2B > 100 colonies expressing GFP
3 ~ 6 colonies - no GFP (did not glow under UV)
3B > 20 colonies expressing GFP
4A No growth
4B Lawn LA plate No ARA
5A No growth
5B No growth
6A No growth
6B No growth
7 No growth

UV sources
See Notes on UV Spectra - all the hardware is documented there
UV kill curve experiments at CCL (Rikke)
Need to normalize bacterial cultures - need to get spectrophotometer online to calculate cell count based on optical density (OD)
Use drop spot plate method for plate counts - saves a lot on plates
Use 96 well plates and multipipetters to do dilutions
Genes
Jay found the Anabaena genes available on plasmids at Addgene - $65 each!
http://www.addgene.org/Christopher_T_Walsh/
Let’s order what we already know we want to get from IDT asap. No need to order everything at once.
codon optimized Anabaena genes (with separate promoters / in separate biobricks?)
Nostoc final enzyme
GFPuv with strong promoter, strong RBS, transcriptional terminator
Need to decide which exact E.coli strain to use with RCA (especially whether or not it should be a RecA / DNA repair mutant!)

Attendees:
BioCurious: Eric H., Maria T. Chavez, Patrik, Eric A, Adarash, James, Rikke, Victoria, Dmitry, Jay, Erik I, Greg, Shreya, Michael, Samera, David, Meekakshi, Johan
Eric’s talk on RCA/RCR - Rolling circle amplification, Rolling circle replication
A way for viruses to replicate their DNA, a compact way to replicate their dna needing only 1 strand of DNA. Uses enzyme phi 29. A way to produce lots of DNA at a low temperature.
Need a circle, need an initiation point (a single stranded circle), 529 will initiate this at the lesion in a double stranded DNA. Phi 29 has a fidelity for doing this that is unreplicated so far from bascillius setellus (???)
RCA is not old technology, it was developed to make copies, for Sanger sequencing. To make a lot of copies of something that is a replication. Make a copy of a whole circle, strand replace and start again making a new circle of DNA. Pic of process - https://en.wikipedia.org/wiki/Rolling_circle_replication.
For our process is to NOT use phi 29 to introduce mutagenesis.
DNB is a DNA nanoball.
Eric today took M13 and put a nick in it to use it today. MB-BSM1 is an asymmetric cutting enzyme and will make a nick in the DNA either top strand (MB is the bottom strand).
Eric will post Protocol used for tonight.

we have various UV illuminators (320nm, 365nm) - copy out some model numbers, and look up spectrum
Stratagene crosslinker
More research on killing E. coli with UVA, UVB, sunlight - what doses at what wavelengths Rikke, Patrik
UV Sources:
At Biocurious: “Strategene crosslinker” - has replaceable / swappable UV bulbs, so will need to know what type of bulb is in there to determine radiation specs
Actual crosslinking is usually done with a very short-wave, very narrow-band UVC bulb (254nm), which would not be suitable for our purposes
Manual says it also has 302nm Midrange (UVB) bulbs (# 34-0042-01) and 365 nm Longwave (UVA) bulbs (# 34-0006-01),
