Lab Notebook Overview
Week 1: May 2-8
Bacillus
We designed gBlocks for our gene (3α-HSD): one for the original sequence and one Bacillus-optimized.
Active team members this week: Liron, Tal, and Ruth
E.coli
Planned the Gibson reaction for our gBlock of 3α-HSD and the plasmid N155 (from our mentors) containing pT7, RBS and mcherry.
Ordered the gBlock of 3α-HSD, from IDT, which was optimized for E. coli codon usage. We also ordered primers for the Gibson reaction for the gBlock.
Performed reverse PCR to the N155 plasmid and carried out a DPN1 reaction on the product.

Comb
A mechanical engineering student, Michael Yannai, helped me design the first prototype of the comb. We designed it to look like a lice comb with internal channels and thick teeth. The main entrance to the channels is located at the side of the comb.
Active team members this week: Maayan
NADPH
This week we did a lot of research. We found that the 3α-HSD enzyme can use both NADH and NADPH as co-factors for the reduction reaction in order to inactivate DHT to 3α-diol.
NADPH has been found to not only enable the reaction in the direction we want, but also to inhibit the reverse reaction if DHT (Rizner, et al.) Therefore, we have decided to try to overproduce NADPH in a host organism, in order to support the activity of the enzyme.
Active team members this week: Yael and Roni
Week 2: May 9-15
Bacillus
We received the gBlocks and performed PCR. We had some difficulties amplifying the Bacillus-optimized gblock, and since we found out that B.subtilis has no preferred codon usage, we decided to continue only with the gblock of the original sequence.
Active team members this week: Liron, Tal, and Ruth
E.coli
Our gBlock arrived!!!
We performed PCR on the 3α-HSD gBlock with only 10 cycles (as recommended), but received no band in the gel.
We performed PCR on the 3α-HSD gBlock in higher temperatures, but still received no bands in the gel.
Active team members this week: Adi
Modeling
content
Comb
Met with Prof. Hovav Gazit and set a date for printing the comb.
Active team members this week: Maayan
NADPH
We conducted further research about the production of NADPH. We sent e-mails to authors of journal articles to enquire about genes and knockouts associated with NADPH overproduction.
Active team members this week: Yael and Roni
Week 3: May 16-22
Bacillus
We performed a PCR reaction for the mCherry reporter gene from pUG34 plasmid we got from Inbal Vaknin from Prof. Roee Amit’s lab in the Technion and added a RBS sequence with the primers.
We cleaned the product and performed a restriction enzyme reaction with KpnI and HindIII.
Active team members this week: Liron, Tal, and Ruth
E.coli
Performed PCR on the 3α-HSD gBlock in lower temperatures, no bands in the gel.
Active team members this week: Alexey
Modeling
content
Comb
The first prototype of the comb was been printed in Prof. Hovav Gazit's lab with a 3-D printer. Unfortunately, the channels were blocked with ABS from the printer.
Active team members this week: Maayan and Sagi
NADPH
Received replies from various authors. Prof. Toby Fuhrer, from the Institute of Molecular Systems Biology will be sending us an E. Coli MG1655 strain with a knockout of pgi and UdhA genes associated with the consumption of NADPH. Prof. Hanna Engleberg-Kulka’s lab at the Hebrew University of Jerusalem will be sending us a plasmid containing a zwf gene, which codes for the Glucose-6-Phosphate Dehydrogenase enzyme related to the Pentose Phosphate Pathway, in which NADPH is produced.
Active team members this week: Yael and Roni
Week 4: May 23-29
E.coli
Performed PCR to the 3α-HSD gBlock with more cycles and 15°C temperature gradient- no bands in the gel.
Active team members this week: Alexey and Adi
Modeling
content
Comb
We tried to open the channels inside the comb with a water pressure machine in Prof. Hovav Gazit's lab and mechanically with needle. Our attempts were unsuccessful.
Active team members this week: Maayan and Sagi
NADPH
We received the knockout strain from Prof. Fuhrer! We prepared glycerol stock and competent cells of the strain for further use.
Planned the PCR and ordered primers for the zwf gene containing the sequence for cutting sites for SpeI and XbaI to make ligation with biobricks simple.
Active team members this week: Yael and Roni
Week 5: May 30-June 5
Bacillus
We met with Shira Omer from Avigdor Eldar’s lab from Tel Aviv University and Prof. Ilana Kolodkin from Weizmann Institute. They both recommended working with pDR111 plasmid (a shuttle vector which integrates into the Bacillus genome).
Active team members this week: Liron, Adi, Yael, and Ruth
E.coli
We ordered new primers for the 3αHSD gBlock.
PCR to the 3α-HSD gBlock with new primers and 15°C temperature gradient. We saw weak bands in the gel, but found no DNA after cleaning.
Active team members this week: Alexey and Adi
Modeling
content
Comb
We designed a second prototype. We changed the location of the main entrance hole to the center, top of the comb, to try to enable us to open the channels, mechanically, more easily .
Active team members this week: Maayan and Sagi
NADPH
We are still waiting to receive the plasmid containing the zwf gene. Apparently there are delays in the postal service. Since we suspect that the DNA will break down, we have hired a messenger service to bring it to us early next week.
Planned activity verification experiments for when we have our clones. We will do preliminary experiments using fluorescence, which will indicate total NADPH and NADH levels, and then use the Biovision NADPH/NADP+ Assay kit to verify our results.
Active team members this week: Yael and Roni
Week 6: June 6-12
Bacillus
We checked the plasmids we got from Tel Aviv University and Weizmann Institute by sending for sequencing.
Active team members this week: Liron, Tal, and Ruth
E.coli
We performed a PCR reaction again with the new primers. We saw no bands in the gel.
We planned a new strategy for cloning using restriction enzymes, with BBa_K784023 in pSB1C3 (from iGEM12_Technion) as the backbone.

Comb
We printed the second prototype of the comb. The flow that came out of the teeth of the comb was not simultaneous.

NADPH
We received the plasmid carrying the zwf gene and did PCR to enhance the gene. We cut biobrick BBa_K525998- pSB1C3 with a pT7 promoter and RBS, with SpeI and ligated with our gene.
Transformation of the biobrick into Top10.
Colony PCR to the colonies showed three positive colonies. We sent one for sequencing.
Active team members this week: Yael and Roni
Week 7: June 13-19
Bacillus
We designed primers for the 3a-HSD gBlock and mCherry, containing the sequenced of the new restriction enzymes (SalI and NheI).

E.coli
Made starters from Top10 with BBa_K784023 from glycerol stock, and the performed a miniprep for the BBa_K784023. The DNA concentrations were low, so we repeated the miniprep. After receiving a satisfactory concentration, we cut the plasmid with SpeI and XbaI and performed a CIP reaction.
Ordered new primers for both Gibson and restriction enzymes cloning and performed PCR to the 3α-HSD gBlock with all the new primers. We saw a band in the negative control.

NADPH
The sequencing results for the gene on the pSB1C3 came out positive!! We transformed the plasmid into E. Coli BL21 and the E. Coli MG1655 knockout. Unfortunately no colonies were formed on the LB and agar plates, so we repeated the transformation, but to no avail.
