GEL IMAGE!!!

Gel results indicate about a problem. Tomorrow we will use new pMaster from midiprep and new Survivin mCherry from glycerol stock (10ml of LB (+ampicillin) was inoculated).

• The restriction products of uUBB, uMLP were purified using PCR purification kit. Nanodrop concentration results were 21.1ng/μl for uUBB and 35.9ng/μl for uMLP.
• We inoculated 10ml of LB (+ampicillin) with one colony from pMaster+SaCas9 from yesterday.
• We inoculated 10ml of LB (+ampicillin) with one colony from pMaster+Survivin mCherry from 16.08.

19.08.15

In the lab today: Vlad, Shalev

• Nothing grew in LB of pMaster+Survivin mCherry from yesterday.
• LB of pMaster+SaCas9 is OK. Miniprep was performed.

We prepared 1% Agarose gel, and ran Miniprep products.

Gel results indicate that ligation of pMaster+SaCas9 failed.

• We performed midiprep for pMaster and miniprep for Survivin mCherry. Then restrictions of both with SalI, PacI. All restrictions done in incubation for 30 minutes at 37°C. Alkaline phosphatase was added to pMaster.

We run restriction products on the gel prepared earlier today, extracted the appropriate DNA band (according to size) and performed gel extraction protocol.

• Ligations :
• Ligation of pMaster (vector) with Survivin mCherry (insert). (Survivin from today).

Ligation of pMaster (vector) with Survivin mCherry (insert). (Survivin from 16.08).

Ligation of pMaster (vector) with Survivin mCherry (insert). (Survivin from 13.08).

Ligation of pMaster (vector) with uMLP (insert). (uMLP from 18.08).

20.08.15

In the lab today: Vlad, Shalev

• No colonies found on any of the plates from yesterday.
• We think maybe there is a problem with the pMaster. So we prepared 1% Agarose gel, and run ligation products from different days.

GEL IMAGE!!!

We decided to try pMaster from 2 dates: 19.08 and 16.08 for today's ligations:

Ligation of pMaster (vector) with Survivin mCherry (insert). (pMaster from 19.08).

Ligation of pMaster (vector) with Survivin mCherry (insert). (pMaster from 16.08).

Ligation of pMaster (vector) with uUBB (insert). (pMaster from 19.08).

Ligation of pMaster (vector) with uMLP (insert). (pMaster from 16.08).

After ligation, products were transformed into DH5α and seeded on LB agar plates with ampicillin ON.

21.08.15

In the lab today: Shoham, Vlad, Shalev

• No colonies found on any of the plates from yesterday.
• We start working on pRC and pHelper of AAV kit.

22.08.15

In the lab today: Shoham

• We performed midiprep for pRC. Nanodrop concentration results were 3745ng/μl (1.81/2.24).
• We performed midiprep for pHelper. Nanodrop concentration results were 4072ng/μl (1.79/2.17).

23.08.15

In the lab today: Vlad, Shalev

• Since no colonies found on any of the plates in 21.08, we do DNA restrictions again.

Restriction of pMaster, Survivin mCherry with SalI and PacI. Incubation for 30 minutes at 37°C. Alkaline phosphatase was added to pMaster.

We ran restriction products on 1% Agarose gel.

GEL IMAGE!!!

Gel result indicates that restriction didn't work as expected. Maybe PacI enzyme doesn't work as expected - enzyme was replaced and restriction done again. Restriction products were separated on 1% Agarose gel.

GEL IMAGE!!!

• Gel result indicates that pMaster restriction didn't work as expected. Maybe pMaster eppendorf is contaminated. So pMaster from original stock was transformed into DH5α and inserted into 10ml of LB (+ampicillin) ON.
• Survivin mCherry gel results are OK.
• Meanwhile, we decided to try ligation with current pMaster. So both pMaster and Survivin mCherry extracted from gel.
• Since it didn't work so far, we tried to improvise with the ligation protocol. Instead of 50ng of vector, we took 100ng. Instead of 150ng of insert, we took 400ng. So the vector/insert ratio was changed from 1:3 to 1:4.

Ligation of pMaster (vector) with dCas9-vp64 (insert).

Ligation of pMaster (vector) with SaCas9 (insert).

• After ligation, products were transformed into DH5α and seeded on LB agar plates with ampicillin ON. We also made a change in transformation protocol - instead of 10 minutes in ice, we left the DH5α for 40 minutes in the ice.
