  • Since we can't do ligation with current products of restriction, we tried ligation of yesterday's product again:
  • Ligation of pAAV (vector) with AF (insert).
  • Ligation of pMaster (vector) with uMLP (insert).
  • Ligation of pMaster (vector) with uUBB (insert)
  • Ligation of pMaster (vector) with dCas9-vp64 (insert).
  • Ligation of pMaster (vector) with SaCas9 (insert).
  • Ligation of pMaster (vector) with Survivin mCherry (insert).
  • After ligation, products were transformed into DH5α and seeded on LB agar plates with ampicillin ON.

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).

In the lab today: Shoham, Vlad, Shalev

  • No colonies found on any of the plates from yesterday.

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.

24.08.15

In the lab today: Shoham, Vlad, Shalev

  • We performed miniprep for pMaster from yesterday (from stock). Nanodrop concentration result was 233ng/μl.

    Ligation of yesterday's pMaster (vector) with uMLP (insert).

    After ligation, products were transformed into DH5α and seeded on LB agar plates with ampicillin ON. Like yesterday, for one of pMaster+ Survivin mCherry ligations we changed the protocol - instead of 10 minutes in ice, we left the DH5α for 40 minutes in the ice.

  • AAV plasmids arrived from cloning: Htert+SaCas9, Htert+dCas9-vp64, MLPE, SMLP, SUBB.
