Also, control plasmid was run with them and a volume of 15 microlitres was used for transformation, although in protocol provided it is mentioned that only 1micro is needed with supercompetent cells. --> 24hrs later, no colonies are yet present on any of the plates, including the control!

9-16-2009

Biobricking

• CMV - cherry
• CMV - myrcherry
• CMV - kzkcherry
• CMV - eGFP
• CMV - kzkeGFP

subm(er)izing:

• All transformations worked and test digests show that we have:

-Intron

-Jet (S1)

-PolyA tail

-->problem: No sequencing primers available for verification yet, so nothing is assured, but cloning will be resumed with available components.

-Nevertheless, used one of the Jet submission plasmids (Jet1) to do the subcloning of a CMV core promoter with the Jet proximal.

-->digested S1 with hindIII and NheI

Cloning of sequencing primers into p31:

-Ligation into p31 didn't work. No more PCR product is left, so ran PCR again.-->worked.

-In the meantime, ligation was tried again with different molar ratios (1:1, 1:3, 3:1) --> no colonies grew.

Mutagenesis PCR:

-Didn't work :(((

9-22-09

Biobricking Preps of the Ligations

Subm(er)izing:

-Ligated CMV-core (from p48) into digested S1.

-->Problem: used the undigested plasmid instead of digested plasmid, so this failed.

Cloning of sequencing primers into P31:

-Transformed ligations from day before --> didn't work

- Digested the new PCR product with NsiI and MfeI using two protocols for the sequential digest.

I:

Digest with Mfe-I HF in buffer 3 (low salt) then add NsiI in buffer 4.

II:

Digest with Mfe-I, PCR purify and then redigest in NsiI.

-Ligated new PCR digest into the old p31.

• cmv-myrpalm + kzkeGFP-PolyA
• cmv-myrpalm + myrcherry-PolyA

Mutagenesis PCR

Minipreped picked colonies for p41 (2x). Only one of which grew in LB. Sent for sequencing.

Sequencing primers in p31: -minipreped picked colonies.

-transformed new ligations.

Subm(er)izing:

-Minipreped picked clones for S21(Jet core and proximal)

-Transformed S2 ligations (CMV core and Jet proximal)

!!!Problem: Labels on samples got wiped off during minipreping.

Digested all samples with 3 different protocols:

1) EcoRI and PstI: S1 should give an insert of ~200 bps. P41 muta shouldn't be cut.

2) Hind III and NotI: S1 should be digested and so should p41 muta (difference in lenght of backbone and p41 should have a ~500 bp insert)

3)Hind III (same for p31-neu): same as Hind III and NotI but no insert should be detectable. (only linearised fragments of different lenghts).

--> Gel showed abnormal mixture of multiple fragments for all digests. Unassociatable with any of the expected plasmids. possible that plates were left too long in incubator and other bacteria grew on plates.

9-26-09

Miniprep and testdigest of yesterdays Transformations

Transformation of yesterdays Ligations

Subm(er)izing:

-Made minipreps of: -p37and p34 amplicons in p49 for minipreps of enough DNA to be digested and used for cloning into submission.

--> test digest with EcoRI and PstI shows that the plasmids have not the expected insert. Possible that the plates were too overcrowded and the picked colonies were ones that were negative.

-Made minipreps of: S2 bacterial suspensions.

--> test digest with Hind and PstI shows that the colonies lack the correct insert.

Sequencing primers for p31:

-Made minipreps of picked colonies.

--> Test digest with EcoRI and PstI shows that they have the correct insert. 4 samples were picked for sequencing.

-Digested Corri's natural promoters with EcoRI and PstI.

--> Gel extracted the parts.
