SAP dephosphorylation

18 April 2013 - 04:30 AM

Hi all,

Wondering at what stage SAP is best used, following gel purification of the vector cut by a single enzyme, I have done it right after digestion with BamHI and have been having trouble getting a ligated product with my insert, guessing that Im getting recircularization of the vector?
Thanks.

Determining in frame in modified vector

12 April 2013 - 06:02 AM

Hi, if I add novel restriction sites to a vector backbone to accept an insert, what is the best way to assess if my vector modification has kept everything in frame? Thanks.

Deleting restriction enzyme sites

12 April 2013 - 04:46 AM

Hi,

What is the currently best accepted method to do this in a plasmid? Need to delete a site in the middle of my insert that is crucial for ligating that insert into the vector. Thanks!

Creating primers to add restriction sites to vector backbone

11 April 2013 - 05:26 PM

Hi all,

I need to add restriction sites to where a single BamHI site sits on my backbone to be able to ligate an insert into that spot, no MCS on this plasmid. I have not done this and am wondering if anyone has experience modifying the recipient vector with additional sites? Any rules/strategies for primer design to amplify my 8kb vector by PCR and add two unique sites? Thanks.

Mouse genotyping issues

13 March 2013 - 02:59 AM

Hi all,

Wondering if you can help. I am having some issues with genotyping, using a traditional KO LacZ gene targeting strain - and although I get exactly the predicted bands for LacZ, WT and both for het that the original paper predicted I am at times still seeing protein and transcripts of the knocked out protein in the tissue of a KO mouse. I am wondering if years of inbreeding may have introduced some mutation, not really sure how to test this. Any ideas would really help, thanks!
