AID in Potsdam Standard

AID is known to be responsible for somatic hypermutation and the class-switch recombination of immunoglobulin in B cells. This enzyme of 28 kDa originally occurs in B cells but does also show activity after transfection into CHO cells. AID induces the deamination of cytidine to uridine at actively transcribed single strand DNA. The replacement of cytidine by uridine leads to a mismatch during DNA replication and integrates a single base substitution predominantly in the immunoglobulin genes.
To generate this part, we used the Potsdam Standard for cloning the AID into the Potsdam Standard Backbone. Here, we tested four different ligation conditions: 1. with electrophoretic unpurified, digested Potsdam Standard backbone with and without ligase and 2. with electrophoretic purified digested Potsdam Standard backbone with and without ligase. The results are summarized in fig. 1.
