Planing cooperation -> Fusion of AID without NES with TAL-Protein, primer design

Investigators: Chris, Rico,

AID will be fused to the TAL-protein (N--TAL-AID--C) with BpiI.We will get the fusion protein in an eukaryotic expression-vektor (with CMV promoter or hopefully a weaker one, depending on Team-Freiburg).

The 14 bp sequence for the TAL-protein has to have the following properties: (done by Antibody team)

5' positon 0- must be T,
positon 1- no T ,
Position 2- no A,
Position 13- no G, position 14- must be G

There are two of these sequences in the VH-region of the sc-FV-anti EGFR 425 but not in the direct neighborhood of CDR3.
