Map, Sequence and MCS
Clone a gene using appropriate restriction sites into the MCS. Protein expressed from this plasmid in E. coli can be purified on a chitin affinity column. The tag can be cleaved on-column with reducing agents such as DTT or MESNA, leaving a C-terminal reactive thioester. Peptides and proteins with N-terminal Cys residues will react with the thioester to form a native peptide bond. This vector is part of the IMPACT-CN kit:
