Anti-Protein S Monoclonal Antibody

Anti-Protein S Monoclonal Antibody can be used for detection of ProS2-fused proteins expressed from the cold shock expression vector pCold ProS2 DNA (Cat. #3371). ProS2 is an approximately 23 kDa soluble tandem-dimer peptide tag derived from the N-terminal domain of Protein S, a soluble protein that originates from the myxobacterium species Myxococcus xanthus.
