Sortase 2A.9 is an engineered variant of the wild-type sortase from Staphylococcus aureus that is significantly more active than the wild-type sortase for site-specific labeling of antibodies or proteins containing an LAXTG recognition sequence (where X is any amino acid). Directly conjugate fluorophores, enzymes (HRP, AP), biotin, peptides, DNA, carbohydrates or other labels to the terminal end of the heavy chain to ensure the antigen binding site remains available for target recognition.
