General description

Amino-terminal FLAG-BAP Fusion Protein is a 467 amino acid N-terminal FLAG fusion protein of E. coli bacterial alkaline phosphatase (BAP) with a calculated molecular mass of 49.3kDa. The N-terminal FLAG-BAP Fusion Protein migrates as a 45−55kDa band by SDS-PAGE depending on electrophoresis conditions. FLAG-BAP Fusion Protein has biotechnological applications and is used in the screening of recombinant fusion proteins.
The Amino-terminal FLAG-BAP Fusion Protein is a control prorein used to confirm the funtional integrity of the anti-FLAG M1 and M2 monoclonal antibodies in applications such as western blotting, immunoprecipitation, ELISA, electron microscopy, and FACS.


Amino-terminal FLAG-BAP Fusion Protein has been used as a standard in enzyme-linked immunosorbent assay (ELISA) for osteopontin quantification and in western blotting based quantification of Flag-Wnt8 and Drosophila melanogaster transcription factor interactome.
