General description

Monoclonal ANTI-FLAG® M2-Alkaline Phosphatase is a purified IgG 1 mouse antibody covalently conjugated to calf intestinal alkaline phosphatase (AP). The antibody conjugate binds to FLAG® fusion proteins and will recognize the FLAG® epitope at any position in the fusion protein (N-terminal, Met-N-terminal, C-terminal or internal FLAG® peptides).


Monoclonal ANTI-FLAG® M2-Alkaline Phosphatase antibody produced in mouse has been used:
  • in direct tissue blot immunoassay of sweet orange petioles samples
  • in screening internalization of delta opioid receptor
  • for screening cell-free protein expression using ELISA

Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.
