Description: The 6A7 antibody reacts with mouse, rat, monkey and human Bax (20 kDa). The 6A7 antibody shows no cross-reaction with Bcl-2 or Bcl-xL proteins. Bcl-2, Bax, and Bcl-xL are members of a protein family that regulates apoptosis; while several family members including Bcl-2 and Bcl-xL inhibit apoptosis, overexpression of Bax promotes programmed cell death. A human Bax protein peptide sequence, aa 12-24, was used as immunogen.
