A recombinant fragment (within amino acids 1-100) of human BCL2L1 protein was used as the immunogen for the recombinant Bcl-X antibody.
Recognizes a protein of 27kDa, identified as the Bcl-X protein. This MAb shows no cross-reaction with Bcl-2a or Bax protein. Bcl-X has two isoforms, Bcl-XL (long), a 241-amino acid protein which suppresses cell death. And Bcl-XS (short), a 178-amino acid
