Bcl-x is a member of the Bcl-2 family of proteins that regulates outer mitochondrial membrane permeability. Alternative splicing results in two distinct Bcl-x isoforms. Bcl-xL (long) is an anti-apoptotic protein that prevents release of Cytochromec from the mitochondrial intermembrane space into the cytosol. Bcl-xs (short) is a pro-apoptotic member that can initiate programmed cell death.

Specificity
Recognizes a protein of 27kDa, identified as the Bcl-X protein. This monoclonal antibody shows no cross-reaction with Bcl-2 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 protein lacking a 63 amino acid domain which functions as a dominant inhibitor of Bcl-2. This monoclonal antibody reacts with both Bcl-XS and Bcl-XL proteins.

Application
Recommended Usage
Flow Cytometry
1-2 ug/million cells
Immunocytochemistry/ Immunofluorescence
1-2 ug/ml
Immunohistochemistry-Paraffin
1-2 ug/ml
Western Blot
1-2 ug/ml
Application Notes
Immunohistochemistry (Formalin-fixed): 1-2ug/ml for 30 minutes at RT. Staining of formalin-fixed tissues requires heating tissue sections in 10mM Tris buffer with 1mM EDTA, pH 9.0, for 45 min at 95C followed by cooling at RT for 20 minutes.
Optimal dilution for a specific application should be determined.
