BD, 551022, BD Pharmingen™ Purified Mouse Anti- Bcl-x

Application: Western blot (Routinely Tested)
Regulatory Status: RUO
RRID: AB_394007
Description: Description Members of the Bcl-2 family play a major role in regulating the response of cells to a wide variety of apoptotic signals. Some Bcl-2 family members like Bcl-2, block apoptosis, whereas others promote apoptosis and inhibit Bcl-2 activity. Bcl-x is a Bcl-2 homologue that has two isoforms, resulting from alternative splicing. Bcl-xL (long) is a 241 amino acid protein (25-29 kDa) that is 47% homologous to Bcl-2 on the amino acid level. Bcl-xS (short) is a 178 amino acid protein (~ 19.5 kDa) lacking a 63 amino acid domain that is well conserved among members of the Bcl-2 protein family. Bcl-xL blocks cell death, whereas Bcl-xS inhibits Bcl-2 and promotes cell death. The 2H12 antibody has been reported to recognize human, mouse and rat Bcl-xL (long) protein. An N-terminal peptide (amino acids 3-14) common to human and mouse Bcl-xL and Bcl-xS (short) proteins was used as the immunogen. Thus the antibody is also predicted to recognize the Bcl-xS protein as the sequence used for the immunogen is common to both Bcl-xL and Bcl-xS proteins. Reports from development, however, have indicated that Bcl-xS has not been observable.
Preparation And Storage: Preparation And Storage Store undiluted at -20°C. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
Recommended Assay Procedures: Recommended Assay Procedures In addition to Jurkat cell lysates,  MOLT-4 (Human T-lymphoblasts; ATCC CRL-1582), K-562 (Human bone marrow myelogenous leukemia; ATCC CCL-243), Hut-78 (Human T lymphoma; ATCC TIB-161), human peripheral blood mononuclear cells (PBMC), rat thymocytes and mouse thymocytes have also been reported to be useful as positive controls.
Product Notices: Product Notices Since applications vary, each investigator should titrate the reagent to obtain optimal results. Source of all serum proteins is from USDA inspected abattoirs located in the United States. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
