Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to for technical protocols.
  3. 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.
  4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.

Bcl-x is related to the Bcl-2 protein and can function independently of Bcl-2 in regulating apoptosis (programmed cell death). The bcl-x transcript is expressed in a number of tissues, with the highest levels in the lymphoid and central nervous systems. Two distinct cDNA species, bcl-xL and bcl-xS, have been observed and appear to arise from alternate 5' splice sites located within the first coding exon of the bcl-x gene. Bcl-xL is composed of 233 amino acids and is similar in size and structure to Bcl-2. The Bcl-xS polypeptide shows a deletion of 63 amino acids which consist of the region of Bcl-xL with the highest degree of amino acid identity to Bcl-2. Like Bcl-2, Bcl-xL inhibits cell death upon growth factor withdrawal when transfected into an IL-3-dependent cell line. However, Bcl-xS inhibits Bcl-2 mediated cell survival.

Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
