Description: The 2H12 antibody reacts with human, mouse and rat Bcl-X. Bcl-X functions as a central repressor of several apoptotic signals.This antibody reacts with both Bcl-XS (short) and Bcl-XL (long) proteins.
Applications Reported: The 2H12 antibody has been reported for use in immunoblotting (WB).
Applications Tested: The 2H12 antibody has been tested by Western blot analysis of HeLa lysate and can be used at less than 2 µg/mL. It is recommended that the reagent be carefully titrated for optimal performance in the assay of interest.
Purity: Greater than 90%, as determined by SDS-PAGE.
Aggregation: Less than 10%, as determined by HPLC.
Filtration: 0.2 µm post-manufacturing filtered.
Overexpression of Bax accelerates apoptotic death induced by cytokine deprivation in an IL-3-dependent cell line, and Bax also counters the death repressor activity of Bcl-2. Bcl-x, one of several additional proteins with sequence homology to Bcl-2, is expressed as Bcl-xL, a 233 amino acid protein with 43% sequence identity with Bcl-2 that suppresses cell death, and Bcl-xS, a shorter variant that is 178 amino acids in length and lacks a 63 amino acid region (amino acids 126-188) found in Bcl-xL and which functions as a dominant inhibitor of Bcl-2. A further apoptosis-inducing protein, Bad, dimerizes both with Bcl-xL and to a lesser extent with Bcl-2, thus displacing Bax and inducing apoptosis.
