Human Bcl-2 (GenBank Accession No. P10415), a.a. 1-211 with C-terminal His-tag, MW = 27 kDa, expressed in an E. coli expression system.
Host cell line: E. coli
Background
Suppresses apoptosis in a variety of cell systems including factor-dependent lymphohematopoietic and neural cells. Regulates cell death by controlling the mitochondrial membrane permeability. Appears to function in a feedback loop system with caspases. Inhibits caspase activity either by preventing the release of cytochrome c from the mitochondria and/or by binding to the apoptosis-activating factor (APAF-1).
Immunogen Region
1-211
Tag
C-terminal His-tag
Formulation
40 mM Tris-HCl, pH 8.0, 110 mM NaCl, 2.2 mM KCl, 3 mM DTT, 20% glycerol, and 200 mM imidazole
Species
Human
Application
Useful for the study of apoptosis, screening inhibitors, and selectivity profiling.
Notes
Following theprotocol for BPS Cat. #50222. Briefly,BCL-2 was combined with BCL-2peptide ligand in TR-FRET assay bufferalong with anti-His Tb donor and dyelabeledacceptor. Varying concentrationsof ABT 199 were added and the reactionwas incubated at room temperature for 2hours followed by fluorescent intensitymeasurements.
Avoid freeze/thaw cycles.
