General description

Purified mouse monoclonal antibody generated by immunizing BALB/c mice with the specified immunogen and fusing splenocytes with SP2/0-AG14 plasmacytoma cells (see application references). Recognizes the ~24-26 kDa bcl-2 protein.
Recognizes the ~24-26 kDa Bcl-2 protein in MCF-7 cells, tonsil, and lymph node tissue.
The bcl-2 proto-oncogene is encoded by a gene 230 kb in size that gives rise to a ~24-26 kDa protein which has been localized to the mitochondrial membrane. Although some data exists for implicating bcl-2 as a novel GTP binding protein, the major function of bcl-2 appears to be an inhibitor of apoptosis or "programmed cell death". It has now been well documented that bcl-2 becomes deregulated in tumor cells as a result of translocation into the immunoglobulin heavy-chain locus and is therefore constitutively activated in B cell malignancies (i.e. follicular lymphoma and chronic lymphocytic leukemia). In addition, bcl-2 has also been shown to protect mammalian cells from sodium azide, colchicine, DNA, RNA, and protein-synthesis inhibitors, as well as steroids, heat shock and irradiation.

Immunogen

a synthetic peptide (GAAPAPGIFSSQPG) corresponding to amino acids 41-54 of human Bcl-2

Application

Frozen Sections (1-5 μg/ml)
Immunoblotting (1-5 μg/ml)
Paraffin Sections (1-10 μg/ml, see comments)

Physical form

In 50 mM sodium phosphate buffer, 0.2% gelatin, pH 7.5.

Analysis Note

Positive Control
MCF7 cells or tonsil or lymph node tissue

Other Notes

Generally, no pre-treatment of paraffin sections is needed, but treating with heat may improve staining in some tissues. Antibody should be titrated for optimal results in individual sample types.

The goal of this study was to determine whether it will be feasible to study the expression of a large, human gene, such as the BCL2 proto-oncogene, by DNA transfection. The BCL2 proto-oncogene is 230 kb in size and is

The BCL2 (B cell lymphoma/leukemia-2) and C-HA-RAS oncogenes encode membrane-associated proteins of 26 and 21 kilodaltons, respectively. Although RAS proteins have long been known for their ability to bind and hydrolyze GTP, recent investigations suggest that BCL2 encodes a novel

Cell death is a normal physiological process. Morphological studies have shown that cells that die by physiological mechanisms often undergo characteristic changes termed "apoptosis" or "programmed cell death." Recent work has begun to unravel the molecular mechanisms of these deaths

The BCL2 protooncogene encodes an inner mitochondrial membrane protein that blocks programmed cell death. BCL2 was isolated from the chromosomal breakpoint of follicular B-cell lymphoma. Transgenic mice that overexpress BCL2 display extended survival of resting B cells. In this study
