      Purified Mouse Anti-Human Bcl-2 w/Control

      BD Pharmingen™ Purified Mouse Anti-Human Bcl-2 w/Control

      (RUO)
      Purified Mouse Anti-Human Bcl-2 w/Control
      Profile of permeabilized lymphocytes analyzed on a FACScan (BDIS, San Jose, CA) (left panel). Cells were stained with anti-human Bcl-2 (clone Bcl-2/100) or a mouse IgG1 isotype (negative) control followed by FITC-conjugated second step.
      Purified Mouse Anti-Human Bcl-2 w/Control
      Western blot analysis of Bcl-2 (right panel). Lysate from Jurkat cells was probed with clone Bcl-2/100 at concentrations of 1.0 (lane 1), 0.5 (lane 2), and 0.125 µg/ml (lane 3). Bcl-2 is identified as a band of ~26 kDa.
      Purified Mouse Anti-Human Bcl-2 w/Control
      Formalin-fixed, paraffin-embedded tissue sections stained for Bcl-2 expression using clone Bcl-2/100 and the SA-HRP method. (Left panel) Normal tonsil. (Right panel) Follicular lymphoma. In normal tonsil the mantle zone and intrafollicular region are stained; only occasional Bcl-2 positive cells are seen in the germinal center. In follicular lymphoma, tumor follicles are Bcl-2 positive.

      Description

      Bcl-2 is considered to be novel among proto-oncogenes because it blocks apoptosis (programmed cell death) in many cell types. Apoptosis is an active form of cellular suicide that typically requires new RNA and protein synthesis and is associated with distinct morphological changes including cell shrinkage, cytoplasm membrane blebbing, nuclear fragmentation and DNA degradation. Because Bcl-2 blocks apoptosis it may contribute to tumorigenisis by prolonging cell survival, rather than by accelerating the rate of cell proliferation. Human Bcl-2 protein migrates at a molecular weight of ~26 kDa by SDS-PAGE. Bcl-2/100 recognizes a 26 kDa band representing human Bcl-2. Additional minor bands at 27-31 kDa and 18-21 kDa may also be visualized. The 27-31 kDa upper band may represent a larger isoform, whereas the 18-21 kDa lower band may be an internal translation or proteolytic product, therefore, a synthetic peptide corresponding to amino acids 41-54 (GAAPAPGIFSSQPG) of human Bcl-2 was used as immunogen. This peptide sequence is not conserved between human and mouse. Bcl-2/100 does not cross-react with mouse Bcl-2. For detection of mouse Bcl-2 refer to clone 3F11 (Cat. No. 554218), polyclonal rabbit anti-rat/mouse Bcl-2 antiserum (Cat. No. 554087), and polyclonal rabbit anti-mouse Bcl-2 antiserum (Cat. No. 554279).

      Preparation And Storage

      The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. Store undiluted at -20°C.

      Recommended Assay Procedures

      Western Blot: Jurkat control lysate [50 µg (1 µg/µl)] is provided as a western blot positive control (Comp. No. 51-16526N; Store lysate at -20°C). Additional control lysate (Cat. No. 611451) is sold separately.

      IHC: For paraffin-embedded sections, tissues should be fixed in either Bouin's fixative or formalin.

      For immunofluorescent staining and flow cytometry,  our directly conjugated formats are recommended, Cat. No. 556535 and 556357.
