Bcl-2 (Apoptosis regulator Bcl-2, B Cell CLL/lymphoma-2)

Antibodies / Antibodies-Apoptosis

-20°C

Supplied as a liquid in 10mM PBS, 0.05% BSA, 0.05% sodium azide.

Synthetic peptide corresponding to aa41-54, GAAPAPGIFSSQPG-Cys, from human Bcl-2. Cellular Localization: Outer mitochondrial membranes and endoplasmic reticulum as well as nuclear membranes.

Expression of bcl-2alpha oncoprotein inhibits the programmed cell death (apoptosis). In most follicular lymphomas, neoplastic germinal centers express high levels of bcl-2alpha protein, whereas the normal or hyperplastic germinal centers are negative. Consequently, this antibody is valuable when distinguishing between reactive and neoplastic follicular proliferation in lymph node biopsies. It may also be used in distinguishing between those follicular lymphomas that express bcl-2 protein and the small number in which the neoplastic cells are bcl-2 negative.

Applications: 
Suitable for use in Immunofluorescence, Flow Cytometry, Western Blot, Immunoprecipitation and Immunohistochemistry. Other applications not tested.

Recommended Dilution:
Flow Cytometry: 0.5-1ug/million cells
Immunofluorescence: 0.5-1ug/ml
Western Blot: 0.5-1ug/ml
Immunoprecipitation: 0.5-1ug/500ug protein lysate
Immunohistochemistry (Frozen & Formalin-fixed): 0.5-1ug/ml for 30 minutes at RT. Staining of formalin-fixed tissues is enhanced by boiling tissue sections in 1mM EDTA Buffer, pH 7.5-8.5, for 10-20 min followed by cooling at RT for 20 minutes.
Optimal dilutions to be determined by the researcher.

Positive Control:
Jurkat, K562, HL-60, or HeLa Cells. Tonsil or follicular lymphomas.

Storage and Stability:
May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
