Background
The bcl-2 antibody is suitable for the detection of this oncoprotein in normal and abnormal tissues. In normal lymphoidal tissue the antibody reacts with B lymphocytes in the mantle zone, whereas in the germinal centre very few cells are stained. In follicular lymphoma bcl-2 is over-expressed and the staining pattern may be used for differentiation from follicular hyperplasia, which are almost bcl-2 negative. Bcl-2 oncoprotein is a protein, which is localized on the inner membrane of mitochondria and on the endoplasmatic reticulum. It is an inhibitor of apoptosis. In the majority of follicular lymphoma translocation of the bcl-2 occurs, followed by deregulation of protein synthesis. Human bcl-2 oncoprotein .

Positive Control
Tonsil

Pre-Treatment
Heat pre-treatment of formalin-fixed tissue with Unmasking Fluid C or G (Art. No. DE000 and DE007)

Immunogen
Synthetic peptide corresponding to human bcl-2 molecule aa 41-54 (GAAPAPGIFSSQPG-Cys)

Working Concentration
(liquid conc.) 1:100-1:200

Incubation Time
60 min at RT

Secondary Reagents
We recommend the use of BIOLOGO's Universal Staining System DAB (Art. No. DA005) or AEC (Art.-No. AE005).

Caution
*These antibodies are intended for in vitro research use only. They must not be used for clinical diagnostics and not for in vivo experiments in humans or animals. ** The preservative sodium azide is known to be poisonous and potentially hazardous to health. It should be handled only by trained staff. Despite of the product's low azide concentration it must be handled with care. Dispose according to regional rules!
