The CD20 antigen is a membrane-embedded, non-glycosylated phosphoprotein, 33-37 kDa. CD20 functions as a Ca2+-permeable cation channel, involved in the regulation of B-cell activation, proliferation and differentiation. CD20 appears on the surface of the pre-B lymphocyte between the time of light chain rearrangement and expression of intact surface immunoglobulin and is lost just before terminal B-cell differentiation into plasma cells. Surface expression of CD20 on activated B cells is approximately 4-fold greater than that found on resting B cells. CD20 is virtually specific for normal B-cells. A weak expression has been demonstrated in a subpopulation of T-cells, but not in any other cell type [NordiQC].
免疫细胞化学
ICC shows positive staining in Ramos cells. Anti-CD20 (Alexa Fluor® 488 Conjugate) antibody was used at 1/200 dilution (Green) and incubated overnight at 4°C. The cells were fixed with 4% PFA and permeabilized with 0.1% PBS-Triton X-100. Nuclei were counterstained with DAPI (Blue).
Negative control: ICC shows negative staining in Jurkat cells. Anti-CD20 (Alexa Fluor® 488 Conjugate) antibody was used at 1/200 dilution and incubated overnight at 4°C. The cells were fixed with 4% PFA and permeabilized with 0.1% PBS-Triton X-100. Nuclei were counterstained with DAPI (Blue).
免疫荧光
IF shows positive staining in paraffin-embedded human tonsil. Anti-CD20 (Alexa Fluor® 488 Conjugate) antibody was used at 1/200 dilution (Green) and incubated overnight at 4°C. Counterstained with DAPI (Blue). Heat mediated antigen retrieval with EDTA buffer pH9.0 was performed before commencing with IF staining protocol.
IF shows positive staining in paraffin-embedded human diffuse large B-cell lymphoma. Anti-CD20 (Alexa Fluor® 488 Conjugate) antibody was used at 1/200 dilution (Green) and incubated overnight at 4°C. Counterstained with DAPI (Blue). Heat mediated antigen retrieval with EDTA buffer pH9.0 was performed before commencing with IF staining protocol.
IF shows positive staining in paraffin-embedded mouse spleen. Anti-CD20 (Alexa Fluor® 488 Conjugate) antibody was used at 1/200 dilution (Green) and incubated overnight at 4°C. Counterstained with DAPI (Blue). Heat mediated antigen retrieval with EDTA buffer pH9.0 was performed before commencing with IF staining protocol.
IF shows positive staining in paraffin-embedded rat spleen. Anti-CD20 (Alexa Fluor® 488 Conjugate) antibody was used at 1/200 dilution (Green) and incubated overnight at 4°C. Counterstained with DAPI (Blue). Heat mediated antigen retrieval with EDTA buffer pH9.0 was performed before commencing with IF staining protocol.
