Background
CD45 is a type I transmembrane protein that is present in various isoforms on all differentiated hematopoietic cells (except erythrocytes and plasma cells). CD45 has been shown to be an essential regulator of T- and B-cell antigen receptor signaling. It functions through either direct interaction with components of the antigen receptor complexes via its extracellular domain (a form of co-stimulation), or by activating various Src family kinases required for the antigen receptor signaling via its cytoplasmic domain. CD45 also suppresses JAK kinases, and so functions as a negative regulator of cytokine receptor signaling.

Immunocytochemistry
Negative control: ICC shows negative staining in MCF7 cells. Anti-CD45 (Alexa Fluor® 594 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).
Immunofluorescence
IF shows positive staining in paraffin-embedded human colon. Anti-CD45 (Alexa Fluor® 594 Conjugate) antibody was used at 1/200 dilution (red) 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 spleen. Anti-CD45 (Alexa Fluor® 594 Conjugate) antibody was used at 1/200 dilution (red) 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 tonsil. Anti-CD45 (Alexa Fluor® 594 Conjugate) antibody was used at 1/200 dilution (red) 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.
