Background
CD5 is a cluster of differentiation expressed on the surface of T cells (various species) and in a subset of murine B cells known as B-1a. CD5 serves to mitigate activating signals from the BCR so that the B-1 cells can only be activated by very strong stimuli (such as bacterial proteins) and not by normal tissue proteins. CD5 was used as a T-cell marker until monoclonal antibodies against CD3 were developed. There is no confirmed ligand for CD5 but there is evidence that CD72, a C-type lectin, may be a ligand or that CD5 may be homophilic, binding CD5 on the surface of other cells.

Immunofluorescence
IF shows positive staining in paraffin-embedded human tonsil. Anti-CD5 (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.
