Western blot analysis of CD21 expression in Raji (A), KB (B), NIH3T3 (C) whole cell lysates. (Predicted band size: 112 kD; Observed band size: 115 kD)

Immunohistochemical analysis of CD21 staining in human tonsil formalin fixed paraffin embedded tissue section. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0). The section was then incubated with the antibody at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
