|Detection of CD5 in Mouse Splenocytes by Flow Cytometry. Mouse splenocytes were stained with Rat Anti-Mouse CD3 PE‑conjugated Monoclonal Antibody (Catalog # FAB4841P) and either (A) Rat Anti-Mouse CD5 APC‑conjugated Monoclonal Antibody (Catalog # FAB115A) or (B) Rat IgG2A Allophycocyanin Isotype Control (Catalog # IC006A).

Mouse CD5 has been shown to react with a mouse monomorphic CD5 (Ly-1), a Group B member of the scavenger receptor cysteine-rich protein superfamily (1). CD5 is a 67 kDa type I transmembrane glycoprotein found on thymocytes, T cells, and a subset of B cells but not on NK cells (2‑6). It is likely a ligand of the B cell differentiation antigen CD72 and is known to associate with CD6 (1). Mouse and human extracellular domains share 55% amino acid sequence indentity.
