In immature (CD34+) T-cells, CD5 is weakly expressed, the intensity of expression increasing with maturation. CD5 is also expressed in a small subset of normal human B-cells (20% of B-cells in the peripheral blood, scattered cells in the lymph node mantle zone). The CD5+ cells are probably involved in B-T interaction and their ligand is CD72 which is expressed on all B cells. It appears that CD5+ B-cells on activation primarily produce IgM. They also produce more autoantibodies than normal CD5 negative B-cells. Thus, the CD5+ B-cell population is expanded in rheumatoid arthritis and systemic lupus erythematosus. The CD5 antibody reacts with CD5 expressed on B and T cells, and may be a useful aid for the classification of B and T-cell malignancies. This includes B-cell chronic lymphoid leukemia (B-CLL), B-cell small lymphocytic lymphoma (B-SLL), mantle cell lymphoma (MCL) and T-cell lymphoma and leukemia.\u003c\/p\u003e\u003cp\u003eThis anti-CD5 antibody is supplied as Purified (Rabbit, Recombinant Rabbit Monoclonal, clone C5\/6438R, Rabbit IgG, Unconjugated) and is designed to support common target-detection workflows after the on-page specifications.\u003c\/p\u003e\u003ch2\u003eKey elements and design rationale\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTarget:\u003c\/strong\u003e CD5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormat:\u003c\/strong\u003e Purified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocalization:\u003c\/strong\u003e Cell Surface\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecies reactivity:\u003c\/strong\u003e Human\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplications (listed):\u003c\/strong\u003e IHC-P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConjugate:\u003c\/strong\u003e Unconjugated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClone and antibody class:\u003c\/strong\u003e Recombinant Rabbit Monoclonal, clone C5\/6438R, Rabbit IgG\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eBecause antibody performance can depend on epitope context, sample preparation, and biological state, interpret signals using appropriate controls and orthogonal evidence when possible.\u003c\/p\u003e\u003ch2\u003eBiological background\u003c\/h2\u003e\u003cp\u003eCD5 is referenced in public gene\/protein resources (e.g., UniProt and NCBI Gene), which provide curated names\/synonyms, protein features, and pathway context.
