Extra Details:: CD5/Lyt-1 antigen is a monomeric type I transmembrane glycoprotein expressed on thymocytes, T lymphocytes, and a subset of B lymphocytes, but not on natural killer (NK) cells.1-3 It has been identified as the major ligand of the B-cell antigen CD72.4, 5 The frequency of CD5+ B cells exhibits strain-dependent variation, and the phenotypic, anatomical, functional, developmental, and pathological characteristics of the CD5+ B cells suggest that they may represent a distinct lineage, known as B-1 cells (reviewed in 6). Binding of CD5 on the T cell surface can augment alloantigen- or mitogen-induced lymphocyte proliferation and induces increased cytosolic free calcium, IL-2 secretion, and IL-2R expression.7-12 It has been proposed that CD5 negatively regulates signal transduction mediated by the T-cell and B-cell receptors.13, 14 Applications: • Identification and enumeration of CD5+ cells by flow cytometry 15 • Immunoprecipitation 15 • Immunohistochemistry (frozen sections) 15 • T cell activation 15 • Western blotting 15 Recommended Dilution: Flow Cytometry: ≤ 0.2ug/10e6 cells Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C before opening. DO NOT FREEZE! Stable at 4°C as an undiluted liquid. Dilute only prior to immediate use. Stable for at least 12 months. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer.
