CD5 Monoclonal Antibody (YKIX322.3), PerCP-eFluor™ 710, eBioscience™, Invitrogen™

Description

Description: This YKIX322.3 monoclonal antibody reacts with canine CD5, also known as Ly-1. CD5 is a 67-kDa type I transmembrane glycoprotein expressed on thymocytes and mature T cells. Studies have demonstrated that NK cells in dogs also express CD5, but at lower levels. In dogs, CD5 is not detectable on B cells or B cell lines. Applications Reported: This YKIX322.3 antibody has been reported for use in flow cytometric analysis. Applications Tested: This YKIX322.3 antibody has been pre-titrated and tested by flow cytometric analysis of normal canine peripheral blood cells. This can be used at 5 μL (0.125 μg) per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. PerCP-eFluor™ 710 can be used in place of PE-Cy5, PE-Cy5.5 or PerCP-Cy5.5. PerCP-eFluor™ 710 emits at 710 nm and is excited with the blue laser (488 nm). Please make sure that your instrument is capable of detecting this fluorochrome. For a filter configuration, we recommend using the 685 LP dichroic mirror and 710/40 band pass filter, however the 695/40 band pass filter is an acceptable alternative.

CD5 is a 67 kDa human T-lymphocyte single-chain transmembrane glycoprotein. CD5 is present on all mature T-lymphocytes, on most of thymocytes and on many T-cell leukemias and lymphomas. CD5 also reacts with a subpopulation of activated B-cells and may act as a receptor in regulating T-cell proliferation. CD5 is found on 95% of thymocytes and 72% of peripheral blood lymphocytes. In lymph nodes, the main reactivity is observed in T cell areas. CD5 is expressed by many T cell leukemia, lymphomas, and activated T cells. Diseases associated with CD5 dysfunction include thymus cancer and Richter's Syndrome.
