Recombinant Rat CD6/TP120 Protein (His Tag)(Active) Size: 100μg Catalogue Number: PKSR030241-100 Citations, Manuals and MSDS Available upon request. Abbreviation: CD6; TP120 Target Symptom: CD6 Target Species: Rat Expression Host: HEK293 Cells Application: Cell culture; ELISA Fusion Tag: C-His UNIProt ID: Q812A4 Accession: Q812A4 Background: T-cell differentiation antigen CD6, also known as TP120 and CD6, is a single-pass type I membrane protein which contains threeSRCR domains. CD6 / TP120 is a cell surface glycoprotein expressed primarily on T cells, it may function as a costimulatory molecule and may play a role in autoreactive immune responses. CD6 / TP120 is expressed by thymocytes, mature T-cells, a subset of B-cells known as B-1 cells, and by some cells in the brain. CD6 ligand termed CD166 (previously known as activated leukocyte cell adhesion molecule, ALCAM ) has been identified and shown to be expressed on activated T cells, B cells, thymic epithelium, keratinocytes, and in rheumatoid arthritis synovial tissue. CD6 / TP120 binds to activated leukocyte cell adhesion molecule ( CD166 ), and is considered as a costimulatory molecule involved in lymphocyte activation and thymocyte development. CD6 / TP120 partially associates with the TCR / CD3 complex and colocalizes with it at the center of the mature immunological synapse (IS) on T lymphocytes. During thymic development CD6-dependent signals may contribute both to thymocyte survival, and to the overall functional avidity of selection in both man and mouse. Activity: 1. Immobilized rat CD6-His at 10 μg/mL (100 μL/well) can bind rat ALCAM-Fc3, The EC50 of rat ALCAM-Fc3 is 19.5-45. 5 ng/ml. 2. Measured by the ability of the immobilized protein to support the adhesion of Jurkat human acute T cell leukemia cells. When 8 x 10⁴cells/well are added to rat CD6-His coated plates (10μg/mL, 100 μL/well), approximately 39.2% will adhere after 60 minutes at 37℃.
