Product Description	Recombinant Biotinylated Human CD4/LEU3 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.It contains Lys26-Trp390.
Product Background	CD4, also known as L3T4, T4, and W3/25, is an approximately 55 kDa type I transmembrane glycoprotein that is expressed predominantly on thymocytes and a subset of mature T lymphocytes. It is a standard phenotype marker for the identification of T cell populations.Integral membrane glycoprotein that plays an essential role in the immune response and serves multiple functions in responses against both external and internal offenses. In T-cells, functions primarily as a coreceptor for MHC class II molecule:peptide complex.
Product Category	Recombinant Protein / Antibody discovery / CAR-T targets
