The CD4 protein is an integral membrane glycoprotein that plays a key role in immune responses. In T cells, it serves as a coreceptor for MHC class II molecules, interacting with T cell receptors and initiating intracellular signaling pathways. CD4 Protein, Human (183a.a, HEK293, His) is the recombinant human-derived CD4 protein, expressed by HEK293 , with C-His labeled tag.
