CTLA-4, Rat (HEK293, His)

CTLA-4 protein inhibits T-cell responses by binding strongly to CD80 and CD86 receptors, surpassing CD28. This affinity allows CTLA-4 to effectively regulate T-cell activation and immune responses. The balance between inhibitory and stimulatory signals controlled by CTLA-4 and its ligands modulates T-cell-mediated immune reactions. CTLA-4 Protein, Rat (HEK293, His) is the recombinant rat-derived CTLA-4 protein, expressed by HEK293 , with C-His labeled tag.
