B7-1/CD80, Rat (HEK293, Fc)

B7-1/CD80, a type I membrane protein, is a member of the B7 family, with an extracellular immunoglobulin constant-like domain and a variable-like domain required for receptor binding.CD80 is also a transmembrane glycoprotein and a member of the Ig superfamily.CD80 has a crucial role in modulating T-cell immune function as a checkpoint protein at the immunological synapse.Its binding to CD28 or CTLA-4 receptors is integral to inducing T-cell proliferation and cytokine production.B7-1/CD80 Protein, Rat (HEK293, Fc) is the recombinant rat-derived B7-1/CD80 protein, expressed by HEK293 , with C-hFc labeled tag.
