CD3 delta protein is a component of the TCR-CD3 complex on T lymphocytes and plays a crucial role in adaptive immunity. Activated by APC, TCR signals through the CD3 chain, including CD3D, CD3E, CD3G, and CD3Z. CD3D-CD3E Heterodimer Protein, Cynomolgus (HEK293, Fc-Flag&Fc-His) is a recombinant protein dimer complex containing cynomolgus-derived CD3D-CD3E Heterodimer protein, expressed by HEK293 , with C-hFc, C-Flag, C-6*His labeled tag. CD3D-CD3E Heterodimer Protein, Cynomolgus (HEK293, Fc-Flag&Fc-His), has molecular weight of 40-60 kDa.
