CD3 antibodies
We make 3 CD3 antibodies for 2 species, all of them unconjugated. This page explains how they differ, so you can pick the one your experiment needs.
What differs between these antibodies
Which species they are for
Available for Human and Monkey. The species decides which clones there are, so it is the first thing to choose. Many also cross-react with related species, so if you work in one we do not list here, check the reactivity on the product page.
Which clone
We make 2 CD3 antibody clones. A clone is one specific antibody that binds one site on its target, so it is what you cite or reorder by name. Choose the clone that has been shown to work in your application.
Which formulation
All of them are azide-free: they carry no sodium azide, the preservative that is toxic to cells, so they suit work with live cells. Where one clone is sold at more than one concentration, 1 mg/ml and 100 µg/ml, the formulation says which.
About CD3
CD3 (cluster of differentiation 3) is a T cell co-receptor that plays an important role in T cell activation and signal transduction. The CD3 complex is composed of four chains: two CD3ε, one CD3γ, and one CD3δ chain. CD3 forms together with the TCR (α/β or γ/δ heterodimer) and two zeta (ζ) chains the T cell receptor (TCR) complex. CD3 belongs to the immunoglobulin superfamily.
