Figure 1. Flow Cytometry analysis of human PBMC cells using anti-CD3 antibody (MA1015).
Overlay histogram showing human PBMC cells stained with MA1015 (Blue line).The cells were blocked with 10% normal goat serum. And then incubated with mouse anti-CD3 Antibody (MA1015,1μg/1x106 cells) for 30 min at 20°C. DyLight®488 conjugated goat anti-mouse IgG (BA1126, 5-10μg/1x106 cells) was used as secondary antibody for 30 minutes at 20°C. Isotype control antibody (Green line) was mouse gG (1μg/1x106) used under the same conditions. Unlabelled sample (Red line) was also used as a control.

Protein Function CD3E: The CD3 complex mediates signal transduction.
Background The alpha-beta heterodimeric T-cell antigen receptor binds antigen in association with major histocompatibility complex proteins on host cell surfaces. These 2 disulfide-linked glycoproteins, TCRA and TCRB are associated on T-cell surfaces with a complex of proteins called CD3(formerly T3). Human CD3 consists of at least 4 proteins: gamma, delta, epsilon, and zeta. The CD3-gamma/CD3-delta gene pair is within 300 kb of the CD3-epsilon gene and therefore these genes form a tightly linked cluster on 11q23. The clustering may be significant in terms of their simultaneous activations during T-cell development.
