GMP Anti-Human CD3 Antibody (OKT3), mAb, Mouse (Cat. No. GMPA02199) was used for primary T cell activation together with anti-Human CD28 antibody. The percentage of activated T cells was measured by flow cytometry. Data showed that GenScript GMP Anti-Human CD3 Antibody (OKT3), mAb, Mouse outperformed the competing products in activating primary T cells.
Jurkat/IL-2-Luc Promoter cells were co-stimulated with a serial of concentrations of GMP Anti-Human CD3 Antibody (OKT3), mAb, Mouse (Cat. No. GMPA02199) and GMP Anti-Human CD28 Antibody (F105), mAb, Mouse (Cat. No. GMPA02213) for 6 h. Receptor-mediated signaling induced luminescence via the activation of the IL-2 pathway.

| Target Background |
CD3 is a member of the
immunoglobulin superfamily, expressed on T cells. It is composed of four
distinct chains (ε, γ, δ, ζ). CD3 antigen can form a complex with the T cell
receptor (TCR) to generate an activation signal in T cells, which plays an
important role in the transduction of TCR signal and the activation of both
cytotoxic T cells (CD8 + naïve T cells) and T helper cells (CD4+ naïve T cells). |
For laboratory research
and ex vivo cell isolation and
culture applications. Direct human use, including taking orally and injection
and clinical use are forbidden.
