应用案例

• 抗人CD3和CD28抗体激活T细胞

   抗CD3和抗CD28抗体与 T 细胞表面表达的相应CD标志物结合，分别为T细胞激活提供第一和第二信号。共刺激的激活信号诱导T细胞快速增殖，在适应性免疫反应和免疫治疗中起着至关重要的作用。

    Figure 1. 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 were 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.

    Figure 2. CHO-K1/CD80 cells were plated 15 h before adding Jurkat/IL-2-Luc Promoter cells, then Jurkat/IL-2-Luc Promoter cells were stimulated with a serial of concentrations of Anti-Human CD3 Antibody (OKT3), mAb, Mouse (Cat. No. A02199) for 5 h. Receptor-mediated signaling induced luminescence via activation of the IL-2 pathway.

    Figure 3. Jurkat/IL-2-Luc Promoter cells were co-stimulated with a serial of  concentrations of Anti-Human CD28 Antibody (F105), mAb, Mouse (Cat. No. A02213) and 1 μg/mL of Anti-Human CD3 Antibody (OKT3), mAb, Mouse (Cat. No. A02199) for 5 h. Receptor-mediated signaling induced luminescence via activation of the IL-2 pathway.

    Figure 4. Primary T cells were stimulated with 5 μg/mL of Anti-Human CD3 Antibody (OKT3), mAb, Mouse (Cat. No. A02199) (left), competing anti-Human CD3 antibody (middle), negative control (NC, right) as well as anti-Human CD28 antibody (all panels) for 72 h, respectively. CD25/CD69 expression was detected by flow cytometry to characterize cell activation.

    

    Figure 5. Primary T cell clumping was observed by a microscope after T cell activation (72 h) (right) using Anti-Human CD3 Antibody (OKT3), mAb, Mouse (Cat.
