The CD28 protein is critical for T cell activation, enhancing proliferation, cytokine production, and survival. When linked to TCR/CD3 and CD40L, CD28 promotes the production of IL4 and IL10, thereby regulating immune responses. CD28 Protein, Human/Cynomolgus/Rhesus Macaque (HEK293) is the recombinant human-derived CD28 protein, expressed by HEK293 , with tag free.

Human

CD28 protein plays a pivotal role in T-cell activation, promoting cell proliferation, cytokine production, and T-cell survival. Upon ligation with TCR/CD3 and CD40L costimulation, CD28 enhances the production of IL4 and IL10 in T-cells, contributing to immune response modulation. Additionally, isoform 3 of CD28 facilitates CD40L-mediated activation of NF-kappa-B and kinases MAPK8 and PAK2 in T-cells. The protein forms homodimers through disulfide linkages and interacts with various molecules, including DUSP14, CD80/B7-1, CD86/B7-2/B70, and GRB2. Isoform 3 specifically interacts with CD40LG, highlighting its multifaceted role in mediating immune responses and cellular signaling pathways.
