ICOS Protein, Mouse (C137S, C138S, HEK293, His)

ICOS protein optimizes essential T-cell responses to foreign antigens, fostering proliferation, lymphokine secretion, up-regulation of cell-cell interaction molecules, and effective B-cell antibody secretion. Crucial for efficient T and B-cell communication, ICOS is vital for normal antibody responses to T-cell dependent antigens. While it doesn't increase interleukin-2 production, it superinduces interleukin-10 synthesis. Moreover, ICOS prevents apoptosis in pre-activated T-cells and plays a critical role in CD40-mediated immunoglobulin class switching. It exists as a homodimer connected by disulfide bonds. ICOS Protein, Mouse (C137S, C138S, HEK293, His) is the recombinant mouse-derived ICOS protein, expressed by HEK293 , with C-His labeled tag and C137S, C138S mutation. The total length of ICOS Protein, Mouse (C137S, C138S, HEK293, His) is 124 a.a., with molecular weight of 27-38 kDa.

The ICOS protein enhances all fundamental T-cell responses to foreign antigens, including proliferation, secretion of lymphokines, up-regulation of cell-cell interaction molecules, and providing effective help for antibody secretion by B-cells. It is essential for facilitating efficient communication between T and B-cells and for normal antibody responses to T-cell dependent antigens. Although it does not increase the production of interleukin-2, it superinduces the synthesis of interleukin-10. Additionally, it prevents apoptosis of pre-activated T-cells and plays a critical role in CD40-mediated class switching of immunoglobulin isotypes. ICOS exists as a homodimer, connected by disulfide bonds.
