ICOS (Protein|Antibody|cDNA Clone|ELISA Kit)

All ICOS reagents are produced in house and quality controlled, including 40 ICOS Gene, 6 ICOS Lysate, 6 ICOS Protein, 3 ICOS qPCR. All ICOS reagents are ready to use.

Recombinant ICOS proteins are expressed by HEK293 Cells with fusion tags as C-rabbit IgG-Fc, C-human IgG1-Fc, C-human IgG1-Fc & His.

ICOS cDNA clones are full length sequence confirmed and expression validated. There are 13 kinds of tags for each ICOS of different species, especially GFP tag, OFP tag, FLAG tag and so on. There are three kinds of vectors for choice, cloning vector, expression vector and lentivrial expression vector.

Inducible costimulator (ICOS), also called AILIM (activiation-inducible lymphocyte immunomediatory molecule) is a cell-surface receptor, and belongs to the CD28 family of immune costimulatory receptors consisting of CD28, CTLA-4 and PD-1. The interaction of B7-H2/ICOS plays a critical role in Th cell differentiation, T−B cell interactions which is essential for germinal center formation, and humoral immune responses, and as well as the production of cytokine IL-4. In addition, ICOS is more potent in the induction of IL-1 production, a cytokine important for suppressive function of T regulatory cells. The B7-1/B7-2--CD28/CTLA-4 and ICOS-B7RP-1 pathway provides key second signals that can regulate the activation, inhibition and fine-tuning of T-lymphocyte responses. ICOS stimulates both Th1 and Th2 cytokine production but may have a preferential role in Th2 cell development. Moreover, The B7-1/B7-2-CD28/CTLA-4 and ICOS-B7RP-1 pathway has been suggested of being involved in the development of airway inflammation and airway hyperresponsiveness.Immune Checkpoint
