Immunogen: Mouse ICOS cDNA and ICOS hexahistidine fusion protein

Klon: 7E-17G9

Beschreibung: The 7E.17G9 antibody reacts with the 47-57 kD ICOS protein, also known as inducible costimulatory molecule, andH4. This protein is homologous to the CD28/CTLA-4 proteins. ICOS is expressed on activated T cells and a subset ofthymocytes and can costimulate T cells and induce proliferation. In addition ICOS has been shown to be involved inhumoral immune responses (B cell germinal center formation). The ICOS ligand, B7h/B7RP-1 and B7-H2 isconstitutively expressed in B cell areas of secondary lymphoid organs and can be induced in other tissues by LPS.ICOS stimulation has been shown to potentiate TCR-mediated IL-4 and IL-10 production and has been proposed toplay a role in Th2 cell development. ICOS stimulation has been shown to be involved in airway tolerance and thedownregulation of pulmonary inflammation.

Anwendungen

Applikationshinweise: Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis.
