권장 분석 절차
The antigen is expressed at only moderate density on activated T lymphocytes. It may be desirable to amplify the staining by using a biotinylated second-step antibody with a bright third-step reagent, such as Streptavidin-PE (Cat. No. 554061). Furthermore, we have found that polyclonal goat anti-rat Ig is weakly reactive with this rat IgG2b mAb, so we recommend the use of biotinylated anti-rat IgG2b mAb RG7/11.1 (Cat. No. 553898) as the second step.

The 7E.17G9 monoclonal antibody specifically binds to CD278, the Inducible Costimulatory molecule (ICOS), a 47-57 kDa homodimeric glycoprotein of the CD28 family of costimulatory molecules. ICOS is expressed on subpopulations of CD4-CD8- and CD4+CD8- (but not CD4-CD8+ or CD4+CD8+) thymocytes, on some T-cell lines, and on small numbers of peripheral leukocytes. It is upregulated on T lymphocytes following activation via the T-cell receptor. The T-cell activation marker H4 is the same molecule as ICOS. ICOS is a costimulatory receptor, and its ligand on antigen-presenting cells has been called B7RP-1, GL50, B7h, B7-H2, or LICOS. There is considerable evidence that the interaction of ICOS with its ligand is involved in the regulation of many, but not all, T-cell-mediated immune responses.
