Clone 7E.17G9

(RUO)

Product Details

Brand: BD Pharmingen™

Alternative Name: ICOS; Ailim; CCLP; CRP-1; Ly115; Inducible T-cell costimulator

Reactivity: Mouse (QC Testing)

Isotype: Rat IgG2b, κ

Immunogen: Mouse Icos cDNA and ICOS hexahistidine fusion protein

Application: Flow cytometry (Routinely Tested), Blocking (Reported)

Concentration: 1.0 mg/ml

RRID: AB_394389

Storage Buffer: No azide/low endotoxin: Aqueous buffered solution containing no preservative, 0.2µm sterile filtered. Endotoxin level is ≤0.01 EU/µg (≤0.001 ng/µg) of protein as determined by the LAL assay.

Regulatory Status: RUO

Preparation And Storage

Store undiluted at 4°C. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. This preparation contains no preservatives, thus it should be handled under aseptic conditions.

Recommended Assay Procedures

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.

Product Notices

Since applications vary, each investigator should titrate the reagent to obtain optimal results.

Antibody Details

7E.17G9

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.

Format Details

NA/LE

NA/LE refers to the culture and purification methods and buffer used to produce purified antibodies with no azide and low endotoxin: Aqueous buffered solution containing no preservative, 0.2µm sterile filtered. Endotoxin level is ≤0.01 EU/µg (≤0.001 ng/µg) of protein as determined by the LAL assay.NA/LE are perfectly suited to be used in culture or in vivo (for nonhuman studies) for functional assays — blocking, neutralizing, activation or depletion — where the presence of azide may damage cells or exogenous endotoxin may signal or activate cells.

Format: NA/LE
