Description

CD275 is a 40 kD protein, also known as ICOS ligand, B7-RP1, B7-H2, and B7h. It is a member of the immunoglobulin receptor superfamily expressed on splenic B cells, dendritic cells, and macrophages. The expression of this antigen is increased by TNF-α stimulation and is highly upregulated by local inflammation. B7RP1 binds to ICOS and co-stimulates T cell and B cell responses. Two isoforms of this protein have been reported to occur as a result of alternative splicing. These isoforms show differential tissue distribution.

Application

FC - Quality tested
Recommended Usage

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤1.0 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

Excitation Laser
Blue Laser (488 nm)
Green Laser (532 nm)/Yellow-Green Laser (561 nm)
Application Notes

Additional reported applications (for the relevant formats) include: in vitro and in vivo blocking of ligand binding1,2. For most successful immunofluorescent staining results, it may be important to maximize signal over background by using a relatively bright fluorochrome-antibody conjugate (Cat. No. 107405) or by using a high sensitivity, three-layer staining technique (e.g., including a biotinylated antibody (Cat. No. 107404) or biotinylated anti-rat IgG second step (Cat. No. 405402), followed by SAv-PE (Cat. No. 405204)). The LEAF™ purified antibody (Endotoxin <0.1 EU/µg, Azide-Free, 0.2 µm filtered) is recommended for functional assays (Cat. No. 107408). For in vivo studies or highly sensitive assays, we recommend Ultra-LEAF™ purified antibody (Cat. No. 107410) with a lower endotoxin limit than standard LEAF™ purified antibodies (Endotoxin <0.01 EU/µg).
