Description

CD121a is an 80 kD IL-1 receptor type I. It is a transmembrane glycoprotein and a member of the immunoglobulin superfamily expressed on T cells, thymocytes, dendritic cells, fibroblasts, vascular endothelial cells, epithelial cells and neural cells. CD121a binds the mature forms of IL-1α, IL-1β, and IL-1Ra proteins. High affinity binding and signaling by the type I IL-1 receptor requires CD121a and the accessory protein, IL-1R AcP, which does not bind IL-1 alone, but forms a dimer capable of binding IL-1.

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: immunoprecipitation1 and receptor blocking in vivo1. Clone JAMA-147 prevents the binding of IL-1 to the type 1 IL-R1,2. The LEAF™ or Ultra-LEAF™ purified antibody is recommended for neutralization and functional assays (contact our custom solutions team).

For the most successful immunofluorescent staining results, it may be important to maximize signal over background by using a relatively bright fluorochrome-antibody conjugate (Cat. No. 113506) or by using a high sensitivity, three-layer staining technique (e.g., including a biotinylated antibody (Cat. No. 113504) or biotinylated anti-Armenian hamster IgG second step (Cat. No. 405501), followed by SAv-PE (Cat. No. 405204)).
