CD274, also known as B7-H1 or programmed death ligand 1 (PD-L1), is a 40 kD type I transmembrane protein and a member of the B7 family within the immunoglobulin receptor superfamily. It is expressed on T cells, B cells, NK cells, dendritic cells, IFN-γ activated endothelial cells, and monocytes. B7-H1 is one of the ligands of PD-1. The interaction of B7-H1 with PD-1 plays an important role in the inhibition of T cell responses. Other studies have shown that B7-H1 is able to costimulate T cell growth and cytokine production. CD274 is involved in costimulation essential for T cell proliferation and production of IL-10 and IFN-γ, in an IL-2-dependent and a PD-1-independent manner. Its interaction with PD-1 inhibits T cell proliferation and cytokine production.Product Details
- Antibody Type

- The GoInVivo™ antibody was purified by affinity chromatography. The antibody is bottled at the concentration indicated on the vial, typically between 1 mg/ml and 3 mg/ml.
- Storage & Handling
- The antibody solution should be stored undiluted between 2°C and 8°C. This GoInVivo™ solution contains no preservative; handle under aseptic conditions.
FC - Quality tested
IF, Block - Reported in the literature
- 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 or 100 µl of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.
For in vivo and in vitro applications, we recommend to perform a pilot experiment to determine the optimal concentration to use for each particular experiment.
