Clone | EH12.2H7 |
Isotype | Mouse IgG1, κ |
Reactivity | Human, Cross-Reactivity: Chimpanzee, Common Marmoset, Rhesus12, Squirrel Monkey, Cynomolgus |
Formulation | Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and BSA (origin USA). |
Preparation | The antibody was purified by affinity chromatography and conjugated with Brilliant Violet 421™ under optimal conditions. The solution is free of unconjugated Brilliant Violet 421™ and unconjugated antibody. |
Recommended Usage | Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For immunofluorescent staining, the suggested use of this reagent is ≤5 µl per million cells or 5 µl per 100 µl of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.
Brilliant Violet 421™ excites at 405 nm and emits at 421 nm. The standard bandpass filter 450/50 nm is recommended for detection. Brilliant Violet 421™ is a trademark of Sirigen Group Ltd. |
Applications | FC - Quality tested |
Application Notes | Additional reported applications (for the relevant formats) include: blocking of ligand binding1-3. The LEAF™ purified antibody (Endotoxin <0.1 EU/μg, Azide-Free, 0.2 μm filtered) is recommended for functional assays (Cat. No. 329911 and 329912). For highly sensitive assays, we recommend Ultra-LEAF™ purified antibody (Cat. No. 329926) with a lower endotoxin limit than standard LEAF™ purified antibodies (Endotoxin <0.01 EU/µg). " |

Description | The program death 1 (PD-1) receptor CD279 is a 55 kD member of the immunoglobulin superfamily. CD279/PD-1 contains the immunoreceptor tyrosine-based inhibitory motif (ITIM) in the cytoplasmic region and plays a key role in peripheral tolerance and autoimmune disease. CD279/PD-1 is expressed predominantly on activated T cells, B cells and myeloid cells. PD-L1 (B7-H1) and PD-L2 (B7-DC) are ligands of CD279/PD-1 and are members of the B7 gene family. Evidence reported to date suggests overlapping functions for these two PD-1 ligands and their constitutive expression on some normal tissues and upregulation on activated antigen-presenting cells. Interaction of CD279:PD-ligands results in inhibition of T cell proliferation and cytokine secretion. |
Storage | The antibody solution should be stored undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. |
