The Mouse CD279 (PD-1) Monoclonal Antibody (29F.1A12) is a specialized tool for researchers studying immune checkpoints, particularly the PD-1 pathway. This antibody targets the CD279 protein, a key player in immune regulation and tolerance. It is purified from mouse hybridoma culture supernatant, ensuring high specificity and sensitivity in detecting PD-1 in various biological samples.PD-1, also known as programmed cell death protein 1, is a crucial checkpoint receptor that inhibits T cell activation and prevents autoimmunity. Dysregulation of the PD-1 pathway is implicated in various diseases, including cancer and chronic infections.
By using this monoclonal antibody, researchers can accurately monitor PD-1 expression levels, investigate its role in immune responses, and explore potential therapeutic interventions targeting the PD-1 pathway.With its reliable performance in techniques such as flow cytometry, immunofluorescence, and immunohistochemistry, the Mouse CD279 (PD-1) Monoclonal Antibody (29F.1A12) is a valuable asset for immunologists, oncologists, and researchers delving into the intricate mechanisms of immune tolerance and immune evasion in disease settings.
Each lot of this antibody is quality control tested by flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.25 µg per 106 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.

Background:
CD279, also known as programmed death-1 (PD-1), is a 50-55 kD glycoprotein belonging to the CD28 family of the Ig superfamily. PD-1 is expressed on activated splenic T and B cells and thymocytes. It is induced on activated myeloid cells as well. PD-1 is involved in lymphocyte clonal selection and peripheral tolerance through binding its ligands, B7-H1 (PD-L1) and B7-DC (PD-L2). It has been reported that PD-1 and PD-L1 interactions are critical to positive selection and play a role in shaping the T cell repertoire. PD-L1 negative costimulation is essential for prolonged survival of intratesticular islet allografts.
