Research context & evidence
Target information is kept separate from product-level validation so you can review the biology and the reagent evidence independently.
CD80 / B7-1 provides an important costimulatory signal for T-lymphocyte activation by acting as a ligand for CD28, augmenting MHC/T-cell receptor signalling. CD80 also binds CTLA-4, which can oppose CD28-mediated priming and limit T-cell activation, placing CD80 at a key immune costimulation and checkpoint interface.
CD80 / B7-1 is commonly studied in antigen-presenting-cell biology, T-cell costimulation, CD28 and CTLA-4 signalling, humoral immunity and immune-oncology models.
