CD28 provides the critical co-stimulatory signal that, together with TCR engagement, drives full T-cell activation, proliferation, and cytokine production. Clone JJ319 is a mouse IgG1 kappa monoclonal antibody recognising rat CD28, validated for blocking, ELISA, flow cytometry, immunofluorescence, and immunoprecipitation. Anti-CD28 JJ319 is supplied in a low-endotoxin format suitable for in vivo use and produced in scalable milligram to gram quantities for bulk and high-throughput laboratories. This non-therapeutic reagent, intended for research use only, delivers reproducible lot-to-lot performance for rat T-cell co-stimulation and activation studies that demand consistent bulk supply.
