Preparation and Storage
Product Notices
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- An isotype control should be used at the same concentration as the antibody of interest.
- Sodium azide is a reversible inhibitor of oxidative metabolism; therefore, antibody preparations containing this preservative agent must not be used in cell cultures nor injected into animals. Sodium azide may be removed by washing stained cells or plate-bound antibody or dialyzing soluble antibody in sodium azide-free buffer. Since endotoxin may also affect the results of functional studies, we recommend the NA/LE (No Azide/Low Endotoxin) antibody format, if available, for in vitro and in vivo use.
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.

The JJ319 monoclonal antibody specifically recognizes CD28, which is expressed on virtually all T lymphocytes bearing αβ T-cell receptors (TCR), on most γδ TCR-bearing T cells, and on a subset of NK cells. In the thymus, CD28 expression is developmentally regulated during the maturation of αβ TCR-bearing T cells. CD28 is a costimulatory receptor required for activation of T cells; its ligands include CD80 (B7-1) and CD86 (B7-2). Soluble JJ319 mAb costimulates the proliferative responses and IL-2 production of CD4+ and CD8+ T cells activated by anti-αβ-TCR mAb R73 (Cat. no. 554910). The alternate anti-rat CD28 mAb JJ316 (Cat. No. 554992) is capable of directly stimulating T cells in vitro and in vivo.
