CD28 Monoclonal Antibody (JJ319), eBioscience
PRODUCT DETAILS
Host: Mouse
Isotype: IgG1
Clonality: Monoclonal
Clone: JJ319
Reactivity: Rt
Application: Flow Cytometry
Tested Dilution: 1 µg/test
Concentration: 0.5 mg/mL
Storage: 4°C
Formulation: PBS with 0.09% sodium azide; pH 7.2
Purification: Affinity chromatography
Data Sheet: TDS
Specific Information
Description: The JJ319 monoclonal antibody reacts with the rat CD28 molecule, expressed by thymocytes, mature T cells, and a subset of NK cells. CD28 is a ligand for CD80 (B7-1) and CD86 (B7-2) and is a potent costimulator of T cells. Signaling through CD28 augments IL-2 and IL-2 receptor expression as well as cytotoxicity of CD3-activated T cells. No reactivity of JJ319 is observed on mouse T cells.
Applications Reported: The JJ319 antibody has been reported for use in flow cytometric analysis, and immunoprecipitation. It has also been reported in in vitro T cell costimulation. (Please use Functional Grade purified JJ319, Product # 16-0280, in functional assays).
Applications Tested: This JJ319 antibody has been tested by flow cytometric analysis of rat splenocytes. This can be used at less than or equal to 1 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
Purity: Greater than 90%, as determined by SDS-PAGE.
Aggregation: Less than 10%, as determined by HPLC.
Filtration: 0.2 µm post-manufacturing filtered.
For Research Use Only. Not for use in diagnostic procedures. Not for resale without express authorization.
