Application Notes:

Additional reported applications (for the relevant formats) include: immunoprecipitation1-3, blocking of ligand binding1-3, and immunohistochemical staining of acetone-fixed frozen sections3.

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤0.5 µg per 106 cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

LPS-stimulated LOU rat splenocytes (3

LPS-stimulated LOU rat splenocytes (3 days) were stained with CD80 (clone 3H5) PE (filled histogram) or mouse IgG1, κ PE isotype control (open histogram).


CD80 is a 60 kD member of the immunoglobulin superfamily also known as B7-1, B7, and BB1. It is expressed on antigen presenting cells and activated T and B cells, and is a ligand for CD28 and CD152 (CTLA-4). CD80/CD28 interactions are important for T and B cell co-stimulation, while CD80/CD152 lead to the inhibition of T cell responses. The 3H5 antibody can block the co-stimulatory activity of CD80.
