Flow Cytometry (Extracellular): HEK-293F cells transiently transfected with human CD28 were stained with CD28 Monoclonal Antibody (CSB0012) (green) or isotype control antibody (gray), followed by AlexaFluor 647-conjugated anti-Mouse IgG secondary antibody. HEK-293F cells transiently transfected with an empty control vector were also stained with CD28 Monoclonal Antibody (CSB0012) (blue).

Specificity ProfileMore Information

The specificity of CD28 Monoclonal Antibody (CSB0012) was tested on the Membrane Proteome Array™ and shown to be specific for human CD28.

The Membrane Proteome Array™ contains 6,000 different human membrane proteins, each expressed in unfixed human cells to ensure native conformation and post-translational modifications. The Membrane Proteome Array™ represents the industry standard for determining the binding specificity of antibodies and other protein ligands.
