| Specificity Profile | More 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. |

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). | |
