Anti-GRK 2 Antibody

This unconjugated polyclonal reagent from Antibodies.com targets GRK2 (G-protein-coupled receptor kinase 2), a serine/threonine kinase central to GPCR desensitization and beta-adrenergic receptor signaling. Raised in rabbit, the antibody is supplied as 100 µl of ready-to-use reagent and is validated for western blot, immunohistochemistry, and ELISA workflows across human, mouse, and rat samples. Researchers studying cardiovascular signaling, beta-arrestin recruitment, or GRK2-mediated regulation of G protein-coupled receptors rely on this reagent to probe endogenous expression in cell lysates and fixed tissue sections. Its polyclonal format allows recognition of multiple epitopes on the target kinase, supporting robust detection in applications where monoclonal antibodies may miss splice variants or post-translationally modified forms.
