Polyclonal Antibodies against RGS7, a Regulator of G Protein Signaling, for Research and Diagnostic Use

Posted Jun 14 2011 8:00pm

Description of Invention:
Investigators at the National Institutes of Health have generated a polyclonal antibody against the Regulator of G protein Signaling Protein 7 (RGS7). The RGS7 protein regulates neuronal G protein signaling pathways and inhibits signal transduction by increasing the GTPase activity of G protein alpha. RGS7 may play an important role in synaptic vesicle exocytosis and in the rapid regulation of neuronal excitability and the cellular responses to stimulation. This polyclonal antibody was generated by using a purified fusion protein containing the regulator of guanine nucleotide-binding protein signaling (RGS) C-terminal region of bovine RGS. The antibody specifically recognizes RGS7 of mouse, rat, and human origin. The antibody is useful for studying the expression, functions, and interactions of RGS7 by Western blot and immunofluorescence analysis.

  • Basic research tool for the study of RGS7. Reagent for diagnostic applications such as Western Blotting, ELISA, immunofluorescence and immunohistochemistry in fixed tissue samples.
  • Reagent for biochemical techniques such as immunoprecipitation. Development of diagnostics or therapeutics for diseases of the nervous system linked to RGS protein-regulated signaling including Parkinson’s disease, schizophrenia, seizure disorders, multiple sclerosis, and opiate addiction.
