Metabotropic glutamate receptor 1 (mGluR1): antibody specificity and receptor expression in cultured primary neurons

J Neurosci Methods. 2012 Mar 15;204(2):221-6. doi: 10.1016/j.jneumeth.2011.11.014. Epub 2011 Dec 2.


The availability of high quality, well-characterized antibodies for molecular and cellular neuroscience studies is important. However, not all available antibodies are rigorously evaluated, nor are limitations of particular antibodies often reported. We have examined a panel of currently available mGluR1 antibodies and have identified which ones are selective for use by western blots and immunocytochemistry. We have also specifically determined whether the antibodies cross-react to recognize mGluR5, by examining (1) tissue from both mGluR1 and mGluR5 knock-out mice and (2) primary cortical cultures, in which mGluR5 is widely expressed but mGluR1 is not. Together, these data provide a baseline characterization of antibodies that can and cannot be reliably used in these types of studies, and will hopefully facilitate and positively impact the research efforts of others studying mGluR1.
