I would like to measure DRG response using Elisa. Im thinking to measure GABA, Glutamate and CGRP. what else do you think is important to measure too? and any one try to measure those mediators before? any recommended company?
I don't understand your question. Are you looking for a molecular marker of sensory neurons? Or a molecular marker of activity? If it is the later case, may be you can use c-fos.
It depends on the nature of the stimulus, I suppose. If you're hitting your DRG with TRP channel activators, then CGRP or a Substance P ELISA will give you a good readout.
