Pinpointing Neuropathic Pain

I am pleased to feature our Guinea Pig P2X3 Antibody as a tool for studying the root causes of Neuropathic Pain.

In this study, the authors showed ablation of nonpeptidergic fibers in a chronic constriction injury model caused significant sympathetic and parasympathetic P2X3 fiber sprouting, and led to an exacerbated pain response. This was an unexpected finding, as it has been suggested that nonpeptidergic fibers play a major role in mechanical pain, and suggests that these fibers play a complex role in the development of neuropathic pain: Anna M.W. Taylora, Maria Osikowicza, Alfredo Ribeiro-da-Silva. Consequences of the ablation of nonpeptidergic afferents in an animal model of trigeminal neuropathic pain. PAIN. Volume 153, Issue 6, June 2012, Pages 1311–1319. doi.org/10.1016/j.pain.2012.03.023....Sections were then incubated for 48 hours at 4°C with a guinea pig polyclonal anti-P2X 3 antibody (1:25,000; Neuromics, Edina, MN, USA), diluted in PBS-T. Following primary antibody incubation, sections were treated with a biotin-conjugated...

Great post explaining neuropathic pain
