TRPV1 Antibodies in Action

We would like to thank Dr. Fletcher White, LUMC, for Sharing this data with us:

Images: The CCR2 chemokine receptor colocalized with IB4 and TRPV1, markers of nociceptive neurons, after injury. A) Many lumbar DRG neurons in vehicle-treated rat sensory neurons were positive for IB4, a neuronal phenotype that distinguishes some C-fiber nociceptors (red cells), however there was no expression of the CCR2 protein. B) After perineural gp120/hCD4 treatment, CCR2 protein expression (green cells) was upregulated, and co-localized with IB4. C) Both gp120/hCD4 and ddC treatment resulted in an upregulation of CCR2 expression (green cells) in many small and medium diameter neurons. Again, CCR2 co-localized in a number of IB4 positive cells. D) The TRPV1 channel is present on many nociceptive neurons and is involved in the neuropathic pain mechanism. Under normal conditions, TRPV1 was expressed in neurons (red cells). E) After gp120/hCD4 treatment, CCR2 expression is upregulated (green cells) and colocalized with TRPV1. F) After the combination of gp120/hCD4 and ddC treatments, again CCR2 was upregulated to a similar degree as gp120/hCD4 treatment alone and exhibited some colocalizations with TRPV1.
Scale Bar: 100um.

We would also like to share recent publications referencing our TRPVs:

Antibodies can be detect throguh the use of ELISA test kit. Many medical companies uses this because of its accurate result.
