Scientific background
TRP channels are a large family (about 28 genes) of plasma membrane, non-selective cationic channels that are either specifically or ubiquitously expressed in excitable and non-excitable cells.1 According to IUPHAR the TRP family comprises of three main subfamilies on the basis of sequence homology; TRPC, TRPM and TRPV (to date, three extra subfamilies are considered to belong to the TRP family; the TRPA, TRPML, and TRPP).1-4 The TRPV subfamily consists of six members, TRPV1-6.5
TRPV4 (also named OTRPC4) is activated under hypotonic conditions and serves as an osmoreceptor. TRPV4 is expressed in brain, liver, kidney, heart, testis and salivary gland.6
Lyophilized Powder
Anti-TRPV4 Antibody (#ACC-034) is a highly specific antibody directed against an epitope of the rat protein. The antibody can be used in western blot, immunoprecipitation, indirect flow cytometry, immunohistochemistry, and immunocytochemistry applications. It has been designed to recognize TRPV4 from human, rat, and mouse samples.

Knockout validation of Anti-TRPV4 Antibody in mouse kidney.Immunohistochemical staining of mouse kidney sections using Anti-TRPV4 Antibody (#ACC-034) and Anti-Aquaporin 2-ATTO Fluor-550 Antibody (#AQP-002-AO). TRPV4 staining (green, upper panels) is detected in both the connecting tubules (CNT) and the collecting ducts (CCD). AQP2 immunostaining (red) is also observed in the CCD and CNT. TRPV4 staining is not observed in the sections from TRPV4-/- mice. Adapted from Berrout, J. et al. (2012) J. Biol.

Expression of TRPV4 in rat perihematomal area following ICH.Immunohistochemical staining of rat brain sections 24 hours after intracerebral hemorrhage (ICH) induction using Anti-TRPV4 Antibody (#ACC-034). At 24 hours post-ICH, TRPV4 immunostaining (red) was detected on neurovascular structures, perivascular astrocytes and endothelial cells in the perihematomal area. TRPV4 staining coincided with that of GFAP (lower panels), an astrocyte marker and von Willebrand factor (vWF) (upper panels), a marker of BBB. Nuclei were stained using DAPI.
