#

Voltage-gated sodium channels are present in the membrane of most excitable cells and comprise of one pore-forming α subunit which may be associated with either one or two β subunits. The family of sodium channels has nine known members named Nav 1.1 through Nav 1.9 with the majority being found primarily in the central nervous system, peripheral neurons and dorsal root ganglia. In addition, some sodium channels are found in cardiac myocytes (primarily Nav 1.5) while Nav 1.4 is located in skeletal muscle.

SB Drug Discovery offers a comprehensive panel of sodium channel assays for HTS, lead optimization studies and selectivity profiling. Our assays have been validated by experienced in-house electrophysiologists using rigorously optimized SOPs to ensure data of the highest quality and consistency.
