Our mouse Kv2.1 K+ channel FL490 conjugate monoclonal antibody from NeuroMab is produced in-house from clone K89/34. It detects hamster, human, mouse, non-human primate, and rat Kv2.1 K+ channel and is purified by Protein A chromatography. KO validated. Works in IHC, ICC.
Kv 2.1 K+ channel (Potassium voltage-gated channel subfamily B member 1), which is encoded by KCNB1 gene, is a member of the Potassium voltage-gated channel familly. This protein, mainly expressed in the central nervous system, functions as a delayed rectifier. Indeed, it regulates the action potential (AP) repolarization as well as duration and frequency of repetitive AP firing in neurons, muscle cells and endocrine cells. Kv2.1 K+ channel switches between open or closed conformation in response to the voltage difference across the membrane. This process directs the voltage-dependent potassium ion permeability of excitable membranes, which lets potassium ions pass in accordance with their electrochemical gradient. Kv2.1 K+ channel is widely used as a marker to measure membrane excitability in hippocampal neurons.
