Rabbit anti Rat Potassium Channel

Rabbit anti Rat Potassium Channel, Polyclonal, IgG

Background: Pore-forming (alpha) subunit of voltage-gated rapidly inactivating A-type potassium channels. May contribute to Icurrent in heart and current in neurons. Channel properties are modulated by interactions with other alpha subunits and with regulatory subunits In response to membrane depolarization, Kv4.2 channels accumulate in the closed-inactivated state(s), from which they directly recover, bypassing the open state. Kv4.2 is a substrate for ERK in vitro and in vivo, and suggest that ERK may regulate potassium-channel function by direct phosphorylation of the pore-forming alpha subunit.

Positive Control: Highly expressed in heart and throughout the brain, with similar levels in cortex and hypothalamus, and much higher levels in hippocampus, dentate gyrus and the habenular nucleus of the thalamus. Detected at similar levels in heart atrium and ventricle. Detected in aorta, cardiac and smooth muscle.

Purification Method: Ammonium Sulfate Precipitation

Concentration: See vial for concentration

Source: Rabbits were immunized with a peptide representing amino acids 453-470 of rat Kv4.2 conjugated to KLH.

Formulation: Provided as solution in phosphate buffered saline with 0.08% sodium azide
