Technical Data
BKCa Channel (1184-1200) (High-conductance Ca2+ activated Potassium Channel, K Ca 1.1 , Maxi K +, KCNMA1)
KCa 1.1 (BK Ca , Maxi K +or slo) is part of a structurally diverse group of K +channels that are activated by an increase in intracellular Ca 2+ . K Ca 1.1 shows a large single channel conductance when recorded electrophysiologically and hence its name. It differs from the rest of the subfamily members in that it can be activated by both an increase in intracellular Ca 2+ and by membrane depolarization. KCa 1.1 is expressed in virtually all cell types where it causes hyperpolarization and helps to connect between intracellular Ca 2+ signaling pathways and membrane excitability. Indeed, K Ca 1.1 channels have a crucial role in smooth muscle contractility, neuronal spike shaping and neurotransmitter release.

Suitable for use in Western Blot, Immunoprecipitation and Immunohistochemistry. Other applications have not been tested.

Recommended Dilutions:
Western Blot: 1:500. Rat brain membrane
Immunoprecipitation: 4ug. Rat brain lysate
