Packinggroup: III
Biological Activity: Potent blocker of high-conductance Ca 2+ -activated K + (BK Ca ) channels. Binds to the α -subunit of BK Ca (K i = 1.9 nM for block of currents in α -subunit-expressing oocytes) and enhances binding of charybdotoxin to BK Ca channels in vascular smooth muscle. Also inhibits sarco/endoplasmic reticulum Ca 2+ -ATPase (IC 50 = 5-50 μ M).
Storage Temperature: 2-8°C
Color: faint yellow
