sodium cholate
activates at 0.07-0.7% w/v, loss of about 75% activation potency in absence of Ca2+
sodium taurodeoxycholate
-
1.0 mg/ml, slight activation
taurodeoxycholate
may substitute for Triton X-100 at 0.5%
taurodeoxycholate hydrate
TDC, activates at 0.07-0.7% w/v, TDC-based enhancement of hydrolysis requires the presence of Ca2+. In the absence of Ca2+, GM1 hydrolysis is only 2.9%, 14fold lower than the same case of Triton X-100
Triton X-100
Tween 80
activates 0.07-0.7% w/v, loss of about 65% activation potency in absence of Ca2+
