The CTAB-dissociated vimentins were unstable, but the breakdown of them was successfully blocked by leupeptin. Thus, with our extraction buffer, composed of 1% CTAB, 1% Tween 40, 10 mM Tris-HCl (pH 7.4) and 25 micrograms/ml leupeptin, almost all of the vimentin as well as the desmin were solubilized, while two thirds or more of actins were ...

Cetyltrimethylammonium Bromide - an overview

Cetyltrimethylammonium bromide (CTAB) was from Amresco Inc. (USA). The mesoporous silica was synthesized by a two-phase route. In a typical synthesis, the lower aqueous phase was a 15.0 g solution of 100H 2 O/0.025CTAB/2.5HCl (molar ratio) and the upper oil phase was 0.327mmol TEOS dissolved in 0.75 mL hexane. The purpose of dilution of TEOS in ...
