Ctab solubility
WebCTAB is a cationic detergent, soluble in H2O and readily soluble in alcohol. CTAB is commonly used in the preparation and purification of genomic DNA from bacteria … WebCTAB was the object of the research very often. Depend-ing on the conditions it has been reported that CTAB adsorbs on mica as a compact monolayer [9], as a stable hydrophobic surface [10], as a bilayer [11] or forms aggregates [12]. For the preparation of CTAB self-assembled films on mica numerous adsorption proto-
