Introduction
Description: CTAB is a cationic surfactant that has been used to complex and precipitate high MW plant DNA. Its activity is neutralized by anionic surfactants (e.g. SDS).CTAB has bactericidal activity against both gram-positive and gram-negative organisms. It can be used with thePhytoSelect Basal Medium (P6800) for the selection of Burkholderia glumae, Acidovorax avenae, andPectobacterium carotovorum. See product information sheet for P6800 for details.Synonyms: CTAB; HTAB; Centimide; Cetrimide; Cetrimonium bromide; Cetyltrimethylammonium Bromide; Palmityltrimethylammonium bromide; Hexadecyltrimethylammonium Bromide

Application Notes
CTAB is a cationic detergent that is often used to complex and precipitate high molecular weight DNA when the NaCl concentration drops from 0.7M to 0.35M (Murray and Thompson 1980). Its activity is neutralized by anionic detergents (such as SDS). It also exhibits bactericidal activity against both gram positive and negative organisms.
