Product introduction:

Cetyltrimethylamine bromide: CTAB is a cationic detergent with the property of precipitating nucleic acids and acidic polyglycans from a solution of low ionic strength, in which the protein and neutral polyglycans remain in the solution, in a solution of high ionic strength, forming complexes with proteins and other polyglycans other than most acidic polyglycans, except that nucleic acids cannot be precipitated.

How it Works:

CTAB is a cationic detergent that precipitates nucleic acids and acidic polysaccharides from a solution of low ionic strength, in which the protein and neutral polysaccharide remain in the solution, and in a solution of high ionic strength, can form a complex with the protein and most other polysaccharides other than acidic polysaccharides, but cannot precipitate the nucleic acid, thus separating the nucleic acid.

How to use:

1. Extract DNA formula:

CTAB 4g

NaCl 16.364 g

1M Tris-HCl 20 mL(PH8.0)

After cooling, 0.2-1% 2-mercaptoethanol (400ul) chloroform-isoamyl alcohol (24:1) : first add 96ml chloroform, then add 4ml isoamyl alcohol, shake well.

2. Extract the RNA formula

2% CTAB (W/V)

2% polyvinylpyrrolidone (W/V)

100 mM Tris-HCl (pH8.0,DEPC treated water formulation)

25mM EDTA

Since Tris-HCl reacts with DEPC under high temperature sterilization conditions, the RNA extraction buffer is directly treated with DEPC water.

Use/Application:

It is used to prepare purified DNA from organisms that produce mucopolysaccharides in large quantities, such as plants, and from certain Gram-negative bacteria, including certain strains of E.coli.

Precaution:

It is irritating and harmful if inhaled, ingested or absorbed through the skin. Wear proper gloves and protective glasses when using (or operating in a fume hood). Avoid inhaling its dust.
