CTAB–NaCl Solution

1. Wearing gloves, dissolve 4.1 g NaCl in 80 mL of H₂O.

2. Slowly add 10 g of CTAB (hexadecyltrimethyl ammonium bromide) while heating and stirring.

   • If necessary, heat to 65°C to dissolve.

3. Adjust the final volume to 100 mL for final concentrations of 10% CTAB and 0.7 m NaCl.

4. Store at room temperature.

   • The solution is stable for several months.
