Usage Guidelines
- Dissolve CTAB in distilled water or appropriate buffer solutions before use.
- For DNA extraction, use CTAB with sodium chloride to selectively precipitate nucleic acids while removing contaminants.
- For nanoparticle synthesis, prepare CTAB micellar solutions to act as a stabilizing agent.
- Handle with care as CTAB is a cationic surfactant that may cause irritation upon contact with skin or mucous membranes.
