سی تب-CTAB- ستیل تری متیل آمونیوم بروماید

CTAB may refer to:

• Cetyl trimethylammonium bromide, an antiseptic agent
• Chemical table file, a data file type used in chemoinformatics
• The Canadian Technology Accreditation Board, an accreditation board for post-secondary technology programs
• "Lungs Clear To Auscultation Bilaterally", an abbreviation used in medical records for lung examination,
• also used in DNA extraction.
• A community of people engaged in investments in fixed-odds betting.

the presence of polysaccharides in a DNA preparation can inhibit use of techniques such as polymerase chain reaction (PCR). Cetyltrimethyl ammonium bromide (CTAB) is a surfactant useful for isolation of DNA from tissues containing high amounts of polysaccharides. Under the high-salt conditions used in this protocol, the CTAB binds the polysaccharides, removing them from the solution. When used with Arabidopsis, this procedure yields quite pure DNA that is suitable for thermal asymmetric interlaced PCR (TAIL-PCR).
