C-TAB is a detergent that helps lyse the cell membrane, however it is pretty poor with denaturing proteins so something with a longer tail is usually used for extraction.
CTAB is a buffer used in genetics to lyse (break down) the cell wall and membrane systems in a plant cell to allow DNA out of the nucleus so it can be studied. D-Train
CTAB is a detergent used to denature proteins from samples. Once the protens have been denatures, the isolation of DNA from the non required waste materials can begin.

hi, I work with CTAB extraction and I've noticed that is better to make the buffer without PVP and only add the PVP when you need the buffer. So I take 20ml CTAB and add 0.8mg PVP. Mix it and I use it not longer than 1 week. Hope this helps

plant cell lysis
The CTAB extraction procedure is from Rogers and Bendich (1986). The magic bullet is supposed to be the separation of polysaccharides from nucleic acids by the use of CTAB. The technique capitalizes on the previous observations that nucleic acids can be selectively precipitated with CTAB. RNA and DNA are soluble in CTAB and 0.7 M NaCl but precipitate when the salt is reduced below 0.4 M. However, many polysaccharides are insoluble over this salt range and are thus not solubilized. CTAB is NOT used to lyse membranes in this procedure.

CTAB is a surfactant used in the isolation of DNA from tissues containing high amounts of polysaccharides. Under the high-salt conditions of this protocol, CTAB binds the polysaccharides removing them from the solution. When combined with Arabidopsis, this procedure yields pure DNA.
It sequester carbohydrates in the solution
Often used to purified crude cell lysate by precipitating proteins, lipids and polysaccarides out of solution. This leaves only nucleic acid (DNA, RNA) in the supernatant.
importance of ctab buffer
This refers to the type of detergent used to lyse cell membranes when extracting DNA from cells. SDS=Sodium dodecyl sulfate, CTAB=Cetyl trimethylammonium bromide
In CTAB method,SEVAG is used to breakdown the tissues in the extracted leaves.While in dellaporta method,the SDS and POTASSIUM ACETATE are used.In CTAB method BLUECAP/TEST TUBES are used,while in dellaporta method the EMPENDORFS are mostly used.ICE COLD ETHANOL is used mostly in the CTAB method for resuspension,while in dellaporta method ISOPROPANOL is used.

CTAB is a cationic detergent. It is generally considered to be less denaturing than SDS. It is typically used when it is desired to maintain enzymatic activity. It is also typically used in protein refolding.
