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.

When DNA has to be isolated from cells, CTAB is used to facilitate in the lysis of cells so DNA can be released into the bulk of the solution, from where is it is isolated through further steps.

Role of ctab in isolating DNA from soil sample?
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.
What is the principle involved in the isolation procedure?
DNA isolation is a based on the principle of purification. DNA samples are isolated through the use of physical and chemical methods. Friedrich Miescher conducted the first isolation of DNA in 1869.
What is the importance of ctab buffer?
importance of ctab buffer
Why 70 percent alcohol and absolute alcohol used in DNA isolation?
70% ethnol is used for the dna isolation becuse it makes hydrogen bonding with the water molecules and makes DNA hydrophopic so that it pricipitated.
Why you use TEG Buffer in isolation of plasmid DNA?
Good morning, the TEG contains TRIS to keep pH of solution constant, EDTA to capture ions Ca2+ and Mg2+ in solution (which may interfere in the isolation of DNA) and Glicose/Dextrose (+- 50 mM) is used to increase the osmolarity of solution and lysin the cell. the cell swells to bursting and the DNA remains in solution.
What does ctab use for isolation of DNA from animal blood?
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.
Role of CTAB in DNA isolation?
It sequester carbohydrates in the solution
What materials do scientists typically use when extracting DNA?
phenol,chloroform,isoamyl alcohol,ethanol,CTAB reagent,Na acetate etc.. but nowadays, they use kits for any kind of DNA isolation, which makes their job easier.

Isolation of genomic DNA from groundnut leaves?
Hello, Its very simple, u can go for the CTAB method , with bit modification, 1) Ensure the youngest possible leaves, very tender enough to crush. 2) Crush the leaf sample in liquid nitrogen. 3) add quickly CTAB buffer to the crushed isolate immediately. 4) the follow Rapid method of isolation.
Use of agrose in DNA isolation?
Agarose is not used in DNA isolation. Agarose is used to prepare a gel in which DNA fragments can be separated based on size
What is the principle involved in the isolation procedure?
DNA isolation is a based on the principle of purification. DNA samples are isolated through the use of physical and chemical methods. Friedrich Miescher conducted the first isolation of DNA in 1869.
What is CTAb?
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
Why use chloroform in DNA isolation?
DNA is soluble in chloroform more than water. So we use it.
What is the difference between CTAB and SDS method?
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
Why did we use a salt in the DNA extraction solution?
To provide ionic strength,neutralise DNA,etc.
