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
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
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.

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.

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.
it means storage is full.
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.

There is a special bit signaling if the buffer is full. If the buffer is full the bit signals "BUSY" as result transmission stops until the bit changes to "READY" and transmission resumes.

A buffer in a computer is place where information is stored whilst being moved from one electronic device, to another. Or from on process to another. A buffer can only really get too 'full' if the information coming from one place overwrites the contents of the buffer, before the destination device or process reads it. That would occur if either device were to stop responding. In a computer program a buffer over flow can occur when the memory in a position near the buffer get's too full and information get's written to the buffer by mistake, this is known a Buffer Overflow the source of many software crashes and security vulnerabilities.
