Unlike traditional methods for plant DNA extraction (e.g., CTAB), Plant DNAzol® is quicker, does not require RNase A to remove RNA from genomic DNA preparations, and in the majority of tissues, does not require phenol. Furthermore, use of Plant DNAzol® generates yields from plant tissue that are comparable with the traditional CTAB …

CTAB DNA extraction buffer is more suitable for extracting DNA from the plant tissues. Because of the high content of the secondary metabolites, proteins, polysaccharides and polyphenolic compounds into the plant cell CTAB DNA extraction buffer is the first choice in the plant DNA extraction.

Jul 27, 2016· CTAB buffer is used to lyse plant cells in the same way SDS is used to lyse bacterial cells. They work in a similar fashion, apart from CTAB being a cationic detergent while SDS is anionic. …

DNA Extraction - CTAB Method We use this method for extracting genome sequencing quality (i.e. unsheared) DNA that can be used for large insert libraries. It was used to extract material for the Micromonas RCC299 complete genome sequencing project, and the Micromonas RCC472 genome sequencing project. This protocol originally came to us from Evelyne

Shaking too hard will shear the DNA. -Use any protocol for DNA precipitation, the one in this protocol works well. Reagent/Stock Preparation CTAB/NaCl (hexadecyltrimethyl ammonium bromide) Dissolve 4.1 g NaCl in 80 ml of water and slowly add 10 g CTAB while heating (≈65°C) and stirring. This takes more than 3 hrs to dissolve CTAB.

One of the most widely used detergents for plant DNA extraction buffers is CTAB (cetyltrimethyl-ammonium bromide). CTAB is most often used in a 2% (w/v) solution (Rogers & Bendich 1985, Doyle & Doyle 1987, Nickrent 1994).

CTAB methods have been applied in studies; however, the chemical forms complexes with DNA, making it critical that the correct concentration of CTAB is used to facilitate DNA extraction due to ability of the chemical to form complexes with DNA (Krishnaswamy, Pabst, Rappolt, Raghunathan, & Sood, 2006).

CTAB DNA Extraction Principle. isolation of DNA from Plant cell. Prepare CTAB buffer prior to starting extraction, add polyvinylpyrrolidone and b-mecaptoethanol. Ince these have been added the shelf life of the buffer is only 2-3 days. Preparation of CTAB buffer for DNA excretion
