CTAB DNA extraction buffer for plant DNA extraction

Modified CTAB Method for High Quality Genomic DNA

According to Demeke et al. ( ), CTAB extraction method is better than Wizdar extraction and DNeasy Plant Mini Kit, as it produces large quantity of DNA. Moreover CTAB extracted DNA has less ratios of Abs (Absorbance) 260/280 and Abs260/230 indicating the purity of DNA, but this method has need of more modifications.

Miniprep Protocol for High Quality DNA Extraction from Plants

CTAB ([(C 16 H 33)N(CH 3) 3]Br, FW 364.45 g/mol) is a cationic detergent used in the DNA extraction buffer to remove membrane lipids and causes cell lysis. CTAB binds to the polysaccharides in high salt concentration condition (generally NaCl is used for this purpose), thus it removes polysaccharides from solution.

CTAB Protocol for the Isolation of DNA from Plant Tissues

The following protocols for isolating clean plant DNA, both start with a traditional approach using a cetyltrimethylammonium bromide (CTAB) buffer. At that point they diverge, the first protocol makes use of phenol and chloroform, and the second protocol uses a reverse solid phase extraction (i.e., capturing contaminants on a solid phase).

CTAB Extraction Buffer (Refer General Preparation Instructions). Mix gently by inversion. NOTE: Ensure that CTAB powder and - mercaptoethanol is added to CTAB Extraction Buffer prior to use. DNA can be extracted from fresh plant tissue by grinding a leaf or leaf disc in a small amount of Extraction Buffer. 2.

The Basics of DNA Extraction - Alaska BioPREP Virtual Textbook

The three basic steps of DNA extraction are 1) lysis, 2) precipitation, and 3) purification. Step 1: Lysis. In this step, the cell and the nucleus are broken open to release the DNA inside and there are two ways to do this. First, mechanical disruption breaks open the cells. This can be done with a tissue homogenizer (like a small blender

A Simple Method for DNA Extraction from Mature Date Palm

highly versatile cetyl trimethylammonium bromide (CTAB) method has been used for the extraction of DNA from various plant materials [4]. There are three main contaminants associated with plant DNA that can cause considerable difficulties when conducting PCR experiments: polyphenolic compounds, polysaccharides and RNA.

CTAB buffer' suffer from low capacity of DNA extraction, but it also extracts lower concentration of impurities. 'SDS buffer' can extract DNA more efficiently that CTAB buffer. The protocol of DNA extraction with these buffers is the same as the protocol with modified PVPP buffer, except that PCI treatment do not need to be repeated

1. Introduction. Plants produce secondary metabolites that interfere not only with extraction of high quality genomic DNA but also with the subsequent reactions such as PCR and related genetic analyses (Kotchoni and Gachomo, , Kotchoni et al., ).The widely used genomic DNA extraction procedures rely on lengthy protocols that use hazardous chemicals or expensive commercially available kits.

DNA yields, as quantified using Hoechst 33258 dye fluorometry, are typically between land 50!!g depending on species, starting material and extraction conditions mentioned earlier. This represents enough DNA for between 40 and 2000 RAPD PCRs.

Robust CTAB-activated charcoal protocol for plant DNA

DNA extracted from plants rich in polyphenols and/or polysaccharides is often problematic when subjected to polymerase chain reaction, especially when ma ture tissues are used for DNA extraction. In order to overcome the problems associated with poor-quality DNA extracted from such plant samples, a protocol has been developed, availing on a high salt concentration and on the combination of
