Abstract

The invention discloses a kit and method for extracting collybia radicata genome DNA (Deoxyribonucleic Acid). The kit is prepared from the following components: an equilibrium liquid including 1 percent of Na2SiO3.9H2O and 1 percent of NaOH, lysate including 5.0M of guanidine hydrochloride, 25 percent of isopropanol and 1 percent of PVP K30, a cleaning solution including 20 mM of NaCl, 20 mM of Tris-HCl and 85 percent of ethanol with pH of 7.5, eluent including 10 mM of Tris-HCl with the pH of 8.5 and a DNA adsorption column. The reagent for extracting the collybia radicata genome DNA does notcontain toxic substances such as phenol and chloroform, so that higher safety is realized; the extraction method is simple and efficient and the extraction time is shortened to 15 minutes; an extracted product has high purity and good integrity, and can be directly used for molecular biology and genetic research.

Description

technical field [0001] The invention belongs to the technical field of molecular biology, and in particular relates to a kit and a method for extracting the genomic DNA of Rhizome lanceolata. Background technique [0002] DNA is the carrier of genetic information in living organisms, including the genetic traits of organisms. High-quality, high-purity total DNA is the primary condition to ensure the development of molecular biology research such as PCR amplification, restriction endonuclease digestion, genetic map analysis, molecular hybridization, genetic diversity analysis, and genomics. Therefore, it is extremely important to efficiently and rapidly prepare total DNA samples with high purity and good integrity. [0003] At present, the traditional methods for preparing fungal total DNA include CTAB method, SDS method, alkali lysis method and conventional kit method, etc. CTAB method and SDS method use ionic surfactants to lyse fungal cells to release the genome, and then...
