APPLICATION OF PVP IN TOTAL DNA EXTRACTION IN MULBERRY
CTAB ( cetyltrimethyl ammonium bromide) buffer supplemented with 1% PVP (polyvinylpyrrolidone) was used to extract total DNA of mulberry with the method ofphenol- chloroform- isopentanol- endoribonucleases. Assay of the extracted DNA with martSpecTM3000(America)indicated that tlhe purity of the extracted DNA with PVP in CTAB buffer was very high,the value of A260/A280 being 1.80~ 1.90.The polyhexose,protein and RNA were eliminated completely.the extracted DNA can be used for AFLP.
