One-Tube Tissue DNA Extraction Kit: The kit is designed for rapid isolation of genomic DNA from animal tissue, mouse tail and ear clips, human hair or saliva, fish and insect tissues.There is no need for phenol extraction, overnight digestion, DNA precipitation or column purification; the lysate can be used directly as PCR template. The one-tube procedure minimizes possibility of cross-contaminations between samples. the whole procedure takes less than 15 minutes and this kit is an example of speed and efficiency. The kit is suitable for high throughout PCR screening of large scale samples. This kit also works for other application such as Genotyping, Transgene screening, Knockout analysis and sequencing.
