Principle
This product is based on silica column purification. The sample is lysed and digested with lysate and protease, DNA is released into the lysate. Transfer to an adsorption column. Nucleic acid is adsorbed on the membrane, while protein is not adsorbed and is removed with filtration. After washing proteins and other impurities, Nucleic acid was finally eluted with low-salt buffer (10mm Tris, pH9.0, 0.5mm EDTA).
Advantages
High quality DNA – meet a variety of downstream applications, including PCR, qPCR, enzyme digestion, hybridization, etc.
Fast – without separation of leukocytes, organic extraction or ethanol precipitation
Simple – all nucleic acids can be obtained by direct digestion
Pertinence – specially designed for isolating DNA from 3-10ml blood and related body fluids
Wide applicability – handle a variety of liquid samples
Proteinase K, RNase A should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15-25°C) and are stable for at least 18 months under these conditions.
*Note:Leukocyte protocol can be used when large volume whole blood samples need to be processed. Whole blood was treated with red blood cell lysate, and white blood cells were obtained by centrifugation before extraction
