Microbiology test kit

plasmaurine

【Intended use】 　　Death of tumor cells will release its DNA fragments into the blood, the blood of the cell-free circulating DNA can also be through the kidney filter into the urine. 　　The kit used a double column to extract cell-free circulating DNA from 200 ml of urine, or 10 ml of plasma. 　　The method is fast and simple, and does not need to contact with a strong organic solvents (phenol and chloroform), the operation can be completed in a short time. 【Product performance】 　　Sample volume: 200 ml urine, or 10 ml plasma. 　　DNA purity: used directly for nucleic acid amplification. 　　DNA size: mainly in the range of 100 to 500 bp, and large fragments of DNA from cell residues will remain on the membrane. 　　DNA recovery: ≥ 90% in the range of 100 ~ 500bp. 　　Column capacity: 20 μg. 【Principle】 　　The double column comprises a DEAE membrane used as a concentrator and a silica film used as a purifier. 【Advantages】 　　1. Particularly suitable for volume samples, such as 200ml urine. 　　2.High DNA recovery rate (150 ~ 250bp). 　　3.Directly applied to downstream detection, such as PAP and PCR.
