Nucleic Acid Extraction Kit
The principle of nucleic acid extraction firstly ensures the integrity of the primary structure and secondly excludes the contamination of other molecules. Nucleic acid extraction should also simplify the steps, shorten the extraction time, and minimize the degradation of nucleic acid by external factors. Nucleic acid extraction is roughly divided into three parts: crushing, extraction, purification. Common sample extraction methods include solution extraction (concentrated salt, Trlzol), centrifugal column, magnetic bead method, etc.
