Sample Preparation

Sample preparation in the field of life sciences is one of the key steps for successful experiments, and the requirements for sample preparation vary significantly among different research directions. Nucleic acid sample preparation refers to the process of extracting and purifying nucleic acids (DNA or RNA) from biological samples (such as blood, tissue, cells, saliva, swabs, environmental samples, etc.) that can be used for subsequent molecular biology experiments. It is a key prerequisite for experiments such as molecular detection, gene sequencing, PCR amplification, gene cloning, and gene expression analysis.
