Problems solved by technology

The above-mentioned quality control products use human seminal plasma as the matrix, which has the disadvantages of limited raw material sources, potential biological safety hazards, and poor stability. At the same time, the storage time of this seminal plasma quality control product is short, which is not conducive to the detection of reserved samples and long-distance transportation

Description

technical field [0001] The invention belongs to the technical field of in vitro detection reagents, and relates to a seminal plasma biochemical quality control product and a preparation method thereof. Background technique [0002] There has been a lack of experimental quality control materials for the detection of biochemical indicators in semen, which makes the standardization of semen biochemical analysis stagnant. Many substances in semen are unstable in vitro and difficult to preserve, which increases the technical difficulty of preparing seminal plasma quality control products. In order to solve the problem of semen quality control products, the patent application number CN201410145716.0 provides a seminal plasma composite quality control product with seminal plasma as the substrate. In this application, the seminal plasma composite quality control product consists of quality control product preservation solution The freeze-dried powder made by mixing with the seminal...
