Introduction
Capillary electrophoresis reagent consumables are special reagent consumables used for forensic science DNA electrophoresis detection. They are used in conjunction with special genetic analyzers.
It plays a vital role in the accurate typing of DNA fragments such as STR loci, including various products such as separation gel, formamide and buffer.
Taste. In order to ensure that the basis used in the development, production, and testing of related products is practical, feasible, and standardized, a series of standards have been formulated. GA/T 2091
