Host cell residual DNA refers to the small amount of nucleic acid (host genome, plasmid, or total DNA) that remains in protein drugs expressed and purified through cell culture. During the production process of expressing antibody protein drugs, a large number of cells undergo proliferation and amplification, and some aging cells die and lyse, releasing a large amount of genomic DNA. This leads to the presence of a large amount of free host cell DNA in the cell culture harvest of recombinant biologics, and a small part of the host cell DNA is removed during the processing steps (such as acid precipitation, filtration, etc.), while most of it is removed during the anion exchange chromatography step. Finally, there is a trace amount of host cell residual DNA in the original solution of the recombinant protein drug.

HH-H0019-1 HEK293 Host Cell Protein Assay Kit, G2-96T HEK 293 Host Cell Protein ELISA Kit, G2 is for research use only, it should not be used in clinical diagnostic procedures. The kit is intended for the quantitative determination of residual host cell protein in Cell Culture Supernatants, Protein Purification Process, and End-Product expressed by HEK 293 expression systems.

A hamster is also known as suslik, which is an animal domesticated by wild animals and entered the laboratory. There are 8 kinds of hamsters for experimental research. There are mainly two kinds of hamsters as experimental animals: Golden hamster, Mesometritus auratus and Chinese hamster, Crucetulus griseus. Among them, the Chinese hamsters are widely used in nutrition and infectious disease research. In addition, the Chinese hamsters are often used for the study of diabetes, and they are good animal models of true diabetes.

Fish are often used in environmental monitoring, embryo research, tumor research and others. Among them, zebrafish is the most commonly used. The zebrafish is a common tropical fish, which is native to South Asia. The zebrafish have a slender body with an adult length of 3~4cm, and they do not require high water quality. About 3 months after hatching, the fish reach sexual maturity, and mature fish can lay eggs every few days. The eggs are fertilized in vitro and develop in vitro. The embryo development is synchronous and fast, and the embryo body is transparent.
