β-actin gene is a kind of actin, in a variety of cells and tissues, β-actin gene expression is relatively stable [1], and β-actin gene in nuclear DNA has multiple copies, increased The detection rate of nuclear DNA [2], which is often used as an internal reference in PCR. In this experiment, the β-actin gene with good purity was obtained by PT-PCR, amplification, cloning, screening and PCR identification and restriction enzyme digestion of the RNA extracted from the mouse liver, which laid the foundation for the later experiment.

Objectives: To establish a simple, reliable, stable rat C6 glioma model, and to provide an operating platform for

studying the pathogenesis and prevention and treatment of glioma. Methods: C6 rat glioma cells were cultured in vitro and cultured in the right caudate putamen of SD rats. After implantation, the survival status of rats was observed and the pathological sections were made. HE is dyeing under light microscope. Results: After 6 days of inoculation of C6 glioma cells, the survival status was good at about 7 days, and the intracranial hypertension was more obvious at about 14 days. Most of them were in the endangered state. In the 18 specimens of the rats, except for the accidental death, the other tumor formation rate was 75%. The tumor structure was obviously displaced with the prolongation of the age of the tumor. HE staining was used to observe the formation of glioma in rat brain. Conclusion: The animal model of C6 glioma is reliable and stable. Its tumor growth characteristics and pathological features are similar to those of human glioma, which can be used as an ideal model for clinical study of glioma.
