Based on more than 20 years of experience in rodent modeling, Beijing Vitalstar has mature surgical techniques and standardized drug induction procedures. According to the needs of researchers, we can develop customized services for surgical modeling. According to the characteristics of the disease studied, physical and chemical induction methods such as physical (such as mechanical, light, electricity, radiation, etc.) and chemical (drugs, chemical reagents, etc.) are used to treat animals to obtain disease models.
