Biomarker detection includes cAMP detection and cytokine (TNFα, IL6) detection. cAMP detection is helpful for further exploring the mechanism of cell signal transduction and better understanding the regulatory process of cell physiological functions. Cytokine detection is an indispensable part in the process of drug research and development. It helps to determine whether a drug has anti - inflammatory, immunomodulatory or anti - tumor effects and evaluate its toxicity.
