Acute Toxicity Test / Repeated Dosing Screening Test Acute toxicity evaluation is one of the basic types of in vivo safety evaluation. Drug registration often requires acute toxicity evaluation. Acute toxicity test data has a special role in safety evaluation, and MTD or MFD can be determined in the initial toxicity description. The data obtainedRead more

Drug safety evaluation plays an extremely important role in the drug development process. As some non-cardiovascular drugs have been found to induce acquired QT prolonged syndrome (LQTS), leading to severe arrhythmia (Torsade de Pointes) , TdP) and after withdrawing from the market, the safety evaluation of the drug on the heart becomes extremely important. TheRead more

The research and development of innovative drugs is a long-term process with high investment, high risk and high return. It takes more than ten years on average from early discovery to successful listing, and the cost is as high as more than 1 billion US dollars. Pharmacokinetics (DMPK) research runs through all stages of leadRead more

The competitive ELISA format is based on the binding competition in the initial insulin RIA and IgG EIA methods. The competition between the target analyte from the sample and the reference analyte and the binding of the analyte-specific antibody is the key to this format. Either antibody or target analyte can be labeled with enzymeRead more

All you need to know about the ELISA experiment is here. ELISA, the full name of enzyme-linked immunosorbent assay, is a commonly used immunoassay method; Detection Principle The known antigen or antibody is adsorbed on the surface of the solid phase carrier, the antigen or antibody is labeled with enzyme, and the antigen or antibodyRead more
