Principle of ELISA test
Enzyme-linked immunosorbent assay (ELISA) is an enzyme-labeled solid-phase immunoassay technology. The basic principle is to bind the antigen (or antibody) to the solid-phase carrier, convert the antigen (or antibody) and a certain enzyme into an enzyme-labeled antigen (or antibody). During the detection, the sample to be tested and the enzyme-labeled antigen (or antibody) are reactedRead more

Discussion on the Quality of Organs in the Safety Evaluation of Preclinical Drugs
The evaluation of organ quality in toxicity studies is an important part of the evaluation of drugs, compounds and medical devices. The American Society of Toxicology and Pathology (STP) has made corresponding guidelines and recommendations for organ weighing in general toxicity studies, and detailed the value of weighing data for major organs in special systemsRead more

What information will the IND review evaluate?
☆Background information for registration application The background information to be considered in an IND application mainly includes four parts: the structural source of the compound, the pharmacological classification, the current status of research/marketing of similar drugs at home and abroad, and the basic status of the application project. Among them, the structure source mainly analyzesRead more

FDA's IND application strategy
An Investigational New Drug Application (IND) is the US FDA's approval for drugs that have not yet been approved for marketing and require clinical trials. In addition, the U.S. federal government prohibits intercontinental transportation and distribution of drugs that have not been approved by the FDA in the U.S. Therefore, for sponsors to transport drugsRead more

Talking about IND application
The research and development of new drugs is a systematic project that encompasses the joint efforts of multiple disciplines, the collaboration of multiple departments, and the completion of the "dream”. However, due to the high-risk characteristics of the R&D process, even if everything is devoted to each link, it may not be able to bearRead more

LC-MS/MS for Quantitative Analysis
After a century of development, LC-MS/MS has become more and more widely used in various fields such as medicine, food, environment, forensic medicine, and clinical medicine. Especially suitable for clinical testing, the scope of application far exceeds the scope of radioimmunoassay and chemical testing, which is unmatched by other methods. LC-MS/MS has the characteristics ofRead more

Understand the Difference Between LC-MS and LC-MS/MS
LC-MS can obtain total ion chromatograms by collecting mass spectra. Because electrospray is a soft ionization source, there are usually few or no fragments. There are only quasi-molecular ions in the spectrum, so it can only provide molecular weight information of unknown compounds, not structural information. It is difficult to use for qualitative analysis, butRead more
