The specific protein analyzer uses scattering turbidimetry to determine the reaction between antigens and antibodies, and the rate method is used during the measurement process. Compared to other measurement methods, this method has higher sensitivity and faster detection speed, and is not affected by background scattering signals. Specific protein analyzer is mainly used to measure the content and activity of specific protein molecules in biological samples such as serum and plasma, and the interaction between these protein molecules and other molecules (such as antibodies and ligands). It can be used to detect tumor markers, infectious diseases markers, cardiovascular disease markers, etc., and dynamically monitor the content and change trend of these markers, Improve early diagnosis of diseases and assess treatment outcomes. In addition, specific protein analyzers can also be used for drug screening and efficacy evaluation research.
