What are the types of specific chemiluminescence immunoassays? Chemiluminescence immunoassay is a new stage in the development of immunoassay. Before this, it also experienced radioimmunoassay, fluorescent immunoassay, enzyme-labeled immunoassay and other different periods. However, the current chemiluminescence immunoassay tests environmental protection, rapid, accurate, etc. Etc. Because of these advantages, the w22sipl chemiluminescence detector will become more and more popular. It has high sensitivity, strong specificity, low reagent cost, stable reagent and long effective period.
The demand for domestic chemiluminescence detectors is increasing, which has attracted the attention of many medical device manufacturers. Nowadays, more and more domestic medical device companies have begun to develop and produce. Semi-automatic PHX-2012 domestic chemiluminescence detector, the equipment is developed and produced by the domestic Prang Medical Institute, cost-effective, after-sales and maintenance is also good. What are the types of specific chemiluminescence immunoassays?
1. Direct chemiluminescence: an antibody labeled with an acridinium ester (antigen), which is oxidized by H2O2 under alkaline conditions (NaOH), emits light having a wavelength of 470 nm, has a high luminous efficiency, and its excited state product N-A Acridine is an illuminant of the luminescent reaction system.
2. Electrochemiluminescence (ECLIA): an electrochemiluminescent agent, a pyridinium-labeled antibody (antigen), a tripropylamine (TPA) as an electron donor, and a specific chemiluminescence reaction in the electric field due to electron transfer. It consists of two processes, electrochemical and chemiluminescence, that emit light at a wavelength of 620 nm.
3. Enzymatic reaction Luminescence: It is the catalysis of a labeling enzyme to illuminate a luminescent agent (substrate). This kind of luminescent agent that needs to be catalyzed by an enzyme is called an enzymatic reaction luminescent agent.
The PHX-2012 semi-automatic chemiluminescence immunoassay analyzer produced by Prang Medical Equipment Co., Ltd., a brand of chemiluminescence immunoassay analyzer, is developed and produced by Prang Medical's Beijing Prang New Technology Co., Ltd., which uses Windows operating system and has detection. The project parameter setting function has high sensitivity, strong specificity, low reagent cost, stable reagent and long effective period. Welcome to call 400-6656-888
PHX-2012 semi-automatic chemiluminescence immunoassay analyzer features:
1. Because chemiluminescence immunoassay does not use any light source, it avoids the interference of background light and stray light, reduces noise, and greatly improves the signal-to-noise ratio. Therefore, special chemiluminescence immunoassay analyzers generally have high sensitivity, usually The nanogram chemical composition can be determined.
2. Measure the chemiluminescence intensity, use a photoelectric conversion device, and record the relative intensity of chemiluminescence with a function recorder or a digital display device. The concentration of the component to be tested is quantified by the maximum luminous intensity (peak height of the curve).
3. Flow injection chemiluminescence is also widely used due to the development of flow injection analysis (FIA) technology.
4. Equipped with a microcomputer system, automatic injection, storage of records, printing results, making chemiluminescence analysis faster.
