Microplate Reader(MicroplateReader)It's for enzyme-linked immunosorbent assayELISAProfessional instruments for reading and analyzing experimental results. Enzyme linked immunosorbent assay (ELISA) is a reaction performed by catalyzing a chromogenic substrate coupled to an antigen or antibody. The result is displayed in color, and the concentration of the antibody or antigen to be tested in the specimen can be determined by the intensity of the color, i.e., the absorbance value.

Enzyme linked immunosorbent assay (ELISA) is widely used in clinical testing, biological research, agricultural science, food and environmental science, especially in recent years,Due to the widespread use of enzyme-linked immunosorbent assay (ELISA) kits, enzyme-linked immunosorbent assay (ELISA) has become increasingly popular in the field of reproductive health, while also promoting the improvement of reproductive health technology.

At present, many domestic family planning stations have carried out enzyme immunoassay projects, such as: five items of hepatitis B, AIDS detection, and eugenicsSeries testing, hormone testing, etc. In the past, most methods used visual inspection, and the results reported lacked scientific basis. For example, a certain bowThe critical value specified in the worm detection kit is the negative control substanceODValue x2.5It is impossible to determine the specimen well by visual inspectionReflect whether the color exceeds the critical value. Comparing the color between two holes with the naked eye may be acceptable, but comparing the color of one hole is not necessaryBeyond the color of another hole2.5Doubling is impossible. Several domestic institutions, such as the Clinical Laboratory Center of the Ministry of Health and the Family Planning System, have repeatedly emphasized the importance of enzyme-linked immunosorbent assay (ELISA) and requested that ELISA reagents be interpreted using an ELISA reader. The quality control of ELISA reagents should also use an ELISA reader and provide the original data measured by the ELISA reader. However, the instructions for each manufacturer's reagent kit do not require visual inspection. At the same time, the items of enzyme immunoassay are often some substantive infections and diseases, such as hepatitis, AIDS, eugenics, etc. The interpretation is more rigorous. It is difficult to deal with disputes caused by misdiagnosis. In addition, preoperative symptoms such as hepatitis C and HIV in hospitalized surgical patientsEIAReagent testing is a necessary means to avoid medical accidents and disputes caused by infections caused by blood transfusions, and is gradually being adopted by many units.

There are three main methods for immunodiagnosis in China: enzyme immunoassay（EIA）Release exemption（RIA）And shine, the sentiment in the marketThe situation is as follows: the market cycle in which the method is located is the period of release and exemption from recession, Enzyme immunity enters the growth phase and luminescence enters the phase.Due to issues such as contamination and expiration dates of reagents, radiation exemption technology is gradually being phased out in the domestic market, while chemiluminescence reagents and equipment are relatively expensive, making their popularization in China, especially in the family planning system, take a long time,EIAThe technology is stable, the reagent prices are reasonable, and the supply is sufficient. Enzyme immunoassay technology is in the growth stage in the Chinese market, so it is appropriate to purchase an enzyme-linked immunosorbent assay (ELISA) reader.Especially noteworthy is the urgent need to equip China's family planning and maternal and child health care systems with enzyme-linked immunosorbent assay (ELISA) devices. What was earlierYears ago,The World Health Organization has recommended that pregnant women undergoTORCHFive routine screenings, but unfortunately due to the lack of equipment such as enzyme-linked immunosorbent assay (ELISA) and washing machines,RCHThe testing has not yet been widely carried out in China.TORCHInfection is referred to in perinatal medicine asTORCHSyndrome, due to pregnant women,Both fetuses and newborns are susceptible to infection,It has received great attention from obstetrics, gynecology, and pediatricsSee. Pregnancy infections not only harm the mother, but can also have serious effects on the fetus and newborn. Through the placenta, it can cause intrauterine infections leading to miscarriage, premature birth, stillbirth, or fetal growth retardation and malformation. Through the birth canal and breast milk, it can cause neonatal infections. If it affects the nervous system, it can cause varying degrees of intellectual disability, as well as various forms of paralysis and deafnessORCHThere is an extremely important relationship between infection and eugenics. ThereforeRCHTheIgGandgMThe examination is also commonly known as the ten tests for eugenics and fertility. currentlyTORCHThe main detection methods include radiation exemption（RIA）Enzyme immunity(EIA)Due to the need for special instruments and radiation hazards in the radiation immunization method, enzyme immunization is currently being used（EIA）Method replacement.EIAThe method has the advantages of strong specificity, high sensitivity, simplicity and speed, and low cost. As long as it is equipped with an enzyme-linked immunosorbent assay (ELISA) reader and other corresponding equipment, most ordinary laboratories can easily carry out it. Obviously,It is an urgent need to popularize enzyme-linked immunosorbent assay (ELISA) and other equipment in the family planning system as soon as possible. The implementation of this work will help to improve the level of diagnosis and treatment, reduce the incidence rate of mother and infant, and improve the health quality of the whole nation. Currently available in the marketEIAMore and more reagents are available:T3TheT4TheTSHTheTORCHSeries, infertility series, various cancer biomarkers, typhoid fever, paratyphoid fever, etc., as well as sexually transmitted diseases transmitted from mother to child(Such as gonorrhea, syphilisHIV)And hepatitis, such asHBVTheHCV)As well as fetal antibodies, newbornsTSHThere are also complete sets of vaccine response tests available in the marketEIASupply of reagent kits. The use of enzyme-linked immunosorbent assay (ELISA) is beneficial for expanding detection projects, improving detection levels, and achieving both social and economic benefits. Enzyme linked immunosorbent assay method, abbreviated as enzyme-linked immunosorbent assay,It is a type of marking technology,It is a sensitive technology developed from fluorescent antibody technology and isotope immunization technology,Unique,Fast and automated modern technology.
