The development of COVID-19 detection reagent was introduced. On February 4, the company decided to invest 3.8 million yuan to urgently start the independent development of COVID-19 detection reagent. On February 6, the R&D team of the company held a teleconference with Dr. Liu Huiyu, a researcher of the American HAMNER Research Institute and a senior expert in the pathogenesis research and treatment of infectious diseases in the United States, to determine the technical route of developing the novel coronavirus (2019 nCoV) IgM/IgG antibody detection kit (colloidal gold method), and immediately started the test preparation. On February 9, the company, together with the Institute of Life Sciences and Bioengineering of Beijing Jiaotong University, the First Affiliated Hospital of Anhui Medical University and other units, implemented the product development of COVID-19 detection reagent (ELISA). On February 16, the company resumed work smoothly and all tests were carried out in an orderly manner. After more than ten days of hard work, on February 26, the "novel coronavirus (SARS CoV-2) IgG/IgM antibody detection reagent (colloidal gold immunochromatography)" developed by the company made significant progress.
Through the comparison of experimental data, the positive detection rate of the company's products reached more than 90%, the detection time was 5-15 minutes, and all indicators met the requirements, marking that the main performance of the product was equivalent to the certified product. On February 27, the novel coronavirus (SARS CoV-2) IgG/IgM antibody test reagent (ELISA) developed by the company also passed the technical test, and all indicators were qualified, and was sent to the provincial CDC for sample testing, which was recognized by relevant experts.
Reviewing the war "epidemic" and the process of returning to work in the past month mainly depends on the scientific, orderly, active and effective prevention, control and safeguard measures of governments at all levels! I sincerely thank all departments of the municipal government, especially the Market Supervision Bureau, the Municipal Science and Technology Bureau, the Torch District Management Committee, the Industrial and Commercial Bank of China, the Health Base and other institutions, for their full support to the company in the process of resuming work and production!
We will continue to take various epidemic prevention measures, ensure the safety of employees, increase investment in technology development, accelerate the pace of developing new products, and actively fulfill the mission of bio-pharmaceutical enterprises and social responsibilities!

1、 Balance: Before operation, balance the reagent at room temperature for 30-60 minutes. 2、 Sampling: 1. The sample is serum: it is better to store the blood naturally for 1-2 hours, and then centrifuge with 3000 rmp for 15 minutes; 2. The sample is plasma: the blood sample collection tube containing anticoagulant must be used. After blood collection, the blood collection tube must be immediately inverted and mixed for 5-10 times. After a period of time, 3000 rmp centrifugation for 15 minutes; If it is detected within a few days, it can be placed in a refrigerator of 2-8 ℃; if it is to be stored, it can be placed in a low-temperature refrigerator of - 20 ℃; 3. After adding the sample, put it into the incubator in time. After adding the enzyme reagent, gently wipe the surface of the enzyme label plate with absorbent paper to absorb;MORE +
EB virus is an important DNA virus that infects human beings. There are many diseases related to EBV infection, especially nasopharyngeal carcinoma. With the development of modern molecular biology, the diagnosis of EBV infection has made rapid progress from principle to method. Due to the high operational requirements, expensive equipment and reagents, the application of pathogen detection is limited, so the immunoserological detection of EBV infection is the most commonly used method for NPC screening at present. The early diagnosis and clinical stage of NPC are of great significance to the curative effect of radiotherapy.MORE +
1. Sensitivity The sensitivity of a diagnostic reagent has two different meanings: first, the sensitivity represents that the reagent has the ability to detect the minimum amount of substances to be tested; Secondly, sensitivity also indicates the positive detection ability of the reagent in the population or a large number of samples, that is, the degree of false negative. Sensitivity is the primary quality standard of diagnostic reagents. If the sensitivity of the reagent does not meet the standard, then the reagent is worthless.MORE +
