Fapon Biotech new reagent raw materials and test components for the latex-enhanced immunoturbidimetric platform is now added to the COVID-19/SARS-CoV-2 Neutralizing Antibody Test Solution. Products for ELISA, CLIA and CMIA, had introduced earlier in supporting customers’ NAb test development and vaccine effectiveness evaluation. With the company mission, ‘Enable Earlier Disease Identification, More Convenient, Accurate and Affordable Diagnosis’, continues to illuminate each action made during the pandemic, Fapon Biotech seeks ongoing innovations to support pandemic diagnosis and control.
Current Challenge in Vaccine Effectiveness Evaluation
The current gold standard method uses the live virus neutralization model for NAb detection in vaccine clinical trials, which requires BSL3 laboratory cultivation and can not be applied as a large-scale conventional testing method. Although a BSL3 laboratory does not require in alternative methods pseudovirus-based and GFP/Luciferase gene reporter system, the detection time that takes 3 to 5 days also sets the limit on their application as large-scale conventional tests.
Fapon Biotech COVID-19 NAb Test Solution
Fapon Biotech COVID-19 NAb Test Solution provides alternative testing methods to gold standard live virus-based PRNT with high correlation in performances, solving the problems of requiring high laboratory safety level, long detection time and quantification. Similar products are launched previously for the application of ELISA, CLIA and CMIA platforms (http://bit.ly/3d0QIBb). New products for Latex-Enhanced Immunotrurbidimetry platform are further introduced to diversify the Fapon Biotech COVID-19 NAb Test Solution, offering more options to develop high-throughput, accurate and convenient NAb commercial test kits.Fapon Biotech COVID-19 NAb Test Solution for Latex-Enhanced Immunoturbidimetry
