A recently developed assay, the surrogate virus-neutralization test (sVNT) is a quick and commercially available alternative to the 'gold standard' virus neutralization assay using authentic virus, and does not require processing at BSL-3 level. The development and validation of this surrogate virus neutralization test assay have previously been reported . hybridoma) or in vitro methodologies such as phage display. The surrogate virus neutralization test or cPass differs from other commercially available kits because it allows rapid detection of neutralizing antibodies (NAbs) - the specific antibodies . A "surrogate" virus neutralization test (sVNT ) that can be done in BSL-2 containment has recently been reported [8]. The surrogate virus neutralization test or cPass differs from other commercially available kits because it allows rapid detection of neutralizing antibodies (NAbs) - the specific antibodies present in the serum of COVID-19 patients that are responsible for clearing the viral infection. This is a list of supplementary files associated with this preprint. Recent studies demonstrated that the cPass test does not detect binding antibodies such as those typically detected in conventional indirect ELISA tests, but rather the presence of neutralizing antibodies.4 The remaining reagents can be stored at 4C. It does this by measuring the activity of neutralizing antibodies to SARSCoV-2. The current gold standard is a virus neuralization test (VNT) requiring live virus and a biosafety level 3 (BSL3) laboratory. The test works according to the principle of competitive binding between a purified antibody and HRP-labeled human ACE2 (angiotensin-converting enzyme 2), which is the natural ligand of the receptor-binding domain (RBD) in the COVID-19 pathology.

This publication contains a number of papers which consider the public health role of vaccines in improving the health of the world's populations, and looks at the challenges of using immunisation to combat emerging and re-emerging diseases On the contrary, in the presence of unspecific antibodies (Abs) the formation of the HRT-ACE2-RBD complex takes place leading to an intense signal. According to a preprint of a study focusing on cPass, the new test, which is a surrogate virus neutralization test, can detect neutralizing antibodies without the "need to use any live virus or cells and can be completed in one to two hours" in most research or clinical labs. A team of international scientists has recently evaluated a surrogate virus neutralization test for severe acute respiratory coronavirus 2 (SARS-CoV-2) and observed that it is highly efficacious . This book provides a comprehensive review of the major barriers to HIV cure and vaccine. We compared the results of three chemiluminescent immunoassays (CLIAs) (Abbott, Roche, Siemens) and a surrogate virus neutralization test (sVNT, GenScript) using 191 sequential samples from 32 COVID-19 patients. Viruses. Diagnostic Efficiency of Three Fully Automated Serology Assays and Their Correlation with a Novel Surrogate Virus Neutralization Test in Symptomatic and Asymptomatic SARS-COV-2 Individuals .
