A02087, SARS-CoV-2 Neutralizing Antibody Standard, is intended for the calibration of the semi-quantitative assay of SARS-CoV-2 Surrogate Virus Neutralization Test. Research Applications COVID-19 Diagnostic Test
The semi-quantitative analysis method was introduced for lesion and its distribution area. Results The ground-glass opacities (GGO) and mixed GGO with consolidation were the most frequent features found. Consolidation followed, and the appearance of stripes which showed an increasing trend before the...
COVID-19 Neutralizing Antibody ELISA Kit, KA6111, highly specific and rigorously validated in-house for Semi-Quantification. COVID-19 Neutralizing Antibody ELISA Kit is an indirect enzyme-linked immunoassay (ELISA) for semi-quantitative determination of
Initially, semi-quantitative assays such as gel electrophoresis and Western blot are accepted to show the transgene expression of viral vectored vaccines, although for late-stage clinical trials and licensure more quantitative methods will be required to assess potency. A variety of methods may be app...
We used a semiquantitative ELISA for IgG based on the SARS-CoV-2 S1 spike protein domain/receptor binding domain (Euroimmun, Lübeck, Germany) for primary testing. For additional secondary analyses in all baseline samples, positive controls, and positive or equivocal positive sera, an anti-SARS-...
A semi-quantitative test that provides three measures of neutralizing antibody levels — low, medium and high; And a qualitative test that provides yes/no results indicating whether the number of neutralizing antibodies is likely to provide immunity from contracting the virus ha...
b Semi-quantitative measurements. Data points represent individual participants, boxes denote interquartile range, horizontal line represent the median, and whiskers denote the minimum and maximum values below or above the median at 1.5 times the interquartile range. Note the y scale differs for the...
Point-of-care (POC) quantification of antibody responses against SARS-CoV-2 spike protein can enable decentralized monitoring of immune responses after infection or vaccination. We evaluated a novel POC microfluidic cartridge-based device (ViroTrack Sero COVID-19 Total Ab) for quantitative detection ...

e, f pDCs were cocultured with infected cells, either in direct contact [coculture] or physically separated by the semi-permeable membrane of transwell [TW], or treated with SN from the corresponding SARS-CoV-2-infected cells. IFN-α concentration was also determined in the SN of SARS-CoV...
