32. According to this feature, we used magnetic beads coated with ConA, a plant lectin that can specifically bind glycoproteins, to capture the SARS-CoV-2 virions prepared from the supernatants of infected Vero cells (see “Methods”). After capturing the...
Titer determination of infective SARS-CoV-2 virions was performed by plaque assay on VeroE6 cells (ATCC, Manassas, VA, Number CRL-1586). VeroE6 were infected with serial dilutions of the cell supernatants collected at different time points post infection. After 1 h virus absorption, the co...
“There is no evidence that mosquitoes can acquire and transmit the SARS-CoV-2 virus,” he toldMNT. In order to understand the mechanisms that prevent mosquitoes from carrying and spreading the SARS-CoV-2 virus, Dr. Markowski explained it is important to understand how mosquitoes transmitvirion...
Evaluation of safety and immunogenicity of an adjuvanted, TH-1 skewed, whole virion InactivatedSARS-CoV-2 vaccine - BBV152 bioRxiv (2020) p. 2020.09.09.285445 Google Scholar [138] P. Yadav, et al. Remarkable Immunogenicity and Protective Efficacy of BBV152, an Inactivated SARS-CoV-2 Vaccine ...
cells. However, only a single full-length +gRNA, but not sgRNAs, is needed for virion assembly. What is the driving force behind the specific selection of the full-length +gRNA from a mixed pool of +/−gRNAs and +/−sgRNAs, allowing a full-length +gRNA assemble into a virion?
, viral assembly, morphogenesis, and release of virion particles from the host cell [43]. The function and expression of accessory proteins are still largely unknown. Considerable genomes from all parts of the world have been sequenced and are available at the Global Initiative on Sharing All ...
NAbs are crucial for virus clearance and to achieve protection against SARS-CoV-2 [23]. They may achieve this in several ways—including interfering with virion binding to receptors, blocking virus uptake into host cells, and preventing uncoating of viral genomes in endosome or causing aggregation...
virion control (RCAS) was spiked into each sample and quantified to determine the efficiency of RNA extraction and qPCR amplification37. Concurrent analysis of results by this CDC N1 viral load assay showed high correlation with that of the Roche cobas SARS-CoV-2 ORF-1ab and E genes (...
SARS-CoV-2 virions have been reported to remain stable and infectious in aerosol for up to 3 hours10; therefore, microwaves with specific frequencies could potentially be used to inactivate SARS-CoV-2 under reasonable microwave power densities that are safe for the human body. Various devices ...
