AURORA BIOLABS LLC SARS-CoV-2 PLpro Assay, 96 rxn
PLpro of Severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2 PLpro, also referred to as SARS-CoV-2 Papain-like protease, Nsp3) plays an essential role in processing the polyproteins 1ab for viral replication. Inhibition of this enzyme activity would block viral replication, making it a promising target for anti-coronaviral therapeutic agents. The assay is fast and convenient and requires just two steps. In the first step, the PLpro enzyme is preincubated with the compound for 30 minutes. The reaction is initiated by adding substrate solution at the second step. Fluorescent intensity is measured with a fluorescent plate reader at the excitation wavelengths of 340-360 nm and emission wavelengths of 460-480 nm.

ATILA BIOSYSTEMS INC iAMP COVID-19 Detection Kit
The iAMP COVID-19 Detection Kit is a real-time reverse transcription isothermal amplification test. The test is based on a proprietary isothermal amplification technology termed OMEGA amplification (Patent: WO 2017/205510 A1; publication: The Journal of Molecular Diagnostics, Vol.22, No 3, 419-428, 2020). OMEGA primer sets are designed to specifically detect RNA and later cDNA from the N and ORF-1ab genes of the SARS-CoV-2 virus in nasal, nasopharyngeal and/or oropharyngeal swabs from patients with signs and symptoms of infection who are suspected of COVID-19. The iAMP COVID-19 assay’s key differentiator from current rRT-PCR COVID-19 assays is its ability to detect SARS-CoV-2 RNA directly from samples without prior RNA extraction process. Swab specimens are inserted directly into our 1X iAMP COVID-19 Sample Buffer Mix with a 15 min incubation at room temperature and can be directly used for OMEGA isothermal amplification and signal detection. Sample to result takes about 1 hour.
