SARS-CoV-2 nsp8 Antibody [CoraFluor™ 1] Summary

• Description: CoraFluor(TM) 1 is a high performance terbium-based TR-FRET (Time-Resolved Fluorescence Resonance Energy Transfer) or TRF (Time-Resolved Fluorescence) donor for high throughput assay development. CoraFluor(IM) 1 absorbs UV light at approximately 340 nm, and emits at approximately 490 nm, 545 nm, 585 nm and 620 nm. It is compatible with common acceptor dyes that absorb at the emission wavelengths of CoraFluor(TM) 1. CoraFluor(TM) 1 can be used for the development of robust and scalable TR-FRET binding assays such as target engagement, ternary complex, protein-protein interaction and protein quantification assays.

Background

SARS-CoV-2 Nonstructural Protein 8 (NSP8) is one of the sixteen nonstructural proteins of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the causative agent of COVID-19 (1). SARS-CoV-2 NSP8 is 198 amino acids (aa) with a theoretical molecular weight of 21.9 kDa (1,2). The amino acid sequence alignment of SARS-CoV and SARS-CoV-2's NSP8 has 97.5% sequence identity and 100% sequence similarity (1). SARS-CoV-2 NSP8 heterodimerizes with NSP7, which forms a complex with NSP12 (1-4). NSP8 alone in its monomeric form can also complex with NSP12, generating the RNA polymerase complex (1,4). Additionally, NSP8 is shown to interact with the SARS-CoV-2 open reading frame 6 (ORF6), encouraging RNA polymerase activity (1).
