Storage/StabilityStore at -20℃ for 12 months to avoid repeated freeze-thaw.introduction:Coronavirus is a class of viruses with membranous capsule, whose genome is linear single-stranded RNA virus, which is divided into α, β, γ, δ four genera. The novel coronavirus belongs to the genus coronavirus. Coronavirus contains at least four structures: Spike Protein, Envelope Protein, Membrane Protein and N Nucleocapsid Protein.The S protein is located on the envelope surface of the virus and can bind to the host cell surface receptor Ace2.The spatial structure of S protein can be divided into two parts, S1 and S2 parts. S1 contains the receptor binding region (RBD).This product is a humanized monoclonal antibody specific for the identification of novel coronavirus acanthosis protein, expressed in 293 cell system.Antibody activity was verified by ELISA with recombinant S-ECD and S-RBD proteins, which were suitable for detection of novel coronavirus.
