Antibody Specifications

ELISA (recommended work dilution = 1:80,000)
Host Species:
This antibody was produced from antiserum of rabbits immunized with a recombinant SARS-CoV-2 S2 Subunit. The IgG fraction was purified by Protein A affinity chromatography.
Product is supplied as a powder obtained from lyophilization of purified antibody in 1X PBS, aliquot using ddH2O. Reconstitute the antibody with sterile water to a final concentration of 1 mg/ml.
Species Reactivity:


It's been reported that 2019-nCoV can infect the human respiratory epithelial cells through interaction with the human ACE2 receptor.The spike protein is a large type I transmembrane protein containing two subunits, S1 and S2. S2 contains basic elements needed for the membrane fusion.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity.


This antibody was selected for its ability to bind to the virus SARS-CoV-2 Spike Protein Subunit 2 (S2) from the disease COVID-19.


Store at 4°C if intended for use within one month, otherwise, store at -20°C to -80°C. The lyophilized antibody is stable for at least 18 months after the date of receipt when stored at -20°C to -80°C. After reconstitution, it can be aliquoted and stored frozen at -20°C to -80°C in a manual defrost freezer for at least 6 months without detectable loss of activity. Upon reconstitution, the antibody can also be stored for 1 month at 4°C. Please avoid freeze-thaw cycles, as this will lower the activity of the antibody.
12 months from the date of shipment when stored properly.
