Datasheets/ManualsPrintable datasheet for Recombinant SARS-CoV-2 Spike S1 Protein (OPAN06665)
Product Info
Tested Species Reactivity2019-nCoV
Predicted Species ReactivitySARS-CoV-2 / COVID-19 Virus, Severe acute respiratory syndrome coronavirus 2
Product FormatLyophilized PBS (pH 7.4)
::Endotoxin Level: < 0.1 EU/ug of the protein by LAL method.
Reconstitution and StorageReconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Store the lyophilized protein at -20°C to -80°C for long term. After reconstitution, the protein solution is stable at -20°C for 3 months, at 2-8°C for up to 1 week. Avoid repeated freeze/thaw cycles.
Purity>95% by SDS-PAGE, HPLC
Biological ActivityMeasured by its binding ability in a functional ELISA. Immobilized Recombinant SARS-CoV-2 Spike S1 at 2 ug/mL (100 uL/well) can bind recombinant Human ACE2 with a linear range of 0.15-6.85 ng/mL. Immobilized Human ACE2 on COOH Chip, can bind SARS-COV-2 Spike S1 with an affinity constant of 24.5 nM as determined in a SPR assay.

Description of TargetThe spike protein (S) of coronavirus (CoV) attaches the virus to its cellular receptor, angiotensin-converting enzyme 2 (ACE2). A defined receptor-binding domain (RBD) on S mediates this interaction.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity.
