SARS-CoV-2 Spike recombinant protein (RBD) (His-tagged, C-ter)
SARS-CoV-2 Spike recombinant protein (RBD) (His-tagged, C-ter) for SDS-PAGE,Binding Activity and Virus
|产品描述||HEK293 expressed, His-tagged (C-ter) SARS-CoV-2 Spike recombinant protein (RBD).|
|靶点名称||SARS-CoV-2 Spike protein (RBD)|
|A.A. 序列||Arg319 - Phe541 of SARS-CoV-2 Spike protein (YP_009724390.1) with 6X His tag at the C-terminus.|
|应用说明||Binding activity test: Measured by its binding ability in a functional ELISA. Immobilized Recombinant SARS-CoV-2 Spike RBD-His at 2µg/ml (100 µl/well) can bind Recombinant Human ACE2 with a linear range of 0.15-4.53 ng/ml.
Immobilized human ACE2 on COOH Chip, can bind SARS-COV-2 Spike RBD Protein with an affinity constant of 36.7 nM as determined in a SPR assay.
|纯化说明||0.22 µm filter sterilized. Endotoxin level is less than 0.1 EU/µg of the protein, as determined by the LAL test.|
|纯度||> 95% (by SDS-PAGE); > 95% (by HPLC)|
|缓冲液||PBS (pH 7.4)|
|重建||Reconstitute to a concentration of 0.1 - 0.5 mg/ml in sterile distilled water.|
|存放说明||Lyophilized protein should be stored at -20°C or -80°C. After reconstitution, aliquot and store at -20°C for up to one month, at 2-8°C for up to one week. Storage in frost free freezers is not recommended. Avoid repeated freeze/thaw cycles. Suggest spin the vial prior to opening.|
|注意事项||For laboratory research only, not for drug, diagnostic or other use.|
