应用说明

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.

属性

形式 Powder
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.
