产品说明

一般描述

Recombinant 2019-nCoV Spike RBD-His Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Arg319-Phe541) of 2019-ncov Spike RBD-His (Accession #YP_009724390.1) fused with a 6XHis tag at the C-terminus.

生化/生理作用

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.

重悬

For lyophilized protein : Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water.

储存及稳定性

Store the lyophilized protein at -20℃ to -80℃ for long term. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8 ℃ for up to 1 week. This product is stable at ≤ -70℃ for up to 6 months from the date of receipt. For optimal storage, aliquot into smaller quantities after centrifugation and store at recommended temperature.
