NR-53798?? Spike Glycoprotein S1 Domain from SARS-Related Coronavirus 2, Wuhan-Hu-1 with C-Terminal Histidine Tag, Recombinant from HEK293 Cells(Proteins)|SARS-Related Coronavirus 2|Spike Glycoprotein S1 Domain from SARS-Related Coronavirus 2, Wuhan-Hu-1 with C-Terminal Histidine Tag, Recombinant from HEK293 Cells|-20°C to -80°C|Sino BiologicalAcknowledgment for publications should read “The following reagent was obtained through BEI Resources, NIAID, NIH: Spike Glycoprotein S1 Domain from SARS-Related Coronavirus 2, Wuhan-Hu-1 with C-Terminal Histidine Tag, Recombinant from HEK293 Cells, NR-53798.”|Quantity limit per order for this item is 1. This item can be ordered twice a year. Orders over this limit will be sent to NIAID for approval before shipment.
A recombinant form of the spike glycoprotein S1 domain from severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2), Wuhan-Hu-1 (GenPept: YP_009724390) was produced by transfection in human embryonic kidney HEK293 cells and purified. NR-53798 lacks the signal sequence, contains 670 residues of the SARS-CoV-2 spike glycoprotein (amino acid residues V16 to R685) and features a C-terminal poly-histidine tag. NR-53798 has a theoretical molecular weight of 76,500 daltons.
The biological activity of NR-53798 was measured by its binding ability in a functional ELISA, in which immobilized human ACE2 protein (Fc tag) (Sino Biological 10108-H05H) at 2 ?g/mL (100 ?L/well) can bind NR-53798; the half maximal effective concentration (EC50) of NR-53798 is 200 to 600 ng/mL. The biological activity of NR-53798 was also measured by its binding ability using biosensor analysis, in which human ACE2 protein (Fc tag) (Sino Biological 10108-H05H) can bind NR-53798; the affinity constant is 47.7 nM.
Each vial contains approximately 50 ?g of purified recombinant protein in phosphate buffered saline (PBS, pH 7.4). Note: NR-53798 was not lyophilized.
