NR-55415?? Spike Glycoprotein S1 Domain from SARS-Related Coronavirus 2, Y144del Variant with C-Terminal Histidine Tag, Recombinant from HEK293 Cells(Proteins)|SARS-Related Coronavirus 2|Spike Glycoprotein S1 Domain from SARS-Related Coronavirus 2, Y144del Variant with C-Terminal Histidine Tag, Recombinant from HEK293 Cells|-20°C or colder|ACROBiosystemsAcknowledgment for publications should read “The following reagent was obtained through BEI Resources, NIAID, NIH: Spike Glycoprotein S1 Domain from SARS-Related Coronavirus 2, Y144del Variant with C-Terminal Histidine Tag, Recombinant from HEK293 Cells, NR-55415.”|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 (S) glycoprotein S1 domain from severe acute respiratory syndrome related coronavirus 2 (SARS-CoV-2), Y144del variant was produced by transient transfection in human embryonic kidney HEK293 cells and purified by affinity chromatography. NR 55415 lacks the signal sequence, contains 669 residues of the SARS-CoV-2 S glycoprotein (amino acid residues V16 to R685) and features a C-terminal poly-histidine tag. NR-55415 is a variant of SARS-CoV-2 which contains the Y144del mutation in the S glycoprotein as compared to the SARS-CoV-2 reference sequence (GenPept: QHD43416). NR-55415 has a theoretical molecular weight of approximately 76,700 daltons. The crystal structure for the wild-type S glycoprotein from SARS-CoV-2 has been solved at 2.8 ? resolution (PDB: 6VXX).
The S glycoprotein mediates viral binding to the host angiotensin converting enzyme 2 (ACE2). This protein forms a trimer, and when bound to a host receptor allows fusion of the viral and cellular membranes. New SARS-CoV-2 mutations in the S glycoprotein are currently under study, and a United Kingdom variant (also known as 20B/501Y.V1 or B.1.1.7 lineage) includes the Y144del mutation.
The biological activity of NR-55415 was measured by its binding ability in a functional ELISA, in which immobilized NR-55415 at 2 ?g/mL (100 ?L/well) can bind human ACE2 protein (Fc tag) (ACROBiosystems AC2-H5257); the linear range is 0.1 to 3 ng/mL.
Each vial contains approximately 100 ?g of purified recombinant protein lyophilized in phosphate-buffered saline, pH 7.4 and 10% trehalose.
