NR-53799?? Spike Glycoprotein S2 Extracellular Domain (ECD) from SARS-Related Coronavirus 2, Wuhan-Hu-1 with C-Terminal Histidine Tag, Recombinant from Baculovirus(Proteins)|SARS-Related Coronavirus 2|Spike Glycoprotein S2 Extracellular Domain (ECD) from SARS-Related Coronavirus 2, Wuhan-Hu-1 with C-Terminal Histidine Tag, Recombinant from Baculovirus|-20°C to -80°C|Sino BiologicalAcknowledgment for publications should read “The following reagent was obtained through BEI Resources, NIAID, NIH: Spike Glycoprotein S2 Extracellular Domain (ECD) from SARS-Related Coronavirus 2, Wuhan-Hu-1 with C-Terminal Histidine Tag, Recombinant from Baculovirus, NR-53799.”|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 S2 extracellular domain (ECD) from severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2), Wuhan-Hu-1 (GenPept: YP_009724390) was produced by transfection in insect cells using a baculovirus expression system and purified. NR-53799 lacks the signal sequence, contains 528 residues of the SARS-CoV-2 spike glycoprotein S2 ECD (amino acid residues S686 to P1213) and features a C-terminal poly-histidine tag. NR-53799 has a theoretical molecular weight of 59,370 daltons. Each vial contains approximately 50 ?g of purified recombinant protein in phosphate buffered saline (PBS, pH 7.0) supplemented with 2% glycerol. Note: NR-53799 was not lyophilized.
