Source	DNA sequence encoding extracellular fragment[16-683] of COV2 Spike S1 [accession# QIC53204.1] variant (B.1.1.529/Omicron) (A67V, del69-70, T95I, del142-144, Y145D, del211, L212I, ins214EPE, G339D, S371L, S373P, S375F, K417N, N440K, G446S, S477N, T478K, E484A, Q493R, G496S, Q498R, N501Y, Y505H, T547K, D614G, H655Y, N679K, P681H)including a C terminal polyHis tag was expressed in HEK cells.
Molecular weight	Recombinant COV2 spike S1 subunit B.1.1.529 encodes the COV2 spike glycoprotein S1 sequence . This molecule has a calculated mass of approximately 76kDa. Recombinant S1 migrates due to glycosylation as an approximately 120 kDa protein under reducing conditions in SDS-PAGE.
Activity	The activity was tested by binding Human ACE2 in functional ELISA assay.
Endotoxin	Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).
Presentation	Recombinant COVID-19 Spike S1 was lyophilized from 0.2 µm filtered PBS solution pH7.4
Reconstitution	A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
Storage	The lyophilized protein is stable for at least 2 years from date of receipt at -20° C.
Usage	This product is for research purposes only.It may not be used for therapeutics or diagnostic purposes..
