Product Introduction

Bioactivity

Bioactivity	Immobilized Recombinant Human ACE2 / Angiotensin-Converting Enzyme 2 Protein (Fc Tag) at 2μg/mL (100μL/well) can bind Recombinant SARS-CoV-2 XBB.1.16(Omicron)Spike S1+S2 trimer Protein(ECD,His Tag) , the EC50 is 5-15 ng/mL.
Description	SARS-CoV-2 XBB.1.16 (Omicron) Spike S1+S2 trimer Protein (His) is expressed in HEK293 mammalian cells with His tag. The predicted molecular weight is 136.87 kDa and the accession number is YP_009724390.1.
Species	SARS-CoV-2
Expression System	HEK293 Cells
Tag	C-His
Accession Number	YP_009724390.1
Construction	A DNA sequence encoding the SARS-CoV-2 (XBB.1.16) Spike S1+S2 (YP_009724390.1, with mutations T19I, V83A, G142D, H146Q, E180V, Q183E, G339H, R346T, L368I, S371F, S373P, S375F, T376A, D405N, K417N, N440K, V445P, G446S, N460K, S477N, T478R, F490S, Q498R, N501Y, Y505H, D614G, H655Y, N679K, P681H, N764K, D796Y, F817P, A892P, A899P, Q954H, A942P, N969K, K986P, V987P and furin cleavage site mutants) expressed with the bacteriophage T4 fibritin and a polyhistidine tag at the C-terminus. The mutations were identified in the SARS-CoV-2 variant (known as variant XBB.1.16). Predicted N terminal: Val16
Protein Purity	≥ 90 % as determined by SDS-PAGE. ≥ 90 % as determined by SEC-HPLC.
Endotoxin	< 1.0 EU/μg of the protein as determined by the LAL method.
Formulation	Lyophilized from a sodium citrate buffer system at pH 6. 0.Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization.
Reconstitution	A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information.
Stability & Storage	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
Shipping	In general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice.
