Product Introduction

Bioactivity

Bioactivity	Immobilized human ACE2 protein (Fc tag) at 2 μg/mL (100 μL/well) can bind Recombinant SARS-CoV-2 (BA.2.75)Spike RBD Protein (His&AVI Tag),Biotinylated, the EC50 is 1.8-6 ng/mL.
Description	SARS-CoV-2 BA.2.75 (Omicron) Spike RBD Protein (His & Avi), Biotinylated is expressed in HEK293 mammalian cells with His and Avi tag. The predicted molecular weight is 28.56 kDa and the accession number is YP_009724390.1.
Species	SARS-CoV-2
Expression System	HEK293 Cells
Tag	C-His-Avi
Accession Number	YP_009724390.1
Construction	A DNA sequence encoding the SARS-CoV-2 (BA.2.75) Spike RBD (YP_009724390.1, with mutation G339H, S371F, S373P, S375F, T376A, D405N, R408S, K417N, N440K, G446S, N460K, S477N, T478K, E484A, Q498R, N501Y, Y505H) (Arg319-Phe541) was expressed with a C-terminal polyhistidine tag followed by an AVI tag. The mutations were identified in the SARS-CoV-2 variant (known as variant BA.2.75). The expressed protein was biotinylated in vivo by the Biotin-Protein ligase (BirA enzyme) which is co-expressed. Predicted N terminal: Arg 319
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 solution filtered through a 0.22 μm filter, containing PBS, pH 7.4. 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.
