Recombinant MERS-CoV Spike S1 Protein (RP01303)

Publications (2) Datasheet

Overview

Product name Recombinant MERS-CoV Spike S1 Protein
Catalog No. RP01303
Description Recombinant MERS-CoV Spike S1 Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Tyr18-Glu725) of mers-cov Spike S1 (Accession #YP_009047204.1) fused with a mFc tag at the C-terminus.
Bio-Activity Measured by its binding ability in a functional ELISA. Immobilized Human CD26 (Catalog: RP01300LQ) at 2μg/mL (100μL/well) can bind MERS-CoV Spike S1 with a linear range of 0.5-420.21ng/mL.
Purity > 95% by SDS-PAGE.
Endotoxin < 0.1 EU/μg of the protein by LAL method.
Formulation Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.
Species MERS-CoV
The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity. The main functions for the Spike protein are summarized as: Mediate receptor binding and membrane fusion; Defines the range of the hosts and specificity of the virus; Main component to bind with the neutralizing antibody; Key target for vaccine design; Can be transmitted between different hosts through gene recombination or mutation of the receptor binding domain (RBD), leading to a higher mortality rate.
Synonym MERS-CoV Spike RBD
Expressed Host HEK293 cells

Swiss-Prot K9N5Q8
Gene ID 14254594
Storage Store the lyophilized protein at -20°C to -80°C for long term.
After reconstitution, the protein solution is stable at -20°C for 3 months, at 2-8°C for up to 1 week.
Reconstitution Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid votex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
