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.
Alternate Names: MERS-CoV Spike RBD
SWISS: K9N5Q8
GeneID: 14254594
Species: MERS-CoV
Purity: ≥ 95 % as determined by SDS-PAGE.
Storage: Store at -20℃. Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.
Background: 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.
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.
