SARS-CoV BtKY72 Spike Trimer, His Tag (SPN-S52Hu) is expressed from human 293 cells (HEK293) with T4 fibritin trimerization motif and a polyhistidine tag at the C-terminus. It contains AA Thr 13 - Pro 1198 (Accession # A0A3Q8AKM0 (K669A, KV971-972PP) ) .

Product Specifications

Background

The spike protein is a large type I transmembrane protein containing two subunits, S1 and S2. S1 mainly contains a receptor binding domain (RBD), which is responsible for recognizing the cell surface receptor. S2 contains basic elements needed for the membrane fusion.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity.

Specifications

This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 136.7 kDa. The protein migrates as 160-190 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
