Catalog No. ABIN7013276

Product Details

Target: SARS-CoV Spike (SARS-CoV S) (SARS-Coronavirus Spike Protein (SARS-CoV S))

Protein Type: Recombinant

Biological Activity: Active

Protein Characteristics: AA 14-1195

Origin: SARS Coronavirus (SARS-CoV)

Source: HEK-293 Cells

Purification tag / Conjugate: This SARS-CoV Spike protein is labelled with His tag.

Sequence: AA 14-1195

Characteristics: SARS S protein (R667A, K968P, V969P), His Tag is expressed from human 293 cells (HEK293). It contains AA Ser 14 - Pro 1195 (Accession # AAP13567.1(R667A, K968P, V969P). The recombinant protein is expressed with T4 fibritin trimerization motif and a polyhistidine tag at the C-terminus. Proline substitutions (K968P, V969P) and alanine substitutions (R667A) are introduced to stabilize the trimeric prefusion state of SARS-CoV S protein and abolish the furin cleavage site, respectively.

Background: It's been reported that Coronavirus can infect the human respiratory epithelial cells through interaction with the human ACE2 receptor. 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.
