Description
SARS-CoV-2 Spike NTD Protein (T19R, G142D, EF156-157del, R158G), His Tag (MALS verified) | S1D-C52Hh-100ug| Gentaur Distribution US, UK & Europe
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.
Source: SARS-CoV-2 Spike NTD, His Tag (S1D-C52Hh) is expressed from human 293 cells (HEK293). It contains AA Ser 13 - Leu 303 (Accession # QHD43416.1). The mutations (T19R, G142D, EF156-157del, R158G) were identified in the SARS-CoV-2 Delta variant (Pango lineage: B.1.617.2; GISAID clade: GK; Nextstrain clade: 21A/21I/21J).
