Product information "SARS-CoV-2 Spike S1 Protein (RBD) - without Tag"

SARS-CoV-2 Spike Protein RBD Recombinant without His-tag is a recombinant protein that is in liquid form buffered in PBS. This protein was produced recombinantly and is HIS-tagged at the C-terminus.

This receptor binding domain (RBD) of the SARS-CoV-2 spike protein is a 223 amino acid glycoprotein corresponding to positions 319-541 of the S1 sequence of the spike protein. Cells expressing ACE2 (angiotensin converting enzyme 2) are infected by SARS-CoV-2. ACE2 binds as a cellular receptor to the viral spike protein (S) after proteolytic cleavage. The receptor-binding domain (RBD) of the S protein is the domain that specifically binds to ACE2. The S1-RBD protein plays a key role in the induction of neutralising antibody and T-cell responses and the establishment of protective immunity. RGD stands for the amino acid sequence: Arg-Gly-Asp (RGD) in position 403-405 of the spike protein. These 3 amino acids are conserved across all known SARS Co-2 sequences, but not in other coronaviruses.

SARS-CoV-2 (2019-nCoV) Spike S1 Protein can be used for the development of diagnostic kits. It is not for direct detection of SARS-Cov-2. The counterpart to SARS-CoV-2 is ACE2 (angiotensin converting enzyme-2), which has previously been described as a receptor for SARS-CoV.
