Biotin SBP1 - Biotin Labeled

Fragment of the angiotensin-converting enzyme 2 (ACE2) peptidase domain (PD) alpha1 helix, a domain important for the interaction of ACE2 with the severe acute respiratory syndrome (SARS coronavirus receptor binding domain (SARS-CoV-2-RBD). SBP1 associates with the SARS-CoV-2-RBD with nanomolar affinity and can potentially block the key mechanism by which SARS CoV-2 initiates entry into human cells. This peptide has a covalently bonded N-terminal Biotin tag that can be used for detection and purification and contains a polyethylene glycol spacer (PEG4).
