Submit ReviewSBP1-FITC is a fluorescently labelled peptide derived from human ACE2 (SBP1, Cat. No. 7233). Composed of SBP1 conjugated to FITC (Fluorescein-5-isothiocyanate; Cat. No. 5440). SBP1 binds receptor binding domain (RBD) of insect-derived SARS-CoV-2 spike protein (KD = 1.3 μM for N-terminal biotinylated, insect-derived spike protein RBD; see Zhang et al preprint publication).
Please note - unpublished, in-house data suggests SBP1 has approximately 75-fold lower affinity for insect-derived SARS-CoV-2 RBD than reported by Zhang et al.
