 Source: HEK293 (Human Embryonic Kidney cell line)-derived.
 The KD (equilibrium binding constant) of Human FZD1 was measured at less than 10 nM with human Wnt3a as the ligand. The measurements were performed by the ForteBio Octet optical biosensor instrument.
 Purity > 95.0% as determined by SDS-PAGE.
