Recombinant Human IGFBP4 protein (NP_001543.2) is produced in Fuco-Adjusted Human Cell Line. This expression system is used for the production of glycoproteins and antibodies with different fucosylation degrees.
This gene is a member of the insulin-like growth factor binding protein (IGFBP) family and encodes a protein with an IGFBP domain and a thyroglobulin type-I domain. The protein binds both insulin-like growth factors (IGFs) I and II and circulates in the plasma in both glycosylated and non-glycosylated forms.
