Application

Incorporation of asialofetuin (AF) in liposomes strongly enhance delivery to and endocytosis by cells displaying the AF receptor, notably hepatocytes. This provides a very efficient route for gene therapy.

Asialofetuin from fetal calf serum is suitable for use:in the assay of the lactose binding activity of the galectin-7 by immunodetection of in situ binding activity to asialofetuin immobilized on nitrocellulosein the inhibition of zona pellucida hardening of mouse oocytesas an acceptor in sialyltransferase enzyme activity assay

Biochem/physiol Actions

Feutins are glycoproteins that belong to the cystatin superfamily. They are characterized by the presence of two tandemly arranged cystatin-like domains and an unrelated domain. It binds to transforming growth factor (TGF)-β/BMP (bone morphogenic protein) cytokines.

Asialofetuin (AF) binds to asialoglycoprotein receptor (ASGP-R) and is employed as a ligand for drug delivery to the hepatocytes. It aids serum-resistant lipoplexes for efficient gene deliver into the HepG2 (human hepatoblastoma) cells.
