Lactoferrin, a granule-associated glycoprotein, is a cationic protein with a high proportion of arginine and lysine at the N-terminal region, with two glycosylation and several iron-binding sites. Lactoferrin is highly antibacterial against both gram-positive and gram-negative bacteria at concentrations ranging from 3 to 50 μg/ml. It is believed that these lethal effects are due to a direct interaction of lactoferrin with the cell surface and subsequent disruption of normal permeability functions of the membrane, a so-called dissipation of proton motive force action . Similarly, expression of an antimicrobial tachyplesin gene from Asian horseshoe crabs led to antibacterial activity against Erwinia spp. in transgenic potato .

usage and dosage

Lactoferrin was used in the fractionation of lactoperoxidase and lactoferrin from bovine whey using a cation exchange membrane. It was used in the determination of lactoferrin and immunoglobulin G in animal milks by new immunosensors.
