Internalization of human lactoferrin by the Jurkat human lymphoblastic T-cell line.

Abstract

Binding of either iron-saturated or iron-free lactoferrin to the Jurkat human lymphoblastic T-cell line was saturable with a dissociation constant Kd of 40 nM. The total number of binding sites was estimated to be approximately 300,000. Non-specific binding did not exceed 30% of the total binding. Removal of the 4 clustered arginine residues of lactoferrin… (More)
