| Abstract: | Zn2+ inhibits the binding of 59Fe]lactoferrin to neutrophilic leucocytes. The inhibiting effect is proportional to zinc concentration in the range 10-330 mumol/l. Zn2+ inhibits the 59Fe]lactoferrin binding to the colostral cells in the same degree as PMN. The inhibiting effect of Zn2+ on 59Fe]lactoferrin binding to neutrophilic leucocytes is equal to those of non-labelled lactoferrin and transferrin. Fe2+ and Cu2+ does not have such effect on binding of 59Fe]lactoferrin to the PMN leucocytes. |
