the in vitro binding of 67ga to tumor cells ( burkitt 's lymphoma ) was apparently promoted by the addition of transferrin or lactoferrin to the incubation medium , but this glycoprotein enhancement of gallium uptake by the cells was dependent on the albumin level , decreasing in absolute uptake as the albumin concentration was increased , suggesting nonspecific binding of glycoproteins to cells .
