An Autoradiographic Study on the Uptake of S35-Labelled Sodium Sulphate in the Mast Cells

Abstract
Stripping film autoradiography was used to demonstrate S35 in mast cells of young rats previously injd. subcut. with 27 [mu]c/g. body wt. of S35 labelled Na2SO4. Uptake of S35 was max. at 48 hrs., decreasing only slightly thereafter up to 18 days.
