Fig. 2.

Individual insulin autoantibody (IAA) binding characteristics of one selected sample. Competition of binding to human [¹²⁵I]insulin by (a) protein extractions from food components [wheat flour, whole bovine milk and four representative infant formulas – regular non-hydrolyzed formula (REG), hypo-allergic hydrolyzed milk formula (HA), infant formula closely adapted to human breast milk (PRE), milk-free infant formula (SOM)] and (b) by milk protein fractions [alpha-casein, beta-casein, lactoglobulin and bovine serum albumin BSA)] are shown. IAA are expressed as bound radioactivity in counts per minute (cpm).
