Abstract: Skin tests of the nondialysable fraction of lactose were
performed on patients with a clinical diagnosis of cow's milk
allergy. Yields of brownish-coloured residue allergens (ALG), were
0.006% from reagent grade lactose (ALG 1) and 0.011% from lactose
used in a commercial infant food formula (ALG 2). The ALG was
separated into 4 fractions by chromatography on Sephadex G-75.
Highest incidences of positive skin reaction among the 4 ALG 1 and
ALG 2 fractions were 8/9 and 8/12 resp. ALG fractions were identified
as a sugar protein complex and the protein moiety of ALG contained
high amounts of glutamic acid (or glutamine), threonine, asparagic
acid (or asparagine) and proline.
