A specific protein exhibiting immunological cross-reactivity with chicken riboflavin carrier protein has been purified to homogeneity from human amniotic fluid by use of ion-exchange and affinity chromatography. The protein is similar to its avian counterpart in terms of molecular size, distribution of 125I-labelled tryptic peptides during finger printing, and preferential binding to riboflavin. Immunologically, they are homologous since most of the monoclonal antibodies raised against the avian protein cross-react with the purified human vitamin carrier.
