[The pathogenetic importance of peanut lectin binding sites in infectious, toxic and neoplastic processes].

Labelled lectins are generally used for identification of mono-, oligo- and polysaccharides in histochemistry. The aim of this work is to demonstrate in addition the importance of the labelled (FITC and peroxidase) lectin from peanut (peanut agglutinin = PNA) with regard to the pathogenesis of some infectious and neoplastic diseases. Thereby, PNA-binding sites have been shown as differentiation marker in embryonic kidneys and in dysontogenetic.
