title: Prony-Householder method applied to 31P NMR signals: II. Study of conjugates of ara-AMP with lactosaminated albumin.
abstract: Conjugates of 9-beta-D-arabinofuranosyladenine 5'-monophosphate (ara-AMP) with lactosaminated albumin (L-SA), obtained by using two different coupling procedures, produce antibodies in rats and mice which display only a small cross-reactivity. 31P NMR signals from the two conjugates have been examined to clarify whether different lysine and histidine residues are involved in the two reaction pathways. The occurrence of different chemical shifts and linewidths between the two conjugates, as evidenced by processing the signals with the Prony-Householder method, indicates the formation of two different complexes.
