Abstract

Aim of this work is to propose an analytical protocol for proteinaceous binder identification in paintings using tryptic peptide analysis and MALDI-TOF mass spectrometry strengthened with MALDI-TOF/TOF tandem mass spectrometry (LIFT method). Proteinaceous binders are enzymatically digested with trypsin. From each individual protein frequently occurring in binders, a specific set of peptides is releasing during enzymatic digestion giving a peptide mass fingerprint (PMF) of that particular protein. The most intensive peptide peaks in PMF were determined and annotated with their corresponding amino acid sequence by MALDI-TOF/TOF analysis and subsequent database search. Before analyzing historical painting samples, procedure was tested and optimized on several painting model samples for a reliable and efficient identification of proteinaceous materials. The method is avoiding sample manipulation as much as possible in order to reduce sample loss. Since the applied procedures led to protein identification of binding media in model samples, MALDI-TOF/TOF was for the first time applied for analysis of proteinaceous binders in old painting samples.

Abstract

The effect of the composition of mixed tris-beta-diketonato metal complexes on their hR(F) Values obtained by a thin layer of polyacrylonitrile sorbent was examined with two series of complexes of the type [M(acac)(3-n)(phacphac)(n)] and [M(acac)(3-n)(phacphSac)(n)], where M is Co(III), Cr(III) or Ru(III), acac = 2,4-pentanedionato ion, phacphac = 1,3-diphenyl-1,3-propanedionato ion and phacphSac = 3-mercapto-1,3-diphenyl-prop-2-en-1-on ion (n = 0-3). Ten mobile phases were used for their chromatographic separation. In all instances hR(F) values of the examined complexes decrease when the oxygen atom in beta-diketonato ligand is substituted by a less electronegative sulphur atom. It has also been established that the substitution of acac ligand results in a hR(F) value decrease. In all the examined cases a linear dependence between the R-M values of the complexes and the number of acac ligands substituted by phacphSac ligands was established. The separation mechanisms and the separation factors are discussed. (C) 1999 Elsevier Science B.V. AU rights reserved.
