5 CONCLUSIONS This thesis surrrnrarizes the development of a multimethodological analýical approach employing microcolumn lectin affi1t1,9fuom1tography coupled to highir".otu,to; separation and dete9tion techniques, in order to facilitate the enrichmení of glyco-proteins aná giycopeptioes originating from small quantities of real samples. This is u"toauy a sipificant-ítep towara satis$'ing the demands of contemporary glycoproteomics, which rely orirurt *a small scale analyses, allowing the identification of low abundant protein components' The overď conclusions and contribution to the contemporaÍy scierrce are drawn in tbree followine chaoters. 5.1 combining Lectin Microcolumns with High-Resolution separation Techniques for Enrichment of Glycoproteins and Glycopeptides This section describes coupling small-scďe lectin aÍfinity chromatograpby on-line to high- resolution separation and detection techniques, with the utiliý of a microcolumn loaded with a lectin immobilized onto macroporous silica. Experimental results, involving optimization of coupling procedure, fabrication of lectin microcolumns, verification of tteir Uin&ng efficiency and their possibility of interfacing on-line with nano LC-MS/]víS, me summarizžd into thé following conclusions; o optimized coupling procedure involved resuspending only 125...
