Conclusions This Thesis gives an overview of high-performance riquid chromatography in various separation modes for a characterization of selected proteins. various affinity stationary phases were prepared for analysis of pepsin, seminal plasma proteins and selected glycoproteins' choice of the affinity system suitable for a particular purpose is always a comprex probrem in which number of aspects must be considered. properties of the proteins to be separated and ligands used had to be taken into an account. The separation system should not influence the biorogicai activity ofproteins separated. From this point of view it is clear that for any each individuar system is necessary to find specific conditions for I) immobilizationof ligand, and II) separation conditions. Stationary phases with immob'ized 3,5-diiodo-L-tyrosine exhibited sufÍicient selectivity, proved to be useful for analysis ofporcine pepsin A and are appricable to practical sampres of human pepsin' Reversed-phase crs corumn is suitable for anarysis ofpepsin fragments obtained after a-chymotrypsin digestion. A study oť interaction of various forms of pepsin and pepsinogen are essentiar because of their high importance as crinicar diagnostic markers and as stomach enzyme.
