Preparation of Plasminogen by Affinity Chromatography
Background: Plasminogen is one of the compounds derived from human plasma. Activation of plasminogen produces plasmin. Plasmin is able to lyse fibrinogen, fibrin, and some other human plasma proteins. The aim of the present work was to study the separation of human plasminogen by affinity chromatography using gel lysine Sepharose. Materials and Methods: Normal human plasma was used as the...
متن کاملFrontal affinity chromatography: A unique research tool for biospecific interaction that promotes glycobiology
Combination of bioaffinity and chromatography gave birth to affinity chromatography. A further combination with frontal analysis resulted in creation of frontal affinity chromatography (FAC). This new versatile research tool enabled detailed analysis of weak interactions that play essential roles in living systems, especially those between complex saccharides and saccharide-binding proteins. FA...
متن کاملBiospecific Elution from Non-Specific Adsorbents (‘Affinity Elution’)
Enzymes adsorbed to ion exchangers are in many cases specifically desorbed by interaction with their ligands. This phenomenon has been variously called ‘specific elution with substrate’ or ‘affinity elution’ in the literature (von der Haar, 1974). Because the most effective ligands for elution are those containing charged groups identical with those on the ion exchanger (positive groups in the ...
متن کاملBiospecific-elution chromatography with 'imphilytes' as stationary phases.
Six out of seven enzymes tested (four of them nicotinamide nucleotide-dependent dehydrogenases) showed differences in chromatographic behaviour in the presence and absence of their biospecific ligands, when chromatographed on immobilized amphipathic ampholytes ('imphilytes') as stationary phases. Some enzymes were adsorbed more tightly, others less tightly, in the presence of ligands. These res...
متن کاملSome properties of a detergent-solubilized NADPH-cytochrome c(cytochrome P-450) reductase purified by biospecific affinity chromatography.
NADPH-cytochrome c (cytochrome P-450) reductase (EC 1.6.2.4) has been purified to homogeneity, as judged by sodium dodecyl sulfate disc gel electrophoresis, from detergent-solubilized rat and pig liver microsomes using an affinity chromatography procedure. Treatment of microsomes with a polyethoxynonylphenyl ether plus either cholate or deoxycholate and subsequent batch-wise DEAE-cellulose chro...
