[L-fucose-specific lectin from pike perch (Lucioperca lucioperca L.) roe. Purification and studies of carbohydrate specificity].

L-fucose-specific lectin was purified from pike perch (Lucioperca lucioperca L.) roe by affinity chromatography on ovariomucine H-sepharose from a human ovary cyst. Three bands were detected after disk-electrophoresis in PAAG in alkaline (pH 8.9) and five bands--in acidic system (pH 4.3). According to electrophoresis data in 15% SDS-PAGE the lectin contains two components with molecular weight 13-14 kDa. Molecular weight of the lectin is 50 kDa according to gel-chromatography on tojopearl HW-55. The immunochemical properties of the lectins from perch (Persa fluviatilis L.) roe and pike perch (Lucioperca lucioperca L.) roe are similar.
