A reliable and selective liquid chromatography-ultraviolet detection method for determination of tylosin has been developed. The extraction of analyte from feedingstuffs was performed with solution of citric buffer and methanol. The extracts were cleaned up by solid phase extraction procedure using a octadecyl cartridge. Samples were brought up to dryness and dissolved in phosphate buffer. The analysis...
Proteins were extracted from F. hepatica collected on cattle and sheep. The extract was purified in the column with sephadex G-25. The proteins were separated using the Davis method in electrophoretic systems constructed by the authors, in the columns and in blocks in polyacrylamid gel. The electrophoregrams served for making densometric diagrams and for calculating electrophoretic mobility coefficient...
