The aim of the presented work is the study and biochemical characterization of some modified collagen materials (prepared on Institute of Material Science, Faculty of Chemistry, BUT), optimalization of collagen isolation from various types of animal tissues and testing of isolated collagen stability. First, isolation of collagen from five different animal tissues was performed with satisfactory yields. The concentration of total proteins was measured by Biuret and Hartree – Lowry method, the concentration of free amino groups was measured by TNBSA method. Protein analysis in colllagen preparatives was peformed by vertical electrophoresis PAGE-SDS and by microfluidic electrophoretic system Experion for comparison. Further purification and separation of collagen isolates by gel permeation chromatography was tested too. To detailed characterization thermal stability of collagen specimens was performed by high performance ultrasonic spectroscopy. Biological stability of collagen was tested in model physiological conditions.
