Latest Patents

Zimmerman holds a patent for a large-scale method for the purification of high purity heparinase. This invention presents an improved process for extracting active heparinase and heparinase-like enzymes from Gram-negative organisms, specifically Flavobacterium heparinum. The primary advantage of this process is its ability to facilitate large-scale processing and achieve high yields of heparinase. The method involves releasing heparinase from the periplasmic space of the organism through osmotic shock treatment, followed by fractionation using cation exchange chromatography and optional electrophoresis or gel filtration chromatography. Two proteins with heparinase activity have been isolated, with molecular weights of approximately 42,000 Daltons and between 65,000 to 75,000 Daltons.
