Isolation and Purification of Thrombolytic Enzyme Extracted from Earthworm Punjab, Pakistan
The Cardiovascular disease due to thrombus (clot) formation is the major factor of death throughout the world. Earthworms being the eco engineers has thrombolytic enzyme that can be used for thrombolysis. The thrombolytic enzyme was isolated and purified from supernatant of earthworm Apporectodea longa by column chromatography. Six Strain BKT 11, BKT 15, BKT 17, BKT 26, BKT 27 and BKT 28 shows the thrombolytic activity 791.64 U/mg, 1362.39 U/mg, 1205.4 U/mg, 710.63 U/mg, 529.66 U/mg and 625.00 U/mg respectively. Thrombolytic activity was confirmed by blood clot lysis method. Different concentrations 50 μl,100 μl, 150 μl, 200 μl and 250 μl of extracted enzyme were applied on 25mg of wet blood clot along with control where distill water used. These fractions of extracted enzymes represent the dissolution of clot (thrombolysis). The molecular weight 32 KDa was determined by sodium dodecyl sulphate gel electrophoresis (SDS-PAGE). Results show that extracted elute have potential of fibrinolytic activity in this specie of earthworm and it can serve as a suitable therapeutic agent.
