Purificación y caracterización bioquímica de un factor de difusión presente en el veneno de la serpiente Bothrops atrox (Jergon)

A protein of high molecular weight was purified from the venom of Bothrops atrox Peruvian snake, using DEAE Sephadex A-50 anion exchange chromatography and Sephadex G-50 gel molecular filtration, with 0,05M ammonium acetate, pH 5.0. It showed hyaluronidase activity, and was obtained until homogeneous state with a 145-fold, 72% of yield and a 0.5% of recovery of active protein. The enzyme showed a molecular weight of 110 kDa by SDS- PAGE under reducing and non reducing conditions. The stability assays indicated that hyaluronidase lost 60% of its activity after 150 hours at pH 5.0 and it was quickly inactivated
