Extracellular human superoxide dismutase, dna fragment encoding it, recombinant method for making it and vectors and cells for use in the method, method for recovering the dismutase and pharmaceutical compositions comprising it
A superoxide dismutase originally found in extracellular body fluids and therefore termed extracellular superoxide dismutase (EC-SOD) is prepared by growing a cell line, preferably of mammalian origin, producing EC-SOD and recovering the EC-SOD secreted from the cells or by inserting a DNA sequence encoding EC-SOD into a suitable vector, introducing the recombinant vector into a host cell, growing the cell and recovering the EC-SOD produced. EC-SOD may be used for the prophylaxis or treatment of diseases or disorders associated with the presence or formation of superoxide radicals.
