Novel genes coding for mutant bovine and human aFGF are constructed. The unique genes are derived from genes encoding recombinant bovine and human aFGF by specific point mutations. Each gene construct is inserted into an expression vector which is used to transform an appropriate host. The transformed host cells produce unique mutant recobinant aFGF, human or bovine, which is purified and has enhanced or improved biological activity in the absence of heparin compared to the unmutated forms. |
