摘要:
Unique genes coding for the amino acid sequence of bovine acidic fibroblast growth factor (aFGF) and human aFGF are constructed. The bovine gene is derived from reverse translation of the aFGF amino acid sequence while the human gene is derived by specific point mutations of the bovine gene. Each gene construct is inserted into an expression vector which is used to transform an appropriate host. The transformed host cells produce recombinant aFGF (r-aFGF), human or bovine, which is purified and has an activity equivalent to the native protein.

Recombinant DNA fragments are provided, and their nucleotide sequences determined which encode the antigenic determinants responsible for the immunogenicity and the immunological specificity of various proteins of Hepatitis A virus (hereinafter referred to as HAV), including the VP-1 protein, the main structural protein of HAV.

摘要:
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.

摘要:
A unique double cistron expression vector for the enhanced expression of recombinant human acidic fibroblast growth factor (r-haFGF) is disclosed. The double cistron expression vector results in about a 5 to 13-fold increase in the expression of r-haFGF.
