preparation example Construction

[0164] Epitope-bearing peptides and polypeptides of the invention can be produced by any conventional method for preparing peptides or polypeptides, including recombinant methods using nucleic acid molecules of the invention. For example, short epitope-bearing amino acid sequences can be fused to larger polypeptides that can be used as vectors during recombinant production and purification, and to generate anti-peptide antibodies during immunization. Epitope-bearing peptides can also be synthesized using known chemical synthesis methods. For example, Houghten described a simple method for the synthesis of large numbers of peptides, as 10-20 mg of 248 different peptides representing single amino acid variants of a segment of the HA1 polypeptide were prepared and characterized (by ELISA-type binding studies) within 4 weeks. 13-residue peptides, Houghten, R.A (1985), A general method for rapid solid-phase synthesis of large numbers of peptides: specificity of antigen-antibody int...

Embodiment 1

[0757] Bacterial expression and purification of embodiment 1KGF-2

[0758] The DNA sequence ATCC #75977 encoding KGF-2 was first amplified with PCR oligonucleotide primers corresponding to the 5' and 3' sequences of the processed KGF-2 cDNA (including the signal peptide sequence). The 5' oligonucleotide primer contained the sequence 5'CCCCACATGTGGAAATGGATACTGACACATTGTGCC3' (SEQ ID NO. 3) containing an Afl III restriction enzyme site including and followed by KGF-2 starting from the putative start codon 30 nucleotides of the coding sequence. The 3' sequence 5'CCCAAGCTTCCACAAACGTTGCCTTCCTCTATGAG3' (SEQ ID NO. 4) contains the complement of the Hind III site followed by 26 nucleotides of KGF-2. These restriction enzyme sites are compatible with the restriction enzyme sites on the bacterial expression vector pQE-60 (Qiagen, Inc. Chatsworth, CA). pQE-60 encodes antibiotic resistance (AMpr), a bacterial origin of replication (ori), IPTG-regulated promoter oper...

Abstract

The present invention relates to various newly identified polynucleotides, polypeptides encoded by such polynucleotides, uses of such polynucleotides and polypeptides, and production of such polynucleotides and polypeptides. More specifically, the polypeptide of the present invention is keratinocyte growth factor, sometimes referred to hereinafter as "KGF-2," and formerly referred to as fibroblast growth factor 12 (FGF-12). The present invention also relates to the therapeutic use of KGF-2 for promoting or accelerating wound healing. The present invention also relates to new mutant forms of KGF-2 which show enhanced activity, increased stability, higher yield or better solubility.

Description

field of invention [0001] The present invention relates to newly identified polynucleotides, polypeptides encoded by such polynucleotides, uses of such polynucleotides and polypeptides, and production of such polynucleotides and polypeptides. More specifically, the polypeptide of the present invention is a keratinocyte growth factor, sometimes referred to hereinafter as "KGF-2," and formerly referred to as fibroblast growth factor 12 (FGF-12). The invention also relates to inhibiting the action of such polypeptides. The present invention also relates to the therapeutic use of KGF-2 to promote or accelerate wound healing. The present invention also relates to new mutant forms of KGF-2 which show enhanced activity, increased stability, higher yield or better solubility. Additionally, the present invention relates to methods of purifying KGF-2 polypeptides. Background of the invention [0002] The fibroblast growth factor family is a large family of gr...
