  • Publication number: 20090093400
    Abstract: The present invention relates to a keratinocyte growth factor fragment, KGFdes1-23, or an analog thereof that is composed of a portion of an amino acid sequence of mature, full length keratinocyte growth factor, KGF163. The fragment exhibits at least a 2-fold increase in mitogenic activity as compared to a mature, recombinant keratinocyte growth factor, rKGF, but lacks a sequence comprising the first 23 amino acid residues; C-N-D-M-T-P-E-Q-M-A-T-N-V-N-C-S-S-P-E-R-H-T-R- (SEQ ID NO: 2) of the KGF163 N-terminus. The present invention also relates to a DNA molecule encoding KGFdes1-23, an expression vector and a transformed host containing the DNA molecule, and a method of producing KGFdes1-23 by culturing the transformed host. The present invention further relates to a conjugate of KGFdes1-23 and a toxin molecule, and the use thereof for treatment of hyperproliferative disease of the epidermis.

  • Patent number: 4716117
    Abstract: Hybridomas producing monoclonal antibodies specific for polypeptide fragments derived from human Factor VIIIC are provided. Class I hybridomas produce monoclonal antibodies reactive with a 80/77 kd doublet fragment or with both the 80/77 kd doublet and a 240 kd polypeptide. Class III hybridomas produce monoclonal antibodies reactive with the 240 kd polypeptide as well as a 92.5 kd fragment and its precursors. Class III antibodies show additional reactivity with a 40 kd thrombin digestion product. The monoclonal antibodies are useful for the separation of Factor VIIIC and its constituent polypeptides, as well as for the immunoassay of Factor VIIIC in biological samples.
