  • Patent number: 7414106
    Abstract: Disclosed herein is a new method for the solid phase peptide synthesis (SPPS) of C-terminal peptide ? thioesters using Fmoc/t-Bu chemistry. This method is based on the use of an aryl hydrazine linker, which is totally stable to conditions required for Fmoc-SPPS. When the peptide synthesis has been completed, activation of the linker is achieved by mild oxidation. The oxidation step converts the acyl-hydrazine group into a highly reactive acyl-diazene intermediate which reacts with an ?-amino acid alkylthioester (H-AA-SR) to yield the corresponding peptide ?-thioester in good yield. A variety of peptide thioesters, cyclic peptides and a fully functional Src homology 3 (SH3) protein domain have been successfully prepared.

    Abstract: It is an object of the present invention to provide novel binding molecules for factor VIII and factor VIII-like proteins. Preferred binding molecules of the present invention exhibit not only distinct characteristics for binding of the target factor VIII polypeptides but also specific and desirable characteristics for release (elution) of the target polypeptides. Especially preferred binding molecules according to the invention are short polypeptide sequences, characterized by a stable loop structure.

  • Patent number: 7109040
    Abstract: The present invention provides methods for analyzing a peptide or peptides of interest in a protein sample using a combination of a relatively generic isotope tag with a decoupled selection process, allowing simplified customization of the application with a single reagent. These methods comprise providing a first and a second protein sample; labeling the first protein sample with a first Universal Peptide Isotope Tag (U-PIT) reagent and the second protein sample with a second U-PIT reagent; separating the peptide of interest from the combined first and second protein samples; and determining the relative amount of the first U-PIT reagent and the second U-PIT reagent bound to the peptide or peptides of interest. The U-PIT label of the present inventive methods has the following general formula A-B-C wherein A is a nucleophilic reactive group, B is a detectable moiety that can be isotopically labeled, and C is a charge replacement group.

  • Patent number: 7094548
    Abstract: The present invention provides novel identification polypeptides containing multiple copies of an antigenic domain joined in tandem to provide increased sensitivity for the detection and purification of target peptides, a cleavable linking sequence and optionally a spacer domain. Further provided are hybrid polypeptide molecules composed of an identification polypeptide and a target peptide which are produced by recombinant DNA technology and purified using affinity chromatography using one or more ligands. Accordingly, also provided are DNA expression vectors containing DNA encoding for identification polypeptides and methods for using such identification polypeptides for the purification of target peptides. Also provided are methods of constructing DNA vectors encoding the novel identification polypeptides and DNA expression vectors encoding the identification polypeptides linked to a target peptide.

  • Patent number: 7094580
    Abstract: A method of perlecan isolation (from the EHS tumor) which produces “clean” (i.e. substantially “pure”) perlecan is disclosed. Clean perlecan is thus produced in sufficient quantities for use in a number of different in vitro and in vivo assays. In addition, this isolation method exploits a newly discovered aggregating property of a ˜220 kDa heparan sulfate proteoglycan (HSPG) observed during gel filtration chromatography, which allows it to be effectively separated from non-aggregating perlecan. The method employs specific cation exchange, anion exchange, molecular sieve chromatography and immobilized GAG affinity chromatography. It is demonstrated that there are no other contaminating proteins in the perlecan and HSPG preparations, and that the perlecan core protein is intact. Improved, clean perlecan based, rodent models of fibrillar amyloid protein deposition, accumulation and/or persistence in tissues are disclosed.

  • Patent number: 7087231
    Abstract: The present invention relates to an in vitro diagnostic method for malaria in an individual comprising placing a tissue or a biological fluid taken from an individual in contact with a molecule or polypeptide composition, wherein said molecule or polypeptide composition comprises one or more peptide sequences bearing all or part of one or more T epitopes of the proteins resulting from the infectious activity of P. falciparum, under conditions allowing an in vitro immunological reaction to occur between said composition and the antibodies that may be present in the tissue or biological fluid, and in vitro detection of the antigen-antibody complexes formed. The invention further relates to a polypeptide comprising at least one T epitope from a liver-stage specific protein produced by P. falciparum and a vaccine composition directed against malaria comprising a molecule having one or more peptide sequences bearing all or part of one or more T epitopes resulting from the infectious activity of P.
