摘要:
The invention mainly relates to a method for manufacturing a polypeptide with the formula: (III) X 1 -X"-X 2 , in which X 1 and X 2 are each a peptide fragment, and X" is an amino-acid residue comprising a thiol function, said method including at least one step of reacting a ligation between a polypeptide with the formula: (I) X 1 -N(CH 2 CH 2 SH) 2 and a polypeptide with the formula: (II) H-X"-X 2 . The invention also relates to polypeptides with the formula (I) as well as to the method for obtaining same and to resin substrates suitable for obtaining same.
摘要:
The invention relates to a device for presenting peptides or proteins which can be used as a polypeptide chip for miniaturized detection of molecules which structurally or functionally complement said polypeptides. Said device consists of a flat support where polypeptides are covalently bound. The link between the polypeptides and the support results from the formation of a semicarbazone link. The semicarbazone link is a specific result of the reaction between polypeptides having an aldehyde or ketone function; and a support functionalized by semicarbazide groupings. The invention also relates to a method for preparing the supports and attaching the polypeptides to these supports in addition to the use of said devices thus obtained as polypeptide chips .
摘要:
The invention relates to the use of a mixture containing at least lipopeptides for vaccine production. Said lipopeptides comprise a peptide compound which has been bound in solution by means of a hydrazone linkage to at least one non-peptidic lipophilic carrier. The invention also relates to native sequences NS3 of the HCV.
摘要:
The invention relates to a method for assembling proteins from peptide fragments. Said method enables the production of proteins in a simple, reliable manner that can be applied on an industrial scale. This method makes it possible to produce proteins with therapeutic or diagnostic value. The invention also relates to kits used for implementing said method for synthesizing proteins and to kits used in testing and/or diagnosis.
摘要:
The invention concerns a functionalised solid support for the synthesis of compounds comprising at least an alpha -oxoaldehyde function, its method for preparation and its uses, in particular for preparing a bank of organic compounds, a diagnostic reagent, a microtitration plate and a biochip, such as a DNA chip. The invention also concerns a method for the synthesis of organic compounds comprising at least an alpha -oxoaldehyde function and alpha -oxoaldehyde peptides obtained by said method.
