Purification of polysaccharide protein conjugates
The invention describes a method of purifying polysaccharide protein conjugates using mixed mode chromatography. The method involves contacting a crude polysaccharide protein conjugate with a mixed mode resin comprising an inert porous shell and an activated core under conditions of low conductivity that allow binding of the contaminants and collecting the unbound polysaccharide protein conjugate in a flowthrough.
Fusion proteins comprising a non-cytotoxic protease, a translocation domain, and a targeting moiety that binds a galanin receptor and methods for treating, preventing or ameliorating pain using such fusion proteins
Single chain polypeptide fusion protein, comprising: a non-cytotoxic protease capable of cleaving a protein of the exocytic fusion apparatus of a nociceptive sensory afferent; a galanin targeting moiety; a protease cleavage site; a translocation domain; a first spacer located between the non-cytotoxic protease and the protease cleavage site; and a second spacer located between the galanin targeting moiety and the translocation domain.
FUSION PROTEINS AND METHODS FOR TREATING, PREVENTING OR AMELIORATING PAIN
A single chain polypeptide fusion protein, comprising: a non-cytotoxic protease capable of cleaving a protein of the exocytic fusion apparatus of a nociceptive sensory afferent; a galanin targeting moiety; a protease cleavage site at which site the fusion protein is cleavable by a protease; a translocation domain capable of translocating the protease from within an endosome, across the endosomal membrane and into the cytosol of the nociceptive sensory afferent; a first spacer located between the non-cytotoxic protease and the protease cleavage site; and a second spacer located between the galanin targeting moiety and the translocation domain.
Recombinant clostridial neurotoxins with increased duration of effect
This invention relates to novel recombinant clostridial neurotoxins exhibiting increased duration of effect and to methods for the manufacture of such recombinant clostridial neurotoxins. These novel recombinant clostridial neurotoxins comprise a random coil domain, and the methods comprise the steps of inserting a nucleic acid sequence coding for a random coil domain into a nucleic acid sequence coding for a parental clostridial neurotoxin and expression of the recombinant nucleic acid sequence comprising the random coil domain-coding sequence in a host cell. The invention further relates to novel recombinant single-chain precursor clostridial neurotoxins used in such methods, nucleic acid sequences encoding such recombinant single-chain precursor clostridial neurotoxins, and pharmaceutical compositions comprising the recombinant clostridial neurotoxin with increased duration of effect.
SORTASE-LABELLED CLOSTRIDIUM NEUROTOXINS
The present invention relates to a method for preparing a labelled polypeptide, the method comprising: a. providing a polypeptide comprising: i. a sortase acceptor site or a sortase donor site; ii. a non-cytotoxic protease or a proteolytically inactive mutant thereof; iii. a Targeting Moiety (TM) that is capable of binding to a Binding Site on a target cell; and iv. a translocation domain; b. incubating the polypeptide with: a sortase; and a labelled substrate comprising a sortase donor site or a sortase acceptor site, respectively, and a conjugated detectable label; wherein the sortase catalyses: conjugation between an amino acid of the sortase acceptor site of the polypeptide and an amino acid of the sortase donor site of the labelled substrate; or conjugation between an amino acid of the sortase acceptor site of the labelled substrate and an amino acid of the sortase donor site of the polypeptide; thereby labelling the polypeptide; and c. obtaining the labelled polypeptide. The invention also relates to polypeptides for labelling, labelled polypeptides, nucleic acids encoding said polypeptides, and methods of using and manufacturing said polypeptides.
