  • Patent number: 6737389
    Abstract: A next textile treatment where the present method can be used to remove contaminants from the textile concerns rewashing. As already observed above, after dyeing textile with reactive dyestuffs, a considerable amount of dyestuff, particularly hydrolyzed dyestuff, is left behind on the textile. Because the hydrolyzed dyestuff is not fast to washing, it should be removed to provide a textile with sufficient washing fastness. In a rewashing treatment of textile dyed with reactive dyestuff, the textile is first rinsed with water to remove alkali and salt. Thereupon, it is rewashed, with the fructan polycarboxylic acid being metered in the form of a 25-40% solution in an amount of 1-3 g/l of water. Rewashing preferably takes place at a temperature of 95-100° C. for a period of 10-30 minutes. After rewashing, the textile is again rinsed with water to remove residues of the hydrolyzed reactive dyestuff.

  • Patent number: 6692942
    Abstract: The present invention is directed to a method of in vivo and ex vivo gene delivery, for a variety of cells. More specifically, it relates to a novel carrier system and method for targeted delivery of nucleic acids to mammalian cells. More specifically, the present invention relates to carrier system comprising single-chain polypeptide binding molecules having an a region rich in basic amino acid and having the three dimensional folding and, thus, the binding ability and specificity, of the variable region of an antibody. The basic amino acid rich region can comprise oligo-lysine, oligo-arginine or combinations thereof. Such preparations of modified single chain polypeptide binding molecules also have ability to bind nucleic acids at the region rich in basic amino acid residues. These properties of the modified single chain polypeptide binding molecules make them very useful in a variety of therapeutic applications including gene therapy.
