With this arrangement, it is possible to provide white water-absorbable resin with better water absorbing rate, keeping or without significantly losing the other properties (permeability potential, bulk specific gravity, surface tension, absorbency against pressure, impact resistance, etc.

  • Patent number: 7964559
    Abstract: The present invention relates, e.g., to an isolated polypeptide from a cyanobacterium, Microcystis viridis, which binds specifically to an oligosaccharide comprising the tetrasaccharide Man-alpha-(1?6)Man-beta (1?4) GlcNAc-beta(1?4)GlcNAc. The polypeptide can be obtained, for example, from a cell that expresses a recombinant nucleic acid that encodes a MVL-like polypeptide. The invention also relates to an isolated polypeptide comprising one or more copies of the sequence GPLWSNXEAQXXGPX (SEQ ID NO: 1) and/or one or more copies of the sequence FTGQWXTXVEXXMSV (SEQ ID NO: 2), wherein the polypeptide binds specifically to the above-mentioned oligosaccharide. Conjugates comprising such polypeptides and an effector molecule are also disclosed, as are methods of using such polypeptides or conjugates, e.g., for inhibiting infection by a virus, such as HIV, or for removing a virus, such as HIV, from a sample, such as a bodily fluid or an inanimate object.
