  • Peptidoglycan recognition proteins and their production
    Patent number: 6413729
    Abstract: A gene coding for a peptidoglycan recognition peptide (PGRP) is cloned, a recombinant vector into which said gene is introduced is obtained, and a transformant transformed with said recombinant vector is cultivated, thereby producing the PGRP in large amounts at high purity.

  • .alpha.-amylase assay using modified oligosaccharide and process for producing said modified oligosaccharide
    Patent number: 5319078
    Abstract: .alpha.-Amylase activity can be determined rapidly and precisely by using as a substrate a modified oligo-saccharide wherein a benzylozymethyl group or a halo-methyl group is bonded to the C.sub.6 position of non-reducing-end glucose residue and the reducing-end glucose residue is bonded to a group which exhibits an optically measurable change upon cleavage. Processes for producing such a compound are also disclosed.

  • Oligosaccharide derivatives suitable for .alpha.-amylase determination
    Patent number: 5319076
    Abstract: An oligosaccharide derivative of the formula: ##STR1## wherein R is --SR.sup.2, ##STR2## R.sup.1 is an optically detectable group, etc.; R.sup.2 is alkyl or substituted alkyl; and n is zero or 1-5, is effective as a substrate for measuring .alpha.-amylase activity and can be synthesized easily in high yield.
