  • substrate
  • Enzymes are adsorbed on an adsorbent powder in an aqueous medium and a water-miscible monomer is added thereto, and said monomer is polymerized to form a porous gel lump through which a substrate solution can freely pass. (google.com)
  • However, these polymers remarkably swell with water and therefore the inclusion mass is in the state of a gel lump that has no pores or voids, and therefore it is necessary to dry up the lump and pulverize it in order to convert it to a form in which the enzyme can contact with a substrate substance.

  • Substrate depletion is a risk where significantly higher levels of enzyme activity are present. (03964.com)
  • microbial
  • A greenhouse experiment was conducted for evaluation of ecological effects of transgenic melon plants in the rhizospheric soil in terms of soil properties, enzyme activities and microbial communities. (kspbtjpb.org)
  • These results clearly indicated that transgenic melon might change microbial communities, enzyme activities and soil chemical properties. (kspbtjpb.org)
  • nucleic acid
  • In a process for immobilization by passive fixation on a solid support of a nucleic acid fragment containing less than 100 nucleotides, the fragment is deposited on the support in the form of a derivative. (google.com)
  • The present invention relates to a process for the immobilization of a nucleic acid fragment on a solid support, the solid support thus obtained and its use, in particular in methods for the detection of target sequences containing a sequence complementary to the immobilized sequence. (google.com)
  • Once the nucleic acid is immobilized, the detectable non-nucleotide probe/target sequence complex, formed before or after the immobilization of the nucleic acid, can be detected, identified or quantitated under a wide range of assay conditions as a means to detect, identify or quantitate the target sequence in the sample.

  • adsorption
  • Firstly, insolubilisation can be achieved by physical adsorption of the enzyme on an inert support or on ion exchanger resins. (google.com)
  • However, with adsorption methods, there is a permanent danger of desorption of the enzyme occurring and the use of this method remains limited. (google.com)
  • bacteria
  • Functional (culture-based) and metagenome (sequence-based) analyses showed that bacteria involved in immobilization of heavy metals, rather than those engaged in mobilization, were the main driving force within the analyzed communities. (frontiersin.org)
  • Use of plant colonizing bacteria as chassis for transfer of N2-fixation to cereals. (montana.edu)
  • method
  • But in this method, the enzyme adsorbed thereon is easily desorbed as it is repeatedly used for reaction. (google.com)
  • For instance, a method which comprises polymerizing a water-soluble monomer suh as acrylamide in a solution containing an enzyme (K. Kawashima et al. (google.com)
  • known
  • Ames test a strain of Salmonella typhimurium that lacks the enzyme necessary for histidine synthesis is cultured in the absence of histidine and in the presence of the suspected mutagen and certain enzymes known to activate procarcinogens. (thefreedictionary.com)
