    摘要： The interference of dehydroascorbic acid, an oxidation product of ascorbic acid, in analytical methods is reduced with the use of certain nitrogen-containing organic buffers. Dehydroascorbic acid tends to cause premature reduction of reducible compounds which are used to provide detectable species in the presence of an analyte. These organic buffers, as opposed to inorganic buffers, prevent premature reduction of the reducible compounds. An analytical method can be carried out in solution or in a dry analytical element.

    摘要： A multilayer analytical element for the determination of creatine kinase comprises a support having thereon, in order and in fluid contact, a registration layer and an isotropically porous spreading layer. The registration layer contains a binder material at a coverage of at least about 8 g/m.sup.2, which coverage improves the stability and keeping properties of the element in high humidity environments. This element is useful in an analytical method for determining total creatine kinase or any one of its isoenzymes, e.g. creatine kinase-MB.

    摘要： A method for preparing a blush polymer coating composition containing an immunologically reative species comprises milling the species and the other materials used in the composition to uniformly disperse the species therein. This coating composition can be used to prepare analytical elements for determining analytes (e.g. creating kinase-MB) whereby the effects of potential interferents are immunochemically removed. By milling the immunologically reactive species, e.g. antisera, into the coating composition, the resulting element has improved stability resulting in improved keeping in high humidity environments.

    摘要： A target nucleic acid can be amplified and detected using a water-insoluble capture probe having a short oligonucleotide (15-20 nucleotides) covalently attached to a polymeric particle, and one or more secondary oligonucleotides. The capture probe and secondary oligonucleotides are complementary to the target nucleic acid, although the sequences of complementarity are different. Moreover, each of the secondary oligonucleotides has a length which is equal to or greater than the length of the capture probe oligonucleotide. The secondary oligonucleotides are hybridized to the target nucleic acid either before or during hybridization of the target to the capture probe. The result is improved hybridization efficiency of capture probe and target nucleic acid.

    摘要： A biotinylated target nucleic acid can be isolated from a mixture of nucleic acids using a capture reagent comprising avidin. The targeted nucleic acid is complexed with avidin on a substrate and separated from uncomplexed materials. The complex is heated at above about 65.degree. C. for a suitable time to cleave the avidin-biotin bonds to release the desired targeted nucleic acid. Upon release, the targeted nucleic acid can be collected or detected in a suitable manner, such as with a complementary probe. This method is also useful for preparing single-stranded DNA for a number of uses.

    摘要： Reagents have been prepared from water-insoluble polymeric particles to which are covalently attached avidin, biotin or an avidin or biotin derivative. The polymeric particles comprise a polymer on at least the outer surface which is derived from at least one ethylenically unsaturated monomer having a reactive activated 2-substituted ethylsulfonyl, vinylsulfonyl or active halogen atom. Covalent attachment of avidin, biotin or an avidin or biotin derivative is effected either directly or indirectly through these reactive groups. The resulting reagent is useful in analytical elements and various analytical methods including agglutination and sandwich assays. The immobilized avidin, biotin or derivative can be used to complex with the corresponding biotin or avidin molecule which may be conjugated to a compound of biological interest.
