Abstract: Disclosed is a nuclease resistant nucleotide compound capable of hybridizing with a complementary RNA in a manner which inhibits the function thereof, which modified nucleotide compound includes at least one component selected from the group consisting of MN3M, B(N)xM and M(N)xB wherein N is a phosphodiester-linked modified 2?-deoxynucleoside moiety; M is a moiety that confers endonuclease resistance on said component and that contains at least one modified or unmodified nucleic acid base; B is a moiety that confers exonuclease resistance to the terminus to which it is attached; and x is an integer of at least 2.

Abstract: Procedures and compositions for forming and stabilizing non stable branch migrated oligo- and polydeoxynucleotides utilizing a displacer which is either single stranded or partially double stranded and hybridized to a linker strand. The displacer may contain one or more modified nucleotides.

Abstract: Isolated nucleic acids which encode a thermostable protein that enhances specific binding of a thermostable mismatch binding protein to bulge loops in a heteroduplex nucleic acid and recombinant vectors comprising nucleic acid which encodes a thermostable protein that enhances specific binding of a thermostable mismatch binding protein to bulge loops in a heteroduplex nucleic acid are disclosed.

Abstract: A DNA sequence encoding the .delta.-amino levulinate type 2 gene, methods to detect the gene, diagnostic kits to detect the gene and recombinant vectors containing the type 2 gene sequence.

Abstract: A method is disclosed for detecting a polymorphism in the .delta.-aminolevulinate dehydratase gene which is associated with an altered susceptibility to lead poisoning. A point mutation which generates an MspI restriction endonuclease recognition site was found in the ALAD2 allele of the .delta.-aminolevulinate dehydratase gene which is not present in the ALAD1 allele. Kit containing primers for the amplification of the polymorphic region of the ALAD gene are provided.

Abstract: A method is disclosed to detect the presence of an analyte. The method involves forming a complex comprising the analyte and a binding entity. The binding entity comprises a first partner of an energy transfer system. The complex is then contacted with a reporting entity to form a unit. The reporting entity comprises a second partner of the energy transfer system. The first partner and the second partner are within Furster's radius of each other in the formed unit. The unit is irradiated with energy which can only be absorbed by one of said partners, namely, the energy donor, which then emits fluorescent energy. Some of this energy is absorbed by the other of said partners, namely, the energy acceptor, which also emits fluorescent energy. However, the fluorescent energy of the energy acceptor is of longer wavelength and in addition may be of substantially greater duration than the fluorescent energy of the energy donor.
