    摘要: The invention provides a process wherein a biotinylated oligonucleotide primer and an oligonucleotide primer which has not undergone biotinylation are used when amplifying a DNA sequence to facilitate separation of the DNA strands following the polymerase chain reaction process. The biotinylation/PCR product is then exposed to a support which will selectively bind the biotinylated strand to allow selective elution of the product.

    摘要: The present invention provides methods and compositions for conferring selective death on cells expressing a specific target precursor messenger RNA (selective target pre-mRNA). The compositions of the invention include pre-trans-splicing molecules (PTMs) designed to interact with a target precursor messenger RNA molecule (target pre-mRNA) expressed within a cell and mediate a trans-splicing reaction resulting in the generation of a novel chimeric mRNA molecule (chimeric mRNA) capable of encoding a light producing protein or enzyme. Cell death is further mediated by the presence of a photosensitizer which upon photoactivation produces cytotoxicity.

    摘要: The invention relates to polymorphic markers (two tetranucleotide, one dinucleotide repeat polymorphisms, 27 markers characterized by primer pairs 1A-27A, and five markers characterized by primer pairs 1B-5B that are useful for human individualization. Applications are in forensic medicine and for paternity and prenatal screening as well as genetic mapping. These markers are characterized by sets of oligonucleotide primers according to the invention useful in PCR amplification and DNA segment resolution. The invention further relates to an assay for measuring the subtle differences in genetic material regarding an added or omitted set of dinucleotide or tetranucleotide repeat polymorphisms which comprises obtaining an amount of nucleotide segments effective for testing, amplifying the segments by the PCR procedure using at least one primer nucleotide sequence according to the present invention, resolving the amplified segments using gel electrophoresis, and comparing the resolved segments by autoradiography to observe the differences in migration patterns due to structural differences. The assay according to the invention is easy to perform and results can be obtained within 24 hours. It is not uncommon for results to be available within 3-4 hours. Accordingly, the invention also relates to an improved PCR procedure and a PCR assay kit which comprise nucleotides according to the invention.
