    摘要: This invention relates generally to the field of nucleic acid analysis. In particular, the invention provides a method for typing a target gene, using, inter alia, a chip comprising a support suitable for use in nucleic acid hybridization having immobilized thereon an oligonucleotide probe complementary to said target nucleotide sequence and at least one of the following oligonucleotide control probes: a positive control probe, a negative control probe, a hybridization control probe and an immobilization control probe. Oligonucleotide probes or probes arrays for typing a HLA target gene are also provided.

    摘要: The invention provides a method for identification of alleles. In this method, genomic DNA is used as target. Multiple allele-specific PCR amplification are carried out with a group of primers comprising one or more allele-specific primers for a target gene, a universal primer, and a common primer; and a DNA polymerase without 5′ to 3′ exonuclease activity. The PCR products are hybridized with tag probes immobilized on a DNA chip. Results are determined based on the signal intensity and the position of the probe immobilized on the array. Each allele-specific primer comprises a unique tag sequence at the 5′ end. Each tag probe immobilized on the DNA chip comprises a sequence identical to its corresponding tag sequence; and each tag probe hybridizes only with the complementary sequence in the PCR amplification product.

    摘要: A microarray-based assay is provided, which is used for analyzing molecular interactions, including polynucleotides, polypeptides, antibodies, small molecule compounds, peptides and carbohydrates. Such method comprises labeling a target molecule with a luminophore, coupling the target molecule to a particle, and binding to a probe molecule on microarray. In particular, multiplexed genetic analysis of nucleic acid fragments can be implemented. Specific genes, single nucleotide polymorphisms or gene mutations, such as deletions, insertions, and indels, can be identified. This technology, with high sensitivity, enables the detection and interpretation of molecular interactions in an efficient way.
