摘要： The invention encompasses methods for enriching for and identifying a polymorphism within a nucleic acid sample either by separating a subset of a nucleic acid sample or by selectively replicating a subset of a nucleic acid sample such that the polymorphism is contained within a nucleic acid population with reduced complexity, and then identifying the polymorphism within the enriched nucleic acid sample. Methods also are disclosed for enriching for and identifying a polymorphism by contacting a nucleic acid sample that includes a subset of nucleic acid molecules having a sequence that binds to a sequence-specific binding activity with a molecule having a sequence-specific binding activity under conditions which permit specific binding, such that the subset of nucleic acid molecules bound to the activity is enriched for nucleic acid molecules having the sequence recognized by the sequence-specific binding activity, and detecting a polymorphism with respect to a reference sequence in the subset of nucleic acid molecules.

摘要： Methods and apparatus for direct detection of chemical reactions are provided. In a preferred embodiment, electric charge perturbations of the local environment during enzyme-catalyzed reactions are sensed by an electrode system with an immobilized target molecule. The target molecule is preferably DNA. The charge perturbation caused by the polymerase reaction can uniquely identify a DNA sequence. The polymerization process generates local perturbations of charge in the solution near the electrode surface and induces a charge in a polarazible gold electrode. This event is detected as a transient current by a voltage clamp amplifier. Detection of single nucleotides in a sequence can be determined by dispensing individual dNTPs to the electrode solution and detecting the charge perturbations. Alternatively, multiple bases can be determined at the same time using a mix of all dNTPs with subsequent analysis of the resulting signal. The initial enzyme attachment to the DNA molecule can be detected prior to polymerization, with electrode capacitance measurement using the same voltage-clamp amplifier. This technique and device may be adapted to other reaction determinations, such as enzymatic reactions, other electrode configurations, and other amplifying circuits.

摘要： Described here is an automated robotic device that isolates circulating tumor cells (CTCs) or other biological structures with extremely high purity. The device uses powerful magnetic rods covered in removable plastic sleeves. These rods sweep through blood samples, capturing, e.g., cancer cells labeled with antibodies linked to magnetically responsive particles such as superparamagnetic beads. Upon completion of the capturing protocol, the magnetic rods undergo several rounds of washing, thereby removing all contaminating blood cells. The captured target cells are released into a final capture solution by removing the magnetic rods from the sleeves. Additionally, cells captured by this device show no reduced viability when cultured after capture. Cells are captured in a state suitable for genetic analysis. Also disclosed are methods for single cell analysis. Being robotic allows the device to be operated with high throughput.

摘要： A DNA microarray, preferably in the form of a chip, contains probes which hybridize to generate primers capable of amplifying approximately 89 HPV types. These target the E1 region of the gene. The design of the chip allows for the detection of any known HPV type, based on a unique probe sequence derived from the HPV E1 region. The present assay utilizes a number of primers that can amplify from about one to six different types of HPV. A large number of primers can be used together. After amplification, the amplicons are contacted with specific probes that are unique for each HPV type. The array further employs a control sequence, which normalizes variability due to sample size.

摘要： A rapid diagnostic assay for influenza virus, particularly avian influenza and more particularly H5N1, is described. The assay is based on amplification of a significant portion of the hemagglutinin (HA) gene and sequencing of several loci within the HA gene, using techniques which can obtain real time sequence information from multiple sites of a target DNA, in particular pyrosequencing and bioluminescence regenerative cycle. The assay contemplates the use of information-rich subsequences within the HA gene, e.g., (1) a glycosylation sequon; (2) receptor binding site; and (3) HA1/HA2 cleavage site. Other subsequences for sequencing include strain and clade markers, which vary among H5N1 strains.
