Cycling probe technology (CPT) is a molecular biological technique for detecting specific DNA sequences. CPT operates under isothermal conditions. In some applications, CPT offers an alternative to PCR. However, unlike PCR, CPT does not generate multiple copies of the target DNA itself, and the amplification of the signal is linear, in contrast to the geometric amplification of the target DNA in PCR. CPT uses a sequence specific chimeric probe which hybridizes to a complementary target DNA sequence and becomes a substrate for RNase H. Cleavage occurs at the RNA internucleotide linkages and results in dissociation of the probe from the target, thereby making it available for the next probe molecule. Integrated electrokinetic systems have been developed for use in CPT. Bhatt, R; Scott, B; Whitney, S; Bryan, R; et al. (1999).

A flow cell which can be used in the synthesis of DNA probes on an active surface of the substrate includes a base having a central window opening and a registration surface against which the substrate may be mounted. A gasket having a central opening defining an active area is mounted on the active surface of the substrate and has inlet and output extension openings which extend away from the central opening. A press block is engaged against the gasket to fully enclose an active volume between the press block, the peripheral walls of the central opening in the gasket, and the active surface of the substrate. A press is mounted to the base to selectively press the press block against the gasket and hold it in position. Channels in the press block extend to the extension openings in the gasket to allow flow of reagent into and out of the active volume, which is confined to the thickness of the gasket and can thus be minimized. The press may include a press screw which can be turned to engage against the
File probe level tells file opener (its probe method to be exact), how hard it should try to recognize the type of the file. File openers may ignore this or support only some probe levels, but if specifies "reccomened" behaviour. Before opening any file we detect its type by calling probe for every registered file opener (in order of priority) and passing GO_FILE_PROBE_FILE_NAME as probe level. If none of them recogizes the file, we increase probe level and try again.... ...

OligoWiz 2.0 is a powerful tool for microarray probe design that allows for integration of sequence annotation such as exon/intron structure, UTR regions, TSS, etc. In addition to probe selection according to a series of probe quality parameters, cross-hybridization, Δ Tm, position in transcript, probe folding and low-complexity, the program facilitates automatic placement of probes relative to the sequence annotation. The program also supports automatic placement of multiple probes per transcript. Together these facilities make advanced probe design feasible for scientists inexperienced in computerizes information management. Furthermore, we show that probes designed using OligoWiz 2.0 give rise to consistent hybridization results ...

A probe driving method and a probe apparatus for bringing a probe into contact with the surface of a sample in a safe and efficient manner by monitoring the probe height. Information about the height of the probe from the sample surface is obtained by detecting a probe shadow (54) appearing immediately before the probe contacts the sample, or based on a change in relative positions of a probe image and a sample image that are formed as an ion beam is irradiated diagonally.

Probes are mapped using two different programs according to probe length - short probes (Bowtie2 alignment, while longer probes (,200bp) are mapped using Exonerate. The reason for processing the probes differently according to length is based on the need to rapidly map large numers of probes across many different species. The majority of VectorBase probes are short (Bowtie2 alignments which are significantly faster to perform than Exonerate. Longer probes (,200bp) are often derived from cDNA/EST sequences and span multiple exon/intron junctions - these probes are mapped with Exonerate as it detects these junctions in an accurate and sensitive manner. Probes are mapped against both the genomic sequence, and the transcripts. Where high quality hits are found on the transcript but not on the genomic sequence the probe sequence is projected from the transcript sequence back into genomic coordinates.. Alignments are stored as described by the Ensembl microarray probe mapping pipeline, but only probes ...
Southern blotting is an experimental procedure where DNA, from a genomic or other source, is digested with a restriction enzyme and then separated by size using gel electrophoresis. The fragments are transferred from the gel onto a membrane (blotted) which is then incubated with a labelled single-stranded DNA probe. Such a procedure allows one to locate a particular sequence of DNA within a complex mixture of DNA. From a gene targeting perspective, Southern blotting can be used to detect whether a targeting event has successfully taken place. Designing a good Southern blot probe for a particular gene or locus involves finding a stretch of DNA sequence at that locus, generally 500-1000bp long, that has the desirable qualities of being unique to that locus, with little or no repetitive DNA content. Molecular biologists tend to design their probes manually, by excising portions of genome sequence from online genome browsers (such as such as Ensembl) and then pasting them into a genome-search ...

To exploit fully the potential of current sequencing technologies for population-based studies, one must enrich for loci from the human genome. Here we evaluate the hybridization-based approach by using oligonucleotide capture probes in solution to enrich for approximately 3.9 Mb of sequence target. We demonstrate that the tiling probe frequency is important for generating sequence data with high uniform coverage of targets. We obtained 93% sensitivity to detect SNPs, with a calling accuracy greater than 99%.

Our Specialized Laser Unit: ProHealth Physiotherapy is using medical grade laser built by Theralase (www.theralase.com). The advanced laser controller unit can be connected to 3 different probes, depending on the therapeutic effect desired: a single probe, a triple probe, and a multiple probe. The single (point) probe has only one invisible laser emitter, and is used for very local applications or needle-free acupuncture. The triple probe has one invisible laser emitter (905 nm) and two visible red emitters (660nm). The multiple probe has 5 invisible laser emitters and 4 visible red laser emitters. The combination between the super pulsed invisible laser light (905 nm) and the continuous wave visible red laser light (660nm) allow simultaneous superficial and deep (up to 4") laser treatment, thus activating all three known cellular pathways ...
Figure S1. (A) Pilot microarray. miRNA probes were printed to test hybridization and wash conditions. Samples for hybridization to the array were individually labeled with either (Cy3, green) or (Cy5, red), mixed in equamolar amounts, and hybridized to the array at the temperatures indicated. Specific hybridization was observed as either red or green spots on the array, whereas crosshybridization was observed as shades of yellow. Each miRNA probe was selected to test the resolution of the array for single and multiple mismatches between probe sequences. For example, fug-mir-197 and hsa-mir-197 test the resolution of single nucleotide differences within three nucleotides of the 3_ end of the probe sequence. Test probes were also designed to span a range of melting temperatures. As the hybridization temperature was increased, the specificity of the test array was generally improved to a point near 55-60 C (see hsa-mir-148 and hsa-mir-136). (B) Representative sample grid of a microarray. A more ...
