Abstract: In one embodiment, a method for analyzing data generated by probe arrays is described that comprises receiving user selections of two or more data files and an identification of one or more subsets of intensity values acquired from a biological probe array. The method includes iteratively opening each data file, identifying the selected subset of intensity values associated with each open data file, determining parameters for processing, storing the parameters and the identified intensity values, and closing the open data file prior to the subsequent iteration. The method then includes processing the stored intensity values using the parameters to identify one or more biological events.

Abstract: A heat labile alkaline phosphatase enzyme and methods of using the same and kits including the same are disclosed. Specifically, a nucleotide sequence of, peptide sequence of, methods of using, and kits comprising, a heat labile alkaline phosphatase isolated from Colwellia psychrerythraea are provided. Methods of over-expression and purification of the recombinant alkaline phosphatase and mutants thereof are also disclosed. Methods of over-expressing and purifying commercially useful quantities of active recombinant heat labile alkaline phosphatase fusion enzymes from C. psychrerythraea, wherein the fusion enzymes comprise one or more heterologous leader sequences are disclosed. The disclosed C. psychrerythraea heat labile alkaline phosphatase has properties similar to shrimp alkaline phosphatase and can be substituted for shrimp alkaline phosphatase in assays involving the same.

Abstract: The present invention provides massively parallel oligonucleotide synthesis and purification for applications that utilize large collections of defined high-fidelity oligonucleotides (e.g., from about 101 to about 105 different sequences, generally between 25-160 bases in length).
Abstract: In one aspect of the invention, systems, methods, and devices are provided for creating microfluidic and nanofluidic structures. In some embodiments, such systems, methods, and devices are used to create features with high aspect ratios in lab cards.
Abstract: A computer program product, and related systems and methods, are described that processes emission intensity data corresponding to probes of a biological probe array. The computer program includes a genotype and statistical analysis manager that determines absolute or relative expression values based, at least in part, on a statistical measure of the emission intensity data and at least one user-selectable statistical parameter. The analysis manager may also determine genotype calls for one or more probes based, at least in part, on the emission intensity data. The analysis manager may further display the absolute or relative expression values based, at least in part, on at least one user-selectable display parameter and/or a measure of normalized change between genotype calls. The measure of normalized change may be based, at least in part, on a comparison of genotype calls and a reference value.
