Abstract:
The present document relates to a system and method of commingling a low volume of a target solution with an array. For example, a quantity of the target solution and a quantity of an immiscible liquid may be introduced into a cavity having an array on an interior surface. The quantities of target solution and immiscible liquid do not fill the volume. Therefore, a gas is contained within the volume. The cavity is then agitated.
Abstract:
Methods and compositions for producing a labeled population of nucleic acids for use in an array-based comparative genome hybridization (CGH) assay are provided. In general, the methods involve cleaving a genomic source to produce a sample containing nucleic acid fragments, and end-labeling the nucleic acid fragments to provide a population of nucleic acids having a terminal label. Kits and systems for use in practicing the subject methods are also provided.
Abstract:
Methods and compositions for performing array-based CGH assays are provided. In general, the methods involve evaluating copy number of a genomic region by evaluating binding of distinguishably labeled populations of nucleic acids to a first CGH array in which: a) the populations of nucleic acids are labeled by a labeled primer and/or b) binding is assessed relative to binding of dye-swapped populations of nucleic acids to a second CGH array. Kits and systems for use in practicing the subject methods are also provided.
Abstract:
Alkalophilic and thermophilic cellulases having high stability to elevated temperatures and pH have been isolated from an organism of unknown species, which most closely resembles those in the Caldicellulosiruptor genus and which has been called by us, Tok7B.1, These cellulases have been cloned and expressed in a recombinant system, so that they can be produced in quantity. These are particularly useful in treating cellulosic materials including cotton-containing fabrics, as detergent additives, and in aqueous compositions. We also provide genomic DNA which can be used in recombinant expression vectors and expression systems to produce enhanced alkali and/or temperature stability properties in cellulases other than those specifically described.
Abstract:
A method of assessing the quality of an amplified nucleic acid sample is described. The method includes (a) separating the amplified nucleic acid sample to obtain a separation profile; (b) determining a first component of said separation profile corresponding to a first nucleic acid fraction; (c) determining a second component of said separation profile corresponding to a second nucleic acid fraction; and (d) assigning a quality value to the amplified nucleic acid sample based on the first component and the second component.
