    Abstract: Provided are methods, kits and arrays for carrying out relative measurement of an analyte of interest in a biological sample. As specifically exemplified, there is an array of stabilized, desiccated cDNA preparations, each at a defined location within the array, where those cDNAs were prepared from cells treated with a particular condition believed to modulate at least one gene of interest. Detection can be via Real Time Polymerase Chain Reaction using an appropriate reaction mixture and primers specific for a coding sequence of interest, and a greater relative amount of a RT PCR product from a control preparation reflects greater gene expression in response to the test condition whereas a lower amount of RT PCR product reflects an inhibitory effect on expression of the coding sequence of interest as a result of the application of the test condition.

  • Publication number: 20100222226
    Abstract: To provide an electronic component mounting system and an electronic component mounting method which can prevent a mounting failure due to positional error in a height direction of a substrate and ensure mounting quality. The electronic component mounting system includes a plurality of electronic component mounting devices connected to one another and mounts an electronic component on a substrate to manufacture a mounting substrate. A print test device for testing the substrate after solder printing measures a height position of a height measurement point set on the upper surface of the substrate 4 by a height measuring machine 22 and outputs a measurement result as substrate height data. In a component placing step using an electronic component placing device, a control parameter for controlling a component placing operation of the placing head 32 is updated.

  • Publication number: 20100204056
    Abstract: A method for fabricating and assessing the quality of printing on substrates used for chemical or biological array testing, and method for ascertaining relative consistency of the deposit reproducibility is described. Generally, the method involves: providing a substrate, providing a solution mixture of a capture moiety and a colorant; depositing an amount of said solution mixture onto said substrate, monitoring the substrate such that the visible indicator colorant manifests in a co-extensive fashion as with the capture moiety on the substrate. In another aspect, the invention relates to a sensor or assay device comprising a physical complex of a number of capture agents and an amount of colorants adhere to least a part of a surface of a substrate.

  • Publication number: 20100144553
    Abstract: The invention relates, in part, to the improved analysis of carbohydrates. In particular, the invention relates to the analysis of carbohydrates, such as N-glycans and O-glycans found on proteins and saccharides attached to lipids. Improved methods, therefore, for the study of glycosylation patterns on cells, tissue and body fluids are also provided. Information from the analysis of glycans, such as the glycosylation patterns on cells, tissues and in body fluids, can be used in diagnostic and treatment methods as well as for facilitating the study of the effects of glycosylation/altered glycosylation. Such methods are also provided. Methods are further provided to assess production processes, to assess the purity of samples containing glycoconjugates, and to select glycoconjugates with the desired glycosylation.
