VizX Labs, Aushon BioSystems

VizX Labs last week released the latest version of its web-based GeneSifter analysis tool.
The update includes new raw data-exporting features; Tukey post-hoc analysis to identify where the significant gene expression differences occur in data; and data management upgrades, including support for new Illumina BeadChip data file formats, support of Affymetrix ST GeneChips, and an updated version of BioConductor.
VizX said that GeneSifter users can access the upgrades immediately by logging into their accounts.

Aushon BioSystems this week expanded its microarray service line to include offerings related to reverse-phase arrays. Previously, Aushon offered RPA print services through its Custom Microarray Printing Services, but the firm has now added downstream array processing and data analysis.
Unlike forward phase arrays, in which antibodies or recombinant proteins are printed onto substrates, reverse phase arrays are created by depositing the samples to be analyzed, such as cell/tissues lysates or blood plasma, directly onto substrates. Aushon said that such arrays are useful for high-throughput analysis of protein levels and post-translational modifications.
