Abstract: Multi-array systems useful for performing assays on multiple biomolecule arrays simultaneously while minimizing sample volume are provided. Apparatuses and kits comprising the multi-array systems also provided. Methods of using the multi-array systems in assays such as hybridization arrays are also provided, as well as methods of producing the multi-array systems.

Abstract: The present invention relates to the identification of the over expression of certain genes encoding certain secreted and membrane-bound proteins in breast, lung, colon and kidney cancers. Knowledge that these genes are over expressed in the cancers is useful for the detection, diagnosis, prevention and treatment of the specific cancers.

Abstract: The present invention provides novel methods for detection of gene. A method for detecting RNA molecules of interest in which oligonucleotide primers uniquely complementary to specific RNA molecules are used as primers for reverse transcribing target RNAs with reverse transcriptase, or any enzyme that possesses reverse transcription activity, is provided. The invention eliminates the need for labeling or converting the target RNA by incorporating detectable labels in the elongation product of reverse transcription of the probe-bound target RNA in the sample.
