    摘要: Techniques for processing gene expression data and predicting gene relationships are provided. More specifically, a method for processing gene expression ratios may include discretizing a first expression ratio for a first gene and a second expression ratio for a second gene for each of a plurality of experiments into one of three indications, calculating the probability that the combination of the discretized expression ratios for each of the plurality of experiments arises by random chance, and determining whether the first gene and the second gene are related.

    摘要: A microfilter utilizing the principles of tangential flow to prevent clogging, and sloped channel sides to overcome surface tension effects is provided which has feed inlet and exit connected by a feed flow channel; a barrier channel parallel to the feed flow channel, and a filtrate collection channel parallel to the barrier channel so that liquid can flow from the feed flow channel through the barrier channel which is too small to accommodate the particles, into the filtrate collection channel, and from then through a filtrate flow channel to a filtrate exit. Several picoliters of cell-free plasma are recovered from one drop of blood for analysis.

    摘要: This invention provides an extraction device and a method for extracting desired particles from a sample stream containing the desired particles. The device has a sample stream inlet, an extraction stream inlet, and an extraction channel in fluid communication with the sample stream inlet and the extraction stream inlet. The extraction channel is for receiving a sample stream from the sample stream inlet in adjacent laminar flow with an extraction stream from the extraction stream inlet. A sequestering material within the extraction channel captures desired particles in the extraction stream. A by-product stream outlet in fluid communication with the extraction channel receives a by-product stream comprising at least a portion of the sample stream form which desired particles have been extracted. A product outlet in fluid communication with the extraction channel receives a product which has the sequestering material and at least a portion of the desired particles.
