Title: Method for normalizing the relative intensities of detection signals in hybridization arrays
Inventor: LEBLANC BENOIT
IPC: C12Q1/68
Filed: 2001-12-21
Abstract: The present invention relates to rRNA-derived cDNA used as an internal standard or control to achieve normalization of hybridization signal detection in microarray biochip technology. Analysis of data obtained from a laser scanner during DNA microarray experiments first requires image processing.  However, the data generated for the arrayed genes must be normalized before differentially expressed genes can be identified. Normalization is necessary to compensate for differences in labelling and detection efficiencies for the labels and for differences in the quantity of starting RNA from the samples examined in the assay. Because of its relatively invariant expression across tissues and treatments, 18S and 28S ribosomal RNAs are ideal internal controls for quantitative RNA analysis. A way to circumvent the technical difficulties of using ribosomal RNA as a control, because of its overabundance relative to that of other RNAs, is described and claimed in the present application.  Improved methods, arrays and kits comprising arrays and free unlabelled ribosomal probes, are objects of this invention. The unlabelled ribosomal probes are used to compete out the excess or ribosomal nucleics present in a sample wherein all cDNA species of the sample are labelled before being placed in contact with the arrays.

Patent CA-2412409-A1 (CA)
Title: Disposable syringe
Inventor: SHUE MING-JENG
IPC: A61M5/32
Filed: 2002-11-20
Abstract: A disposable syringe includes a tubular barrier member retained in a rear passageway of a barrel. A tubular needle seat for fixing a needle cannula is retained on the barrier member, and abuts against an abutment wall in the front passageway of the barrel while the needle cannula is disposed outwardly of the barrel. A plunger is slidable in the rear passageway, and has a seal member to seal a cavity confined in a plunger body and containing a fluid at a reduced pressure. When a pushing force applied to the plunger body moves the barrier member against the first and second frictional forces, the needle seat is released, and the seal member is ruptured, so that the needle seat and the needle cannula are suctioned into the cavity due to the pressure difference between the ambient atmosphere and the reduced pressure.

Ces lipides sont localisés à l'extérieur de l'embryon proprement dit, à l'intérieur de la zone pellucide, ce qui permet de neutraliser les effets nuisibles qui empêchent le développement embryonnaire ultérieur. Ces embryons peuvent être cryopréservés par vitrification ou par congélation classique. Après récupération et réhydratation, les zones pellucides sont éliminées, et les embryons intacts viables sont transférées dans des femelles receveuses.
