IPC: C12Q1/68
Filed: 2002-12-05
Abstract: The invention describe protein arrays and their use to assay, in a parallel fashion, the protein products of highly homologous or related DNA coding sequences. By highly homologous or related it is meant those DNA coding sequences which share a common sequence and which differ only by one or more naturally occurring mutations such as single nucleotide polymorphisms, deletions or insertions, or those sequences which are considered to be haplotypes (a haplotype being a combination of variations or mutations on a chromosome, usually within the context of a particular gene). Such highly homologous or related DNA coding sequences are generally naturally occurring variants of the same gene. Arrays according to the invention have multiple for example, two or more, individual proteins deposited in a spatially defined pattern on a surface in a form whereby the properties, for example the activity or function of the proteins can be investigated or assayed in parallel by interrogation of the array.

IPC: D06P3/00
Filed: 2002-12-13
Abstract: A process for the continuous dyeing of plastic films, such as polyethylene terephthalate, is characterized by passing the film through a dye bath comprised of dye stuffs dissolved, suspended or dispersed in a liquid carrier comprised at least in part of a polymer, preferably a polyol, having at least one free hydroxyl group and a molecular weight within the range of from about 200 to about 600. The hydrogen bonding provided by the hydroxyl group, together with the high molecular weight and high boiling point of the polyol, mitigate against migration of the dye stuff out of the film, i.e., fading of the film, and impart long lasting color fastness to the film. Rapid diffusion of the dye bath into the film is enhanced by thermal and ultrasonic energization of the bath.

The first and second receptacles have a substantially identical pressure, while the storage tank is generally maintained at atmospheric pressure. The gear mechanism operates at atmospheric pressure if the gear mechanism fails to reduce internal pressure in the casing.
