  • Publication number: 20190241851
    Abstract: The invention concerns a cassette (16) for cell culture comprising:—an at least partially rigid housing (90) internally defining an internal space inside which a cell culture bag (100) defining an internal volume is arranged and attached,—conduits (36, 38) each connected at one end to the internal volume of the bag (100) and each having a second end situated outside the housing (90),—valves (128, 130) for enabling/preventing the flow of fluid through the conduits (36, 38) that are mounted on the housing (90).

  • Publication number: 20060199183
    Abstract: The invention relates to fields of use of unlabelled polynucleotide probes able to form hairpins, the biochips comprising such probes and methods allowing use thereof. The present invention also concerns methods for designing such probes and biochips. More particularly, the invention concerns the use of such unlabelled probes and biochips for manipulating and analysing polynucleotide sequences and optionally molecules which are associated therewith. This invention further concerns methods for preparing and use such probes and biochips for analysing mutations, sequencing, detection of alternative splicing variants, gene expression analysis, analysis of allelic imbalances and loss of heterozygosity and the detection of any nucleic acid present in organisms or residues from said organisms.

  • Patent number: 6312906
    Abstract: A fluorescently labeled nucleic acid having a hairpin structure between the fluorophore label and a point of attachment to a solid phase is useful as a probe to detect nucleic acid from a sample. The solid phase quenches the fluorophore label when the hairpin structure exists but this quenching is relieved by duplex formation between probe and a sample oligonucleotide. Probes for specific nucleic acid sequences can be immobilized as arrays on solid phase surfaces for detection of multiple nucleic acid sequences simultaneously from electrophoresis gels and from aqueous solutions. These probes and methods for their use can be combined with known solid phases, particularly those used for plasmon surface detection and electron transfer detection of nucleic acid. The probes can be washed and reused, and have other advantageous features over known probe methods.
