摘要:
The invention provides methods and compositions for hybridizing at least one molecule to an RNA target. The invention may, for example, eliminate the use of, or reduce the dependence on formamide in RNA hybridization applications. Compositions for use in the invention include an aqueous composition comprising at least one nucleic acid sequence and at least one polar aprotic solvent in an amount effective to enable hybridization to RNA.

This invention describes a cartridge pump and dispensing assembly for applications where cartridges containing liquid reagents are interchanged often. The cartridge pump has a reagent reservoir which directly empties into a metering chamber. A valve is at each end of the metering chamber. The two valves are aligned in the same direction so as to allow unidirectional liquid flow. The metering chamber is made of a compressible material, such as flexible tubing, so that when an external compression is applied to the chamber, the liquid contained therein is forcibly expelled. As the compression is removed, the metering chamber resumes its former shape and draws liquid into the chamber from the reagent reservoir. A dispensing assembly with electromechanical actuators for compression of the metering chamber and a sensor for sensing the amount of liquid contained within the reagent reservoir are also shown.

Systems and methods in accordance with embodiments of the present invention allow for the automatic control and scheduling of a staining apparatus for biological samples on slides present within the apparatus. In some embodiments, the actions of a robot coupled to the staining apparatus, which performs some of the staining tasks on the individual slides in accordance with their respective protocols, may be prioritized and scheduled. In some embodiments, the scheduling may result in increasing or maximizing the throughput of slides. In some embodiments, robot scheduling ensures that the individual slides are processed substantially within the tolerances specified by their respective protocols. In some embodiments, the robot scheduler may respond to spontaneous user actions and adaptively schedule or re-schedule robot actions.
摘要:
The present invention concerns a method and an apparatus for automatic staining of at least one tissue sample accommodated on a slide by applying reagents. The system may include at least one slide provided in a slide rack, a fluid containment element, a slide holder, a vertical slide positioner to pivot the slides to a vertical position, and a slide immerser element to immerse the vertical slide into a fluid containment element or even a dip tank. By pivoting the slides from a horizontal to a vertical position, an automated method and apparatus for carrying out a pretreatment in an automated staining apparatus may be provided. The pivoting of slides may ensure an appropriate orientation of the slides for both the pretreatment and the staining processes.

摘要:
An automated slide stainer with slides mounted in a horizontal position on a rotary carousel. Reagents and rinse liquids are automatically dispensed onto tissue sections or cells mounted on slides for the purpose of performing chemical or immunohistochemical stains. The rinse liquids are removed by an aspiration head connected to a source of vacuum. Individual slides or groups of slides are supported on flat heating stations for heating to individual temperatures. Temperature control electronics on the carousel are controlled by a user interface off of the carousel.
摘要:
A novel method for detecting chromosome aberrations is disclosed. More specifically, chromosome aberrations are detected by in situ hybridisation using at least two sets of hybridisation probes, at least one set comprising one or more peptide nucleic acid probes capable of hybridising to specific nucleic acid sequences related to a potential aberration in a chromosome, and at least one set comprising two or more peptide nucleic acid probes capable of hybridising to specific nucleic acid sequences related to another potential aberration in a chromosome. In particular, the method may be used for detecting chromosome aberrations in the form of breakpoints.
摘要:
Novel compounds carrying ligands capable of binding to counter receptors on relevant target cells are disclosed. The compounds possess a number of advantageous features, rendering them very suitable for a wide range of applications, including use as detection systems, detection of relevant target cells as well as a number of other methods. In particular, novel MHC complexes comprising one or more MHC molecules are disclosed. The affinity and specificity of the MHC-peptide complexes are surprisingly high. The possibility of presenting to the target cells a plurality of MHC-peptide complexes makes the MHC complexes according to the present invention an extremely powerful tool e.g. in the field of therapy and diagnosis. The invention generally relates to the field of therapy, including therapeutic methods and therapeutic compositions. Also comprised by the present invention is the sample-mounted use of MHC complexes and MHC multimers.
