A microscope slide is a thin flat piece of glass, typically 75 by 26 mm (3 by 1 inches) and about 1 mm thick, used to hold objects for examination under a microscope. Typically the object is mounted (secured) on the slide, and then both are inserted together in the microscope for viewing. This arrangement allows several slide-mounted objects to be quickly inserted and removed from the microscope, labeled, transported, and stored in appropriate slide cases or folders etc.

A method and apparatus for an automated biological reaction system is provided. In the processing of a biological reaction system, there is a need for consistently placing an amount of liquid on a slide. In order to accomplish this, several methods are used including a consistency pulse and a volume adjust means. Moreover, in order to reliably operate an automated biological reaction system, the dispenser must be reliable, easy to assemble and accurate. Among other things, in order to accomplish this, the dispense chamber is substantially in line with the reservoir chamber, the reservoir chamber piston is removed, and the flow of liquid through the dispenser is simplified. Further, in order to operate the automated biological reaction system more reliably, the system is designed in modular pieces with higher functions performed by a host device and the execution of the staining operations performed by remote devices. Also, to reliably catalog data which is used by the automated biological reaction system, data is loaded to a memory device, which in turn is used by the operator to update the operator's databases. The generation of the sequence of steps for the automated biological reaction device based on data loaded by the operator, including checks to determine the ability to complete the run, is provided.

System and method for generating digital images of a microscope slide
An improved system and method for obtaining images of a microscope slide are provided. In one embodiment, a focus camera includes an optical sensor that is tilted relative to the focal plane of a scanning camera. A scan of a target region is performed, and multiple overlapping images of the target region are captured from a plurality of x-y positions. Each image contains information associated with multiple focal planes. Focus information is obtained from the images, and a desired-focus position is determined for the target region based on the focus information. The scanning camera then captures an image of the target region from the desired-focus position. This procedure may be repeated for selected regions on the microscope slide and the resulting images of the respective regions are merged to create a virtual slide.

Methods and compositions for the manipulation and characterization of individual nucleic acid molecules
InactiveUS6147198AQuick analysisQuick buildSugar derivativesMicrobiological testing/measurementMicroscope slideMap Location
A method for observing and determining the size of individual molecules and for determining the weight distribution of a sample containing molecules of varying size, which involves placing a deformable or nondeformable molecule in a medium, subjecting the molecule to an external force, thereby causing conformational and / or positional changes, and then measuring these changes. Preferred ways to measure conformational and positional changes include: (1) determining the rate at which a deformable molecule returns to a relaxed state after termination of the external force, (2) determining the rate at which a molecule becomes oriented in a new direction when the direction of the perturbing force is changed, (3) determining the rate at which a molecule rotates, (4) measuring the length of a molecule, particularly when it is at least partially stretched, or (5) measuring at least one diameter of a spherical or ellipsoidal molecule. Measurements of relaxation, reorientation, and rotation rates, as well as length and diameter can be made using a light microscope connected to an image processor. Molecule relaxation, reorientation and rotation also can be determined using a microscope combined with a spectroscopic device. The invention is particularly useful for measuring polymer molecules, such as nucleic acids, and can be used to determine the size and map location of restriction digests. Breakage of large polymer molecules mounted on a microscope slide is prevented by condensing the molecules before mounting and unfolding the molecules after they have been placed in a matrix.

Systems and methods for stitching image blocks to create seamless magnified images of a microscope slide
Scanned image portions of a virtual slide are stored in accord with a positional index metric associated to each image's location in a mosaic representation of the entire physical slide and a normalized correlation search is performed on next neighbor regional image blocks. A set of relative positional offset values and a correlation coefficient is determined for a regional image block and a next neighbor regional image block. A portion of the regional image blocks is viewed as a field of view of a display and a composite of the portion of regional image blocks is stitched together in accord with the set of relative positional offset values and the correlation coefficient, such that only the blocks comprising the portion are stitched. Moving the field of view of the display causes additional regional image blocks to be displayed, where image stitching is subsequently performed only with respect to the additional regional image blocks brought into the new field of view.

A microscope slide holding cassette includes a main body for surrounding and protecting microscopes, and shelves capable of holding the microscope slides. The shelves have support members that extend outwardly in order to support label ends of slides. Catches carried at the end of the support members are capable of limiting movement of the slides during transport of the cassette. To transport slides to different workstations, a pickup device can use a vacuum to pick up a slide without contacting areas of the slide that may have glue. The pickup device can load and unload the cassette. The pickup device can have a low-profile configuration in order to access relatively small spaces for processing flexibility.

A method and system for creating a digital, virtual slide having optimum image quality characteristics. Multiple regions of a physical slide are identified as well as at least two focus z-positions z1, and z2. Each region of the physical slide is scanned (imaged) at the first z position, so as to produce a first set of digital images of each defined region. Each region of the physical slide is also scanned (imaged) at the second z position, so as to produce a second set of digital images of each defined region. Each image of each set is evaluated against a focus quality metric and, for each region, either the first or second image, corresponding to that region, is selected that exhibits a focus quality metric corresponding to a desired focus quality. These images are then merged into a digital virtual slide. Additional focus z-positions may be included, and the multiple z-positions may be scanned seriatim, sequentially, and / or in overlapping fashion.
