摘要:
An apparatus is provided to enable the direct gene transfer of genetic material into a target cell site (“microseeding”), as a means of obtaining long term expression of native or non-native polypeptides in a host. The apparatus includes a matrix of microneedles that oscillate at a predetermined frequency and receive the genetic material from a delivery system that is integrated with the apparatus.

Methods and systems for scanning a cytological specimen carried by a slide. Movement or positioning of a motorized stage of an automated screening system may be controlled manually by a user such that the user controls movement, e.g., controlling speed, position, and/or timing, of the motorized stage along a first scan line to controllably scan a first portion of the specimen along the scan line. The user may then index the motorized stage from the first scan line to the next scan line and manually control movement of the stage along the second scan line to controllably scan another portion of the specimen. Stage indexing may also be automatic such that the user does not control or initiate indexing.
摘要:
A system for preparing biological specimen slides comprises a slide preparation apparatus for preparing the specimen slides; a processor configured to control the slide preparation apparatus; and a data retrieval device coupled to the processor and configured to retrieve information from a storage device associated with the slide preparation apparatus or a component used by the slide preparation apparatus, wherein the processor selectively enables operation of the slide preparation apparatus based on the retrieved information.
摘要:
System and method for calibrating the orientation or arrangement of slides in a storage receptacle. A reflective marking is asymmetrically applied to a side or edge of a slide, forming reflective and non-reflective sections. Light is directed to the slide, and a sensor detects light that is reflected by the reflective sections and generates signal or data representing an orientation of the slide. A controller processes the signal or data to determine whether the slide is properly oriented on a tray in the storage receptacle, e.g., whether the slide is flat or at an angle, upside down, rotated. The marking can be reflective ink, paint or an adhesive. Reflective and non-reflective markings can also be formed by laser etching, polishing, or by frosting.
摘要:
Apparatus and methods for loading a tray containing a plurality of slides into an imaging system, and for verifying the alignment and orientation of the tray in the imaging system. A plurality of retainers secures the slides in recesses defined by the tray. An aligning projection on the tray interacts with an alignment component on the imaging system to verify the alignment and orientation of the tray in the imaging system and to disable the system if it cannot do so.
摘要:
Apparatus, system and method for preparing a sample of a biological specimen utilizing a filter tray having a data storage device. The data storage device stores data relating to filter compatibility, expiration, and processing steps and parameters. The storage device can be attached to or positioned within the filter tray. The storage device can also be interfaced to a sample processing system.

A detachable microscope pen mount for marking a microscope slide includes an attachment collar configured to secure to an objective lens, a lever secured to the attachment collar, a pen holder secured to the lever, and a pen secured to the pen holder and having a pen tip, where activating the lever moves the pen tip into a field of view and lowers the pen tip onto the microscope slide. Also disclosed is a method of marking a microscope slide includes identifying an object of interest in a field of view, positioning the object of interest in a center of the field of view, inserting a pen having a pen tip along a trough into a center of the trough, lowering the pen tip onto the microscope slide, and marking the microscope slide by tracing the inside of the center of the trough. Another method of marking a microscope slide includes identifying an object of interest in a field of view, positioning the object of interest in a center of the field of view, inserting a pen having a pen tip along a trough until it reaches an outside surface of a tube in the trough, lowering the pen tip onto the microscope slide, and marking the microscope slide by tracing the outside of tube.
