摘要:
An apparatus and method for transferring plurality of samples from one sample container to another one is disclosed wherein each sample is randomly accessible and can be “cherry picked”. The disclosed method of actuation allows for using a smaller number of actuators than the number of sample transferring channels or pins and thereby simplifies the design and control of the sample transferring apparatus.
摘要:
A microdeposition pin having a contact surface with at least one concave edge for creating microarrays and the like. The microdeposition pin may be used either alone or with a plurality of microdeposition pins in conjunction with a holder. The concave edge of the pin is especially adapted for helping to control the spreading of a deposited material. By selectively controlling the spread of the reagent composition from the microdeposition pin, the flow of the reagent composition from the deposition target area may be reduced. Sensor strips having raised substrate features with limited or no spreading of the reagent composition beyond the target area are disclosed.

摘要:
The invention provides an apparatus and a method of processing a biological and/or chemical sample in a liquid droplet. The apparatus comprises a processing compartment, which is defined by a reservoir and an immobilization member. The processing compartment is further adapted to accommodate a medium, which is immiscible with the liquid droplet, and of a lower surface energy than the liquid of the liquid droplet. The reservoir is defined by a circumferential wall and a base. The immobilization member is arranged within the reservoir and comprises a surface that is patterned in such a way that it comprises at least one predefined immobilization area. The predefined immobilization area within the patterned surface is of a higher surface energy than the medium. The liquid droplet is disposed onto the predefined immobilization area, whereby the liquid droplet is immobilized thereon via hydrophilic-hydrophilic or hydrophobic-hydrophobic interactions.
摘要:
An apparatus comprises a plurality of bushings arranged and held together in an array; and a plurality of pins residing in the plurality of bushings, wherein the plurality of pins are for transferring samples. Manufacturing tolerances for inside diameters of the bushings and outside diameters of the pins substantially match to allowing the pins to slide freely within the bushings. The plurality of bushings can reside in one or more plates, each of which having plurality of holes, with the plurality of bushings being held together in the array.
摘要:
The systems and methods disclosed herein permit automated preparation of biological specimens for examination. The disclosed systems and methods provide fast, efficient, and highly uniform specimen processing using minimal quantities of fluids. The methods include at least a fixing phase for fixing a biological specimen to a substrate such as a microscope slide, a staining phase for staining the specimen, and a rinsing phase for rinsing the specimen. One or more of the fixing, staining, and rinsing phases include one or more agitation cycles for distributing reagents evenly and uniformly across the specimen. The systems can be implemented as a standalone device or as a component in a larger system for preparing and examining biological specimens.

Aspects of the invention provide systems and methods for high-throughput screening of fluidic samples. In some embodiments, two chromatography columns are utilized in series. The first chromatography column can have a high affinity for phosphorylated compounds while the second chromatography column has a high affinity for one or more analytes of interest.
摘要:
A slotted pin tool, a delivery system containing the pin tool, a substrate for use in the system and methods using the pin tool and system are provided. The slotted pin tool contains a plurality of pins having slotted ends designed to fit around each loci of material deposited on a surface, such as a microarray, without contacting any of the deposited material. Sample is delivered by contacting the pin tool with the surface; the amount delivered is proportional to the velocity of the pin tool as it contacts the surface or the velocity of the liquid when movement of the pin is halted.
摘要:
A multi-chambered deposition pin wash station is provided. The wash station includes a lower chamber and an upper drain basin connected by a plurality of wash tubes. Cleaning fluid is provided to the lower chamber and passes through the cleaning tubes into the upper drain basin. The cleaning tubes are adapted to clean a single deposition pin with a single tube per wash cycle.
