摘要:
In a first aspect, the invention relates to the use of a UV-polymerizable composition as an embedding medium for biological samples. The UV-polymerizable composition is a composition with a refractive index ranging from n = 1.45 to n = 1.6 after a polymerization process. In another aspect, the invention relates to a method for producing embedded biological samples using said UV-polymerizable composition and to the embedded biological samples themselves. The biological samples can be used in a wide variety of areas, such as diagnostics among others, and are suitable in particular for RNA-based diagnostics.

Provided is a block storage device including: a magazine (2) which accommodates embedding blocks (B) to be inserted into or removed from the magazine in a state where the embedding blocks held in a cassette (K) to which ID data is attached are arranged vertically in one row; a magazine holding portion (3) which detachably holds each of the magazines; and a reading portion (20) which reads the ID data. The magazine holding portion includes a rotary body (50) which is rotatable around a rotation axis O, a holding mechanism (51) which is multiply provided on a circumferential wall portion (56a) in the rotary body and detachably holds the magazines individually, and a rotation drive portion (52) which positions one of the magazines at a block extraction position (P2) facing the reading portion by rotating the rotary body, and the magazine positioned at the block extraction position and the reading portion are movable relative to each other along the vertical direction.
摘要:
The present invention provides a method for preparing a sample for microscopy, said method comprising the steps of contacting said sample with a first polymerizable resin under conditions and for a time sufficient for penetration of said first polymerizable resin into the sample, removing excessive first polymerizable resin from the surface of the sample, contacting the so-prepared sample containing said first polymerizable resin with a second polymerizable resin preparation, said second polymerizable resin preparation comprising a high concentration of electrically conductive particles, and subjecting the so-prepared sample to the curing temperature of the polymerizable resins, wherein the curing temperature of said second polymerizable resin preparation is substantially the same as the curing temperature of the first polymerizable resin.

The present invention relates to a composition for aggregating biological sample used for manufacturing paraffin block for microscopic observation of biological sample, a method for preparing paraffin block using the same, and a method for microscopic observation of biological sample using the paraffin block, and particularly to a composition for aggregating biological sample including the first composite containing at least one water-soluble polymer selected from the group comprising polyvinyl alcohol, polyethylene oxide, polyacrylamide, polyvinylpyrrolidon, polyacrylic acid, polyethyleneimine, polyamines, polyamideamine, and polydiallyl dimethylammonium chloride and distilled water; and the second composite containing at least one organic solvent selected from the group comprising alcohol, xylene, and acetone and at least one medical adhesive selected from the group comprising cyanoacrylate, fibrin glue, protein glue, polyurethane, and sealant containing PEG (polyethylene glycol), a method for preparing paraffin block using the same, and a method for microscopic observation of biological sample using the prepared paraffin block. According to the present invention, because preparing the sample complex is done in a centrifuge tube in preparing paraffin block using extremely small amount of fluid sample tissue or cells, it is possible to minimize loss or damage of sample, reduce background staining, facilitate the preparing process of paraffin block, save time and cost required for preparing paraffin block, and improve the quality of slide obtained from micro-section of the paraffin block.
