摘要:
An apparatus includes a tissue processing cassette and a biopsy device. The tissue processing cassette is sized to be used in a pathology laboratory for purposes of dehydrating, embedding and sectioning. The tissue processing cassette has at least one distal opening through which tissue samples are received and having a floor with a plurality of openings. The biopsy device is for cutting tissue samples and has a cassette holder configured to translate relative to a proximal end of the biopsy device. The cassette holder is adapted to receive the tissue processing cassette. The cassette holder has a fluid path adapted to be coupled to a vacuum source and be in fluid communication with the interior of the tissue processing cassette through the openings of the floor such that the vacuum from the vacuum source facilitates the transfer of the cut tissue samples into the received tissue processing cassette.

A disposable process chamber (10) for processing biologic material is described, comprising: a containing body (11) for housing the biologic material; holding means (12) for holding the biologic material in the containing body (11) to prevent its movement; closing means (14) associated with liquid seal to the containing body (11); and access means (15) to allow introducing and removing liquids in the disposable process chamber (10), the containing body (11) comprising an upper part (21) configured for housing the closing means (14), and a removable base (16) to allow, at the end of a embedding phase, accessing to the embedded biologic material and perform its cutting, once having removed the removable base (16).

A cell filtration assembly adapted to capture cells from a biological sample during centrifugation includes a filter support member including a sample well and a filter membrane that spans the sample well. In some cases, the filter support member and/or the filter membrane may be adapted to be sectioned. In some cases, a protective element may be disposed over at least a portion of the filter support member in order to protect the filter support member from tissue processing reagents during processing of the cells captured from the biological sample.

This disclosure provides methods for producing size- adjustable tissue-hydrogel hybrids or cell-hydrogel hybrids for imaging cellular and subcellular details and system-scale (e.g., tissue or organism level) intercellular connectivity.
摘要:
The present invention provides methods for processing and analyzing large intact biological samples, including tumor tissue samples. The methods have a variety of uses, including for the diagnosis and monitoring of tumors and tumor metastasis.
摘要:
The invention relates to coded agar bodies for being poured together with specimens into agar blocks or for being processed together with the specimens in a sealed container. The agar bodies may be coded by shape, e.g. stellate, rectangular, cylindrical, color, embedded e.g. cylindrical color codes or figures, such as numbers or letters. Thus, the specimens are marked and individualized independently of the containers at all steps of tissue processing and evaluation.

A histologic tissue sample support device (200) includes a tissue cassette (112), a frame (14), and a lid (118"). The tissue cassette (112) has a recess (112b) including a body (112a) with at least one side wall and a bottom wall (112c) and is formed of material that can be successfully sectioned in a microtome and is resistant to degradation from solvents and chemicals used to fix, process and stain tissue. The tissue cassette (112) is movably coupled to the frame (14). The lid (118") is separably coupled to a peripheral portion (16) of the frame (14). When the lid (118") is separated from the peripheral portion (16), the lid (118") and the tissue cassette (112) are capable of moving from a first position to a second position with respect to the frame (14), and in the second position the bottom wall (112c) and at least a portion of the side wall extend beyond a bottom edge of the frame (14) for sectioning in the microtome.
摘要:
A method of preparing an analytical sample comprising a particulate analyte, for use in microscopy. Disclosed is a method of preparing an analytical sample comprising a particulate analyte, for use in microscopy. A liquid composition is prepared which comprises an embedding medium and the particulate analyte. The liquid composition is consolidated so as to form an analytical sample in which the particulate analyte is immobilized and dispersed within the embedding medium. The resulting analytical sample includes a dispersion of the particulate analyte within an embedding medium, which is representative of the particulate analyte when present in the liquid composition. Optionally, the analytical sample may be stained and/or calibrated using a particulate calibrant. The method is not susceptible to perturbations which might otherwise result in the properties of the analyte in the analytical sample, such as the particle size, particle size distribution, concentration or relative concentration of particles within the particulate analyte differing from those of the analyte in the liquid composition.
摘要:
A system and method for mounting a section onto a substrate, the system comprising: a fluid channel including: a fluid channel inlet that receives the section, processed from a bulk embedded sample by a sample sectioning module positioned proximal the fluid channel inlet, a section-mounting region downstream of the fluid channel inlet, and a fluid channel outlet downstream of the section-mounting region; a reservoir in fluid communication with the fluid channel outlet; and a manifold, fluidly coupled to the reservoir, that delivers fluid from the reservoir to the fluid channel inlet, thereby transmitting fluid flow that drives delivery of the section from the fluid channel inlet toward the section-mounting region.

본 발명은 혈중암세포 진단을 위한 파라핀 블록을 제작함에 있어서 사용되는 혈중 세포 응집용 물질 및 이를 이용한 파라핀 블록의 제작방법에 관한 것으로, 보다 상세하게는 혈액 내에 미량으로 존재하는 혈중암세포(CTC)를 파라핀 블록으로 제작함에 있어서 혈액 시료의 채취를 통해 혈액 내 존재하는 혈중암세포를 검출하는 방법이며, 비침습적이고 간단하기 때문에 암의 재발 및 전이암의 진단 및 예후 예측에 매우 유용하며, 암 발병, 전이 및 재발 기전의 분석을 통해 암 치료의 획기적인 전기를 마련할 수 있다.
