    • Systems and methods for automated laser microdissection are disclosed. In one variation, targeted biological material is manually or automatically selected and a transfer film is placed in juxtaposition to the location of an interior of a cut path. In another variation, a sample of biological material is mounted onto a polymer membrane which is then placed onto a substrate. Targeted biological material is manually or automatically selected and a transfer film is placed in juxtaposition with the targeted biological material on the side of the biological material. In yet another variation, a sample of biological material is mounted onto a polymer membrane which is then inverted onto a substrate. Targeted biological material is manually or automatically selected and a transfer film is placed in juxtaposition with the targeted biological material on the side of the polymer membrane. Then, an UV laser cuts along a cut path around the targeted portions of biological material in a closed cut path or a substantially closed cut path defining an interior and an exterior portion of the tissue sample. In a substantially closed cut path, bridges are left spanning the interior of the cut path and the exterior of the cut path. An IR laser activates at least a portion of the transfer film such that the transfer film in the vicinity of targeted portion adheres to the biological material interior to the cut path. The transfer film is then removed separating the targeted portions of biological material which are adhered to the transfer film from the remaining portion of the tissue sample.

    • The present disclosure concerns methods, systems, and devices for analyzing a biological material, such as a cellular or other specimen. In one disclosed example, the method selectively transfers biomolecules from a target region of interest in a biological sample (such as a tissue section). The transfer may occur, for example, by selectively focally altering a characteristic of a transfer layer adjacent the target region, such that the biomolecules can move through the altered area of the transfer layer. In particular examples, the transfer layer is altered by focally increasing a permeability of the transfer layer, for example by removing a focal portion of the transfer layer, and transporting the biomolecules through the altered region of the transfer layer, to microdissect the biomolecules of interest from the biological sample. In yet other embodiments, the microdissected biomolecules can be applied to an analysis substrate containing an identification molecule, such as a nucleic acid array, layered expression scan, or wells containing antibodies. Transfer microdissection allows biomolecules from regions of interest in the biological specimen to be selectively analyzed. For example, nests of highly atypical or metastatic cells in a tumor section can be analyzed for differential expression of certain proteins.

    • 本公开涉及用于分析生物材料(例如细胞或其它样品)的方法,系统和装置。 在一个公开的实施例中,该方法选择性地将生物分子从目标感兴趣区域转移到生物样品(例如组织切片)中。 转移可以例如通过选择性地改变邻近目标区域的转移层的特性,使得生物分子可以移动通过转移层的改变的区域而发生。 在具体实例中,转移层通过聚焦增加转移层的渗透性而被改变,例如通过去除转移层的焦点部分,以及将生物分子传输通过转移层的改变区域,以显微分解感兴趣的生物分子 来自生物样品。 在其他实施方案中,显微切割的生物分子可以应用于含有鉴定分子,如核酸阵列,分层表达扫描或含有抗体的孔的分析底物。 转移显微切割允许选择性分析来自生物样本中感兴趣区域的生物分子。 例如,可以分析肿瘤部分中的非典型或转移性细胞的巢,以鉴别某些蛋白质的差异表达。

    • A low temperature melt film such as EVA is prepared for laser capture microdissection by having a thin specimen non-adhering coating in the range of 0.1 % to 10 % of the total film thickness placed on the sample exposed side of the film. When the film is brought into contact with the specimen, the specimen non-adhering coating prevents non-specific transfer due to sticky adherence of portions of the sample. At the same time, the non-adhering coating on the low temperature melt film surface can stabilize and protect the low temperature melt film against variations in performance due to ambient humidity and temperature variation. Upon appropriate heating for laser capture microdissection, the barrier of the thin coating allows conventional film melting with otherwise uninhibited adhesion of selected cell areas to the film. Coatings on the low temperature melt film (EVA) surface in selected locations is made by applying film-forming material from a volatile solvent-based solution, followed by evaporation of the solvent. The coating solution can be applied by spraying, dipping, or adding exact volumes to a surface with a micropipet. Spreading a measured volume of solution over the surfaces can coat flat surfaces. The coating thickness can be controlled by the volume and concentration of coating solids added to a known area.
    • 制备低温熔融膜如EVA,用于激光捕获显微切割,其具有薄膜样品非粘附涂层,该涂层在放置在膜的样品暴露面上的总膜厚度的0.1%至10%的范围内。 当膜与样品接触时,样品不粘附涂层防止由于样品的部分粘附而导致的非特异性转移。 同时,低温熔融薄膜表面上的非粘附涂层可以稳定和保护低温熔融膜,防止由于环境湿度和温度变化而导致的性能变化。 在适当加热用于激光捕获显微切割的情况下,薄涂层的屏障允许常规的膜熔化,否则所选择的细胞区域不受阻碍地粘附到膜上。 在选定位置的低温熔融膜(EVA)表面上的涂层通过从挥发性溶剂基溶液中涂覆成膜材料,随后蒸发溶剂来制备。 涂布溶液可以通过喷涂,浸渍或使用微量捕集器将精确体积添加到表面来施加。 将测量体积的溶液涂抹在表面上可以涂覆平坦的表面。 涂层厚度可以通过添加到已知区域的涂层固体的体积和浓度来控制。
