    • Growth chambers for anchorage-independent cell growth therein are formed of a gel matrix having a surface disallowing anchorage-dependent cell growth over the full interior thereof. In a preferred form the chambers have a generally cylidnrical wall and an integral convex bottom wall forming an annular volume at the foot of the cylindrical wall which is substantially lower than the central portion to concentrate such anchorage-indpendent cells. The gel matrix is sufficiently permeable to permit passage of cell-growth nutrients and waste product solutes through said wall when the chambers are filled below the open end and submerged in a growth medium. Preferably the gel matrix is formed of 1% to 5% cross-linked polyacrylamide and from 99% to 95% water.In a preferred method of using the growth chambers, undifferentiated tumor cells and normal cells, including fibroblasts, are cultured together. Anchorage-independent tumor cells proliferate while anchorage-dependent cells are unable to grow without attachment. The method is useful for evaluating in vitro therapeutic agents to control tumor growth, normal cell growth or microspheres and generation of immunoglobulins from lymphocyte cells.
    • 用于与其无关的细胞生长的生长室由具有在其整个内部不允许锚定依赖性细胞生长的表面的凝胶基质形成。 在优选形式中,室具有大致圆形的壁和整体的凸底壁,其在圆柱形壁的底部形成基本上低于中心部分的环形体积,以集中这种固定型静电池。 凝胶基质足够透气,允许细胞生长营养物质和废产物溶质通过所述壁,当室被填充在开口端下方并浸没在生长培养基中时。 优选地,凝胶基质由1%至5%的交联聚丙烯酰胺和99%至95%的水形成。 在使用生长室的优选方法中,将未分化的肿瘤细胞和包括成纤维细胞的正常细胞一起培养。 不依赖锚定依赖的细胞不能生长而不依赖于锚定的肿瘤细胞增殖。 该方法可用于评估体外治疗剂以控制肿瘤生长,正常细胞生长或微球体以及从淋巴细胞细胞产生免疫球蛋白。

    • Exemplary disclosed embodiments may comprise, for example, providing a sample potentially comprising a native molecule and/or a truncated molecule. The native molecule comprises at least first and second regions recognized by first and second specific binding moieties, and the truncated molecule includes only one of the first and second regions. A composition comprising first and second specific binding moieties is applied to the sample in a manner effective to form first and second specific binding pairs with the first and second regions. For example, if the molecule is a protein, such as HER2, the protein may have a first epitope and a second epitope. Once a specific binding pair is formed, the pair must be visualized. Certain disclosed embodiments comprise a direct detection method whereby primary antibodies are coupled to signal generating moieties. Alternatively, signal amplification techniques can be used to visualize a specific binding pair.
    • 示例性的公开实施例可以包括例如提供潜在地包含天然分子和/或截短分子的样品。 天然分子包含由第一和第二特异性结合部分识别的至少第一和第二区域,并且截短分子仅包括第一和第二区域中的一个。 将包含第一和第二特异性结合部分的组合物以有效形成与第一和第二区域的第一和第二特异性结合对的方式施用于样品。 例如,如果分子是诸如HER2的蛋白质,则蛋白质可以具有第一表位和第二表位。 一旦形成特定的结合对,该对必须可视化。 某些公开的实施方案包括直接检测方法,其中一抗被偶联到信号产生部分。 或者,可以使用信号放大技术来可视化特异性结合对。
