    • The end of a cable or other elongated object is held in a plastic retainer molded of one piece. The retainer has a base with a pocket for holding the object, upstanding supports alongside the pocket and a retaining element mounted between adjacent supports at each side of the pocket. The retaining element defines a snap element and resilient hinges, either flexible webs or torsion arms, which couple each end of the snap element to a support for rotation of the snap element about an axis. The axes are above the pocket and the snap element extends down to hold the object in the pocket. Optional over-center action provides a locking function. Release tabs on the retaining element extending above the axis permits release of the cable by pinching the tabs together. Grooves or ridges on the cable end engage the retainer for axial retention and permit axial adjustment as well. A receiving opening in the retainer is shaped to guide cable end insertion.
    • 电缆或其他细长物体的端部被保持在由一片成型的塑料保持器中。 保持器具有底座,其具有用于保持物体的口袋,沿着口袋的直立支撑件以及安装在口袋每侧的相邻支架之间的保持元件。 保持元件限定卡扣元件和弹性铰链,柔性腹板或扭转臂,其将卡扣元件的每个端部联接到支撑件,以使卡扣元件围绕轴线旋转。 轴位于口袋上方,卡扣元件向下延伸以将物体保持在口袋中。 可选的超中心动作提供锁定功能。 在轴上延伸的保持元件上的释放卡舌允许通过将突片夹在一起而释放电缆。 电缆端部上的槽或脊与保持器接合,用于轴向保持,并允许轴向调节。 保持器中的接收开口成形为引导电缆端插入。

    • The present invention is directed to replicable expression vectors for producing fusion proteins which are secreted in membraneous particles budded from the cell membrane. In particular these vectors express a hybrid gene product composed of a modified retrovirus gag gene fused to a heterologous gene, or any part thereof, wherein the gag gene modification is sufficient to enable a cell to produce the hybrid gene product in a membraneous particle by budding from the cell membrane into the culture medium or extracellular space, a process known as retrovirus-mediated secretion. The minimum gag sequences needed to obtain particle formation are described. The invention also provides hosts containing the expression vectors, and the fusion proteins produced by the vectors. Further the invention provides the membraneous particles produced by retrovirus-mediated secretion and uses of these particles for protein purification and in therapeutics.
    • 本发明涉及用于产生分泌于从细胞膜发芽的膜状颗粒中的融合蛋白的可复制的表达载体。 特别地,这些载体表达由与异源基因或其任何部分融合的修饰的逆转录病毒gag基因组成的杂合基因产物,其中所述gag基因修饰足以使细胞能够通过出芽在膜状颗粒中产生杂交基因产物 从细胞膜进入培养基或细胞外空间,称为逆转录病毒介导的分泌过程。 描述了获得颗粒形成所需的最小gag序列。 本发明还提供含有表达载体的宿主和载体产生的融合蛋白。 此外,本发明提供了由逆转录病毒介导的分泌产生的膜状颗粒和这些颗粒用于蛋白质纯化和治疗的用途。
