    摘要: An apparatus for multiple simultaneous synthesis (110), having a number of vials (28), each vial (28) having an upper end (31), a lower end (30), and a barrel (29), the upper end (31) opening into a mouth (32). It also includes a lower frame assembly (180) having a number of holes (101, 103, 105) for receiving the vials (28), and an upper frame assembly (180), which includes inner side-walls (195) and a ceiling portion (190). A gas-tight seal (197) surrounds a plenum (85), the plenum (85) being formed between the ceiling portion (190) of the upper frame assembly (180) and the lower frame assembly (181). The plenum (85) is adjustable in volume by the positioning of the upper frame assembly (180) in variable relation to the lower frame assembly (181), while maintaining the gas-tight seal (197). The volume of the plenum (85) is adjustable to a minimum whereby the mouths (32) of the vials (28) are sealed by the ceiling (190) of the gas-tight seal (197), which is optionally an upper gasket (90). Also disclosed is a plenum enclosure (182) for multiple simultaneous synthesis used in conjunction with vials (28), which includes the upper frame assembly (180) and lower frame assembly (181) and the gastight seal (197), as well as a gasket vial holder (185) to be used in the plenum enclosure (182).

    摘要: An improved multi-well synthesis and filtration apparatus (10) includes a deep-well synthesis block (12) having a plurality of flowthrough wells (24) optionally fitted with filter disks (48) each of the wells (24) being integrally formed in the synthesis block (12), such that any material placed in the wells (24) is in immediate contact with the material of the synthesis block (12), an upper cover (14), a lower cover (16), and a pair of first and second sheet gaskets (18, 20). The first and second sheet gaskets (18, 20) are interposed between the upper and lower covers (14, 16) to seal inlet portions (38) and outlet spouts (40) of the wells (24). The upper and lower covers (14, 16) are independently releasable, and, with the gaskets (18, 20) form a gas tight seal, so that material is retained in the wells (24) when the lower cover (16) is removed, but the upper seal maintained. Apertures (70) in the upper cover (14) provide that the first sheet gasket (18) may be punctured for introduction of materials and/or maintenance of an inert atmosphere. An alternative synthesis block (412) having half the number of wells (424) but configured to be able to use a collection plate (123) of the same array as the first embodiment is also described.

    摘要: The present invention provides a method for purifying a protein complex and the components comprising the complex from a cell, a cell or tissue lysate or a whole organism by employing a combined set of affinity tags of high affinity, specificity and ease of elution. The method involves using a protein or a peptide modified to contain one or more affinity tags separated by one or more specific protease cleavage sites to isolate any interacting proteins or fragments thereof. Specifically exemplified is a method employing a modified bait containing AviTag or GST and a removal tag of His6 hexapeptide positioned proximal to the bait such that any excess bait can be efficiently removed from the purified complex yielding enriched interacting proteins prior to subjecting the complex for further identification of individual components. The identification of the proteins or fragments thereof contained in the protein complex will provide new targets for the identification of new pharmaceuticals and diagnostic tools.

    摘要: A multi-well container (10) is provided in which a greater number of wells may exist than heretofore possible while still maintaining a standard multi-well plate tube array format and footprint. The multi-well container (10) is comprised of a rectangular array of tubes (12) in standard tube format held together by an integrally fashioned plate portion (16). The tubes (12) are subdivided by partitions or septa (14) which extend the height of the tubes (12). Each septum (14) may constitute a single wall or may be comprised of any number of fins (32) which are integral with internal tube surfaces (28). In a symmetrical design with four such fins (32), the fins (32) radiate at angular intervals of 90 degrees from a common central axis (34) with which all four fins (32) are integral. Thus, the septa (14) serve to compartmentalize each tube (12) into symmetrical quadrants of four smaller wells or sub-tubes (30). The preferred embodiment is directed toward usage in conjunction with PCR thermal cyclers, but the multi-well container (10) and the elements as are embodied therein are generally applicable to any laboratory procedure where multiple samples must be treated, evaluated, or stored.
