Abstract: Purification of poly-amino acid-tagged recombinant proteins has been improved by the use of a carboxymethylated aspartate ligand complexed with a third-block transition metal having an oxidation state of 2+ and a coordination number of 6. A method for synthesizing the metal ion-CM-Asp complex is also described. Further, the metal ion-CM-Asp complex can be used for screening protein function.

Abstract: An adapter plate transforms a vacuum manifold designed for standard multi-well plates that are commonly used in biochemical laboratories into one that can be used for columns such as chromatographic columns, filtration columns, and the like. The plate contains an array of male-female-type complementary connectors, each connector fitted with a removable plug that seals the connector off when not in use. The plate thus allows the manifold to be used for as few as one column or any number up to the total number of connectors in the plate.

Abstract: A gel filtration plate designed to remove unincorporated dye terminator from a series of reaction mixtures in a nucleic acid sequencing operation is joined to an injection plate designed for insertion into a sequencing apparatus through an adaptor assembly that allows the two plates to be centrifuged together, thereby simultaneously purifying the reaction mixtures and collecting them in the receptacles that will be placed directly in the sequencer. The adaptor avoids the use of an intermediary collection plate and the need to transfer reaction mixtures from each well of the collection plate to each well of the injection plate.

Abstract: There is disclosed a process for manufacturing a padded element. The process comprises the steps of placing a trim cover on a mandrel, the trim cover having a finished outer surface and an inner surface comprised of a thermoformable foam layer; heating the trim cover to a temperature sufficient to shape the thermoformable foam layer; shaping the trim cover to substantially the same shape as the mandrel to produce a shaped trim cover; transferring the shaped trim cover from the mandrel to a lower mold having shape substantially complimentary to the shaped trim cover; placing an upper mold over the lower mold to define a mold cavity; dispensing a liquid foamable polymeric composition in the mold cavity; and expanding the liquid foamable polymeric composition to fill substantially the mold cavity thereby forming the padded element.
