Abstract:
A contact lens storage chamber (10) has a lens retaining member (15) disposed therein with baskets (20, 21) for containing the lenses disposed in a vertically juxtaposed manner. The lens retaining member has a stopper portion (16) which is located in an opening at the top of the chamber and is retained in place by a loose tongue-in-groove structure (17, 18) which facilitates the escape of vapors from the chamber during a lens cleaning and disinfecting procedure.

Abstract:
A reusable seal assembly (12) for sealing a plurality of containers (15) arranged in close proximity to one another. The seal assembly (12) includes a subassembly comprising a pliable sealing component (21) having a plurality of spaced protrusions (26) positioned to seal openings (19) of the containers (15), and a substantially rigid supporting component (22) for supporting the sealing component (21) and for effecting the substantially simultaneous sealing of the openings (19) of the containers (15) by the plurality of protrusions (26) when the subassembly is mounted on the containers (15), and the substantially simultaneous withdrawal of the plurality of protrusions (26) from the openings (19) when the subassembly is removed from the containers (15). The seal assembly (12) also includes a shipping component (23) adapted to be mounted to the subassembly to strengthen the seal between the protrusions (26) and the containers (15) for use particularly during shipping of the containers (15) when rough treatment may be expected. The seal assembly (12) of the present invention is particularly designed to seal multi-vial, multi-dose reagent packs for clinical analyzer apparatus, and also includes a surface (42) thereon for carrying indicia (43) to identify a seal assembly (12) with its particular reagent pack.

The apparatus also includes a mechanism (36) for aspirating and dispensing liquids which includes a liquid level detecting mechanism (70, 72, 74, 76, 78, 80, 82, 84). The device further includes a microprocessor and logic (44) for controlling the apparatus operation and analyzing the information received from the image forming device (42) to generate a visual indication of assay results.
Abstract:
This invention presents novel assay methods employing a capture reagent, involving a first binding member typically conjugated to a polymeric anion substance, and a solid phase material containing a reaction site comprising a polymeric cation substance having a nitrogen content of at least about two percent. In one embodiment a test sample suspected of containing the analyte of interest may be contacted with the capture reagent to form a charged capture reagent/analyte complex. The complex is then contacted to the oppositely charged solid phase to attract, attach, and immobilize the capture reagent/analyte complex. The use of a polycationic substance, having a nitrogen content of at least about two percent (excluding the counter ions), to prepare a suitably charged solid phase provides a solid phase that can be subjected to a greater extent of manipulation, such as multiple washes, without losing the capability to attract and retain the capture reagent.
Abstract:
The present invention includes novel assays and reagents using a capture reagent, involving a specific binding member attached to a polymeric anionic substance, and a solid phase material containing a capture or reaction zone including a polymeric cationic substance. A test sample suspected of containing the analyte of interest may be contacted with the capture reagent to form a charged capture reagent/analyte complex. The complex is then contacted to the oppositely charged solid phase to attract, attach, and immobilize the capture reagent/analyte complex. With an appropriate indicator reagent, sandwich, competitive and indirect assays can be performed. Preferably, the indicator reagent includes a nonspecific binding blocker to reduce the nonspecific binding between the indicator reagent and the solid phase, without interfering with the reaction between the capture reagent and the solid phase. Suitable nonspecific binding blockers include unbound or free polyanionic materials such as dextran sulfate, heparin, carboxymethyl dextran, carboxymethyl cellulose, pentosan polysulfate, inositol hexasulfate or beta -cyclodextrin sulfate.
