Binding assay system and method of making and using same
First Claim
1. For use in a system for the diagnostic analysis of a liquid specimen through binding assays, an apparatus comprising:
- a rigid body having an elongated well therein for receiving a liquid specimen;
a plurality of elongated strips oriented in spaced relationship to each other across the elongated well and generally transverse to its longitudinal axis and disposed for contacting the liquid specimen, each strip being coated with a binding assay component such that reactive components in the liquid specimen will be bound thereto; and
a cover plate connected to the rigid body and enclosing the elongated well.

Abstract
Method and apparatus for use in the diagnostic analysis of a liquid specimen through binding assays. The apparatus includes a rigid body having an elongated, shallow well formed in it, with a plurality of elongated strips, preferably in the form of cotton threads, stretched across the well in spaced relationship and generally perpendicular to the well'"'"'s longitudinal axis. Each thread is coated with a separate binding conjugate such as an antigen or allergen. A cover plate that includes a thin plastic layer and an overlaying thin metallic layer covers the well to form an enclosed chamber having a specific volume. The metallic layer includes a separate elongated aperture in alignment with each coated thread. A liquid specimen is introduced into the chamber through one of two ports, for incubation with the coated threads, after which the specimen is removed and the reaction that occurred on each thread is determined.

12. Apparatus for use in a system for the allergy screening of a liquid specimen through binding assays, the apparatus comprising:
-
a rigid plastic body having an elongated, shallow well formed therein, and a substantially flat land surrounding the well; a plurality of cotton threads stretched tautly across the elongated well from the land on its opposite sides, the threads being oriented in spaced parallel relationship substantially perpendicular to the longitudinal axis of the elongated well and disposed for contacting the liquid specimen, each thread coated with a different allergen or group of allergens for binding corresponding antibodies in the liquid specimen; a substantially flat cover plate secured to the land of the rigid body, to enclose the elongated well, the cover plate including a thin, transparent plastic sheet overlaying to the land of the rigid body, and a thin metallic sheet overlaying the plastic sheet and having a plurality of elongated apertures aligned with each of the plurality of cotton threads; and means defining a port at each end of the elongated elongated well, to facilitate insertion and removal of a liquid specimen in the well, for contact with the plurality of cotton threads.

13. A method for the diagnostic analysis of a liquid specimen through binding assays, comprising the steps of:
-
coating each of a plurality of elongated strips with a binding assay component such that reactive components in the liquid specimen will be bound thereto; positioning the plurality of elongated strips in a predetermined spaced relationship to each other in a chamber of prescribed volume formed within a rigid body; placing a liquid specimen in the chamber and incubating the specimen in contact with the coated strips; removing the liquid sample from the chamber; and measuring the reaction occurring between the liquid specimen and each of the coated strips. - View Dependent Claims (14, 15, 16, 17)
