Fluoroimmunoassaying

View page
US Patent:
45769125, Mar 18, 1986
Filed:
Feb 28, 1983
Appl. No.:
6/470516
Inventors:
Sidney Yaverbaum - East Windsor NJ
Jacob Kusnetz - New City NY
Assignee:
Technicon Instruments Corporation - Tarrytown NY
International Classification:
G01N 5300
G01N 33553
G01N 33544
G01N 33542
US Classification:
435 7
Abstract:
A method of composition is featured for performing a fluoroimmunoassay of a biological fluid sample for an immunological reactant. A conjugate of a carrier labelled with fluorophores and coupled to an immunological reactant is mixed with the sample and a known quantity of binding agent. After equilibrium is accomplished, the bound and unbound portions are separated. The carrier in a selected portion is chemically treated to liberate the fluorophores. The fluorescent level is then measured and compared with a standard.

Apparatus And Method For Detecting Chemiluminescent Light

US Patent:
57143889, Feb 3, 1998
Filed:
Aug 14, 1996
Appl. No.:
8/696649
Inventors:
Jacob Kusnetz - New City NY
Assignee:
Bayer Corporation - Tarrytown NY
International Classification:
G01N 2176
US Classification:
436172
Abstract:
The apparatus for detecting chemiluminescent light is a component of a luminometer that can be incorporated in a sample analysis system. Such apparatus, also referred to as a fiber optic read-head, includes a fiber optic cable having a light-transmission end that connects to a photon counter of the luminometer. An opposite end portion of the fiber optic cable is divided into a plurality of fiber optic ribbons. Each of the fiber optic ribbons has a light-receiving end. The ribbons are radially arranged such that the light-receiving ends define a cylindrical passageway for accommodation of a sample analysis tube or cuvette. The fiber optic ribbons are maintained in their desired position by a core. The core is housed in an opaque housing that prevents light from coming in or straying out. Thus, any chemiluminescent light emitted from a tube within the core is collected by the light receiving ends of the fiber optic ribbon and transmitted to the light-transmitting end of the fiber optic cable for conversion into electronic data.

Apparatus And Method For Determining The Concentration In A Sample

US Patent:
41992601, Apr 22, 1980
Filed:
Aug 21, 1978
Appl. No.:
5/935411
Inventors:
Jacob Kusnetz - New City NY
Warren Groner - Whitestone NY
Assignee:
Technicon Instruments Corporation - Tarrytown NY
International Classification:
G01N 2148
G01N 3108
US Classification:
356411
Abstract:
Apparatus and method for determining the concentration of a constituent in a sample using chromatographic and optical measuring techniques. A sample containing a constituent to be analyzed is fractionated by a chromatographic column. A light beam is passed through the constituent fraction in the column, and the light absorbance (or transmittance) is measured. The fluid carrier (or solvent) eluting through the column will generally increase the transmissivity of the light passing through the column due to a difference between the indices of refraction of the carrier fluid and the chromatographic packing material. Such increased transmissivity will generally offset any decrease in the transmittance due to trace amounts of the constituent in the sample. The optical measurement is compensated to nullify such increased transmissivity, so as to allow measurement of such trace amounts of constituents.
