  • System for identification of cells by electrophoresis
    Patent number: 4707237
    Abstract: Cells are identified electrophoretically through isoenzyme analysis. The use of standard and control cells allows semi-skilled workers to achieve reproducible results. A coding sequence is assigned to the cels to be identified using a grid to interpret the electrophoretic separations observed on a series of electrophoretic films, each film being developed for a particular isoenzyme. Comparison of the coding sequence with a compendium of coding sequences for known cells identifies the cells to be identified.
    Type: Grant
    Filed: September 9, 1982
    Date of Patent: November 17, 1987
    Assignee: Ciba Corning Diagnostics Corp.
    Inventors: Cyrus A. Lepp, James J. Mussatto, James M. Ziegenmeyer
  • Determining creatine kinase isoenzmes via immobilized antibody-isoenzyme complexes
    Patent number: 4260678
    Abstract: Creatine kinase isoenzymes in a liquid sample are determined by means of immobilized antibody-isoenzyme complexes in which measureable isoenzyme activity is retained.

  • Alkaline agarosse gel electrophoresis of hemoglobins
    Patent number: 4209372
    Abstract: The common hemoglobin variants A, A.sub.2, F, S, and C are discretely separated by alkaline agarose gel electrophoresis employing (1) an agarose gel having a wet thickness of from about 0.1 to about 0.5 mm., (2) a gel buffer comprising tris(hydroxymethyl)aminomethane, ethylenediaminetetraacetic acid, and boric acid, and having an ionic strength of from about 0.065 to about 0.1 and a pH of from about 8.7 to about 9.1, (3) a well buffer comprising diethylbarbiturate and ethylenediaminetetraacetate and having an ionic strength of from about 0.01 to about 0.11 and a pH of from about 8.0 to about 9.5, and (4) a potential of from about 150 to about 300 volts.

  • Acidic agar gel electrochromatography of hemoglobins
    Patent number: 4209373
    Abstract: The common hemoglobin variants A, A.sub.2, F, S, and C are discretely separated by electrochromatography under acidic conditions on an agar gel which utilizes an agar gel having a wet thickness of from about 0.1 to about 0.5 mm. and a potential of from about 60 to about 110 volts. The gel buffer is a citrate buffer having a citrate concentration of from about 0.04 to about 0.065 M and a pH of from about 6.0 to about 6.5. The well buffer is a citrate buffer having a citrate concentration of from about 0.055 to about 0.065 M and a pH of from about 6.0 to about 6.5.
