    Abstract: A readily disposable ion selective electrode assembly, free of onboard reagents, for use in analyzers has a reference element and plural sensor elements linearly positioned in parallel on a substrate. An elastomeric flow channel member containing two parallel grooves creates flow channels on the substrate above the elements. The substrate holds the elastomer in compression and is retained by snaps injection molded into a housing. Electrical contacts and leakfree fluidic connections are provided by spring loaded connectors through the housing. Reference and sample fluids are drawn through the respective flow channels and come together to form a liquid junction downstream from the sensor elements. Bubbles, that might otherwise cause erroneous results, are detected.

    Abstract: The invention is drawn to a diagnostic assay for lactate dehydrogenase isoenzyme LD1 in a sample containing lactate dehydrogenase isoenzymes LD1-LD5. The disclosed assay involves the following steps: (A) adding a high molecular weight polyol, preferably polyethylene glycol having a molecular weight of 8000, to the sample to stabilize isoenzyme LD1 but not isoenzymes LD2-LD5; (B) adding an ionic amphiphile to the sample to selectively inactivate isoenzymes LD2-LD5; (C) adding sodium lactate and NAD to the sample; (D) determining LD1 by measuring a change in absorbance of the sample at 340 mm.
