  • Use of non-chelated fluorochromes in rapid test systems
    Patent number: 9274056
    Abstract: The present invention includes an assay method for detecting an analyte in a sample. The assay includes a solid surface such as a nitrocellulose membrane. It also includes providing a sample is applied to the solid surface and detecting the presence or absence of the analyte using a fluorescent label from a lanthanide label. The invention also includes a device for detecting the fluorescence in or on an assay test strip. The device includes a housing, a solid surface and an ultraviolet radiation emitting LED.
    Type: Grant

  • Method for clearing color and debris from or adding adjuvants or reactants to a selected portion of a chromatographic strip alone or in combination with a cell lysing step
    Publication number: 20030186463
    Abstract: In an improved method for clearing a field of observation or treatment of unwanted color or other extraneous material, a chromatographic strip of paper, plastic, glass or like material, with or without simultaneous deposit of adjuvant or reactants on the cleared field, the strip is immersed to a level just barely above the juncture of the zone to be cleared with the preceding zone of the strip in a chase liquid, such as water containing adjuvant if desired. Where red blood cells containing parasitic pathogens such as cholera parasites are to be assayed, a lysing step is performed on the same strip prior to the clearing strip.
