  • recombinant antigens, purification of polyclonal anti- IgG and IgY antibodies and detection
    Patent number: 11753439
    Abstract: The present invention relates to a stationary phase for the purification of polyclonal anti-Giardia IgG and IgY antibodies, as well as a method for purifying polyclonal anti-Giardia IgG and IgY antibodies by affinity chromatography. The invention also relates to the polyclonal anti-Giardia IgG and IgY antibodies purified by affinity chromatography, which specifically bind to the antigenic proteins CWP1, alpha-giardin 7.3 and kinesin 3. In an additional aspect, the invention relates to a method for diagnosing giardiasis by detection of Giardia in a specific sample, and a kit for diagnosing giardiasis in biological and environmental samples.

  • Increased battery capacity utilizing multiple smart batteries
    Patent number: 6262562
    Abstract: A method for allowing a data processing system to use multiple smart batteries substantially simultaneously coupled to the same smart bus, the method including but not limited to detecting at least two smart batteries connected to a smart battery bus; and selectively controlling at least one of the at least two smart batteries via isolation of the smart battery bus clock signal. In one embodiment, circuitry is used to effect the foregoing-described method; the circuitry can be virtually any combination of hardware, software, and/or firmware configured to effect the foregoing-described method depending upon the design choices of the system designer.
