Latest Patents
One of her latest patents is the "Initial rate photometric method for immunoassay." This method is useful for detecting and quantifying analytes in various physiological fluids. It involves combining an undiluted sample of analyte-containing physiological fluid, such as serum, with an excess of an anti-analyte antibody. The method measures a substantially constant initial rate of increase in the turbidity of the liquid medium, which is due to the resulting immunoprecipitation reaction. This measurement is compared to a calibration curve prepared from known analyte concentrations to detect and quantify the analyte. The method allows for rapid detection and quantification of numerous analytes, including haptens, drugs, and proteins.
Another significant patent is the "Method of heterogenous purification using a bidentate conjugate." This novel method removes a macromolecule from a liquid by allowing it to undergo a specific binding affinity reaction with a bidentate conjugate. The process involves immobilizing the bidentate conjugate on a solid phase, contacting it with the liquid containing the macromolecule, and then separating the immobilized bidentate conjugate from the liquid. This results in either a purified macromolecule or a purified liquid.
