  • Method for treatment of reeds
    Patent number: 5379673
    Abstract: A composition and method for treating reeds to prolong their useful life containing an oxidizing agent, such as hydrogen peroxide, a humectant, such as glycerol and water. Reeds are preferably routinely treated with the composition after each use or on a weekly basis by submerging the reeds in the composition at least up to the end of their playing surfaces until the bubbling action ceases. They are then removed from the solution, wiped off and stored.

  • Method for corrective calibration of a flow cytometry using a mixture of fluorescent microbeads and cells
    Patent number: 5084394

The use of calibrated biological cells permits correction for factors related to the instrument and calibration microbeads so long as the excitation and emission spectra of the calibration microbeads, the calibration cells and the cell samples are all the same, respectively.
