  • Process, device and reagent for cell separation
    Patent number: 7316897
    Abstract: A cell separation process for the isolation of pathogenic cells in a small concentration in a biological fluid specimen, including treating the biological specimen to modify in a differential manner selected rare cells and other cells and causing differential migration of cells that reacted during treatment versus cells that did not react during treatment.
    Type: Grant
    Filed: February 22, 2001
    Date of Patent: January 8, 2008

  • Procedure for identifying the number of particles that are weakly luminescent
    Patent number: 5828716
    Abstract: The present invention relates to a procedure for counting faintly luminescent particles, and relates specifically to a procedure for counting cells and microorganisms marked with a colored or fluorescent stain or marker that selectively marks the microorganisms and cells to be counted, characterized by the fact that the said procedure is implemented with the aid of a photon-accumulator camera and includes the acquisition of at least one low-resolution image I, the threshold processing of the said low-resolution image in order to obtain at least one digital image Ib, at least one dimensional filtration stage, and the counting of the number N of objects belonging to a given class of sizes in the digital image Ib.
