  • Method for obtaining informative cells
    Patent number: 5627029
    Abstract: The subject invention relates to a method for processing a liquid sample of biological material by: a) transferring a liquid sample containing both uncultured informative cells and non-informative cells onto a substrate wherein the surface tension of the liquid sample is sufficient to maintain the liquid sample beaded on the surface of the substrate; b) incubating the beaded liquid sample on the surface of the substrate for a period of time appropriate for the selective settling of the informative cells onto the surface of the substrate; and c) breaking the surface tension of the liquid portion of the sample wherein the liquid portion of the sample is removed along with the non-informative cells and wherein the informative cells remain on the surface of the substrate.A kit for performing the method is also provided.
