  • METHOD OF EVALUATING THE INTEGRITY OF THE PLASMA MEMBRANE OF CELLS BY DETECTING GLYCANS FOUND ONLY INTRACELLULARLY
    Publication number: 20110143373
    Abstract: The invention describes novel reagents that can be applied for analysis of the quality of human cells. The method evaluates the integrity of the plasma membrane of the cells by detecting novel glyco structures found only intracellularly. The method can be applied, for example, to demonstrate exposure of therapeutic cell preparation to potentially harmful conditions. It can also be used as a quality control tool in methods in which intact cell membrane is essential and it can be applied in separation of damaged cells from non- damaged.

  • NOVEL CARBOHYDRATE PROFILE COMPOSITIONS FROM HUMAN CELLS AND METHODS FOR ANALYSIS AND MODIFICATION THEREOF
    Publication number: 20100145032
    Abstract: The invention describes reagents and methods for specific binders to glycan structures of stem cells. Furthermore the invention is directed to screening of additional binding reagents against specific glycan epitopes on the surfaces of the stem cells. The preferred binders of the glycans structures includes proteins such as enzymes, lectins and antibodies.
