  • Patent number: 10870833
    Abstract: Provided is a method for efficiently and stably separating cells having a high biological activity from a biological tissue, by using a degrading-enzyme composition, which is prepared by adding an enzyme for degrading a major protein of the biological tissue in an amount determined depending on the composition of the major protein to a predetermined amount of a neutral protease and/or a protease derived from Clostridium sp. According to this method, the type and amount of protein-degrading enzyme to be used for isolating cells can be determined from the composition of a major protein of the biological tissue. Thus, cells having a high biological activity can be efficiently separated while reducing the amount of protein-degrading enzyme to be used.
