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.

Abstract: Provided is a pest control composition containing an iminopyridine derivative represented by the following Formula (I) and at least one of other pest control agents: [in the formula (I), Ar represents a 5- to 6-membered heterocycle which may be substituted, A represents a heterocycle having a 5- to 10-membered unsaturated bond including one or more nitrogen atoms, and has an imino group substituted with an R group at a position adjacent to the nitrogen atom present on the cycle, Y represents hydrogen, halogen and the like, and R represents any one of groups represented by the following Formulae (a) to (e), (y) or (z)].
