<p>PURPOSE:To obtain an inexpensive live cell preservative, containing kestose as an active ingredient, having excellent preserving effects and exhibiting effects on not only freezing preservation but also preservation at a low temperature so as not to freeze the live cells. CONSTITUTION:A live cell preservative containing 1-kestose as an active ingredient, preferably at 0.1-20% (wt./vol.) concentration. The 1-kestose is obtained by reacting a fructosyltransferase produced by Scopulariopsis.brevicaulis with, e.g. sucrose.</p> |
