Abstract

Correlation between cell cycle of the synchronous yeast culture and ESR signal intensity at g 2.2 and 77 K was studied. It was shown that the maximal intensity of ESR signal was reached 10-15 min before the beginning of intensive cell division. The ESR signal with g 2.2 (77 K) is caused by the spin-glass like structure. The "freezing" temperature of these spin-glasses was measured.

摘要

研究了同步酵母培养物的细胞周期与77K下g 2.2处的电子自旋共振(ESR)信号强度之间的相关性。结果表明,ESR信号的最大强度在细胞开始密集分裂前10 - 15分钟达到。g 2.2(77K)处的ESR信号是由类自旋玻璃结构引起的。测量了这些自旋玻璃的“冻结”温度。
