LYOPHILIZATION OF THYLAKOIDS FOR IMPROVED HANDLING IN A BIOASSAY

摘要

The thylakoid bioassay is used to determine the effect of herbicides in water. To avoid isolation for each bioassay, lyophilization of thylakoids for continuous, reproducible supply as bioassay material is descibed. This technique maintains the pho-tosynthetic activity after lyophilization at 82 ± 9% (n = 5) of its original level.
