The activity is determined by a viral challenge assay using EMC virus on L929 cells, is 1.1-1.3 x 107 Units/mg. The expected ED50 for this effect is 0.04-0.09 ng/mL.
Storage Buffer:
Lyophilized with 0.5X PBS, pH 7.2.
Storage Instruction:
Store at -20°C on dry atmosphere. After reconstitution with sterilized water, store at -20°C. Aliquot to avoid repeated freezing and thawing.
Note:
Result of activity analysis
The specific activity, as determined in a viral challenge assay using EMC virus on L929 cells, is 1.15-2.3 x 107 Units/mg. The corresponding ED50 is 0.086-0.043 ng/mL.
