The activity is determined by the ability to chemoattract purified human neutrophils and is detectable starting at 10 ng/mL.
Storage Buffer:
No additive
Storage Instruction:
Store at -20°C on dry atmosphere. After reconstitution with sterilized water, store at -20°C or lower. Aliquot to avoid repeated freezing and thawing.
Note:
Result of activity analysis
Triplicate samples of primary human neutrophils from three donors were allowed to migrate to human CXCL2 (10, 100 and 1000 ng/mL). After 30 minutes, cells that migrated were counted using a luminescent substrate and displayed on the bar graph above.
