             Biological Data
  | Application notes |   The biological activity was determined using a chemotaxis bioassay using human neutrophils at a concentration range of 10-100 ng/ml  | 
  Solubility & Handling
  | Solubility overview |   To make a stock solution, reconstitute in sterile 18MΩcm water at a concentration > 100μg/ml, which can then be diluted to make a working solution  | 
   | Handling |   
- Solutions should be made in sterile deionized water (not less than 100 µg/ml). This solution can then be further diluted with other aqueous solutions.
 
- Following reconstitution, solutions may be stored at 4°C and are useable for around 2-7 days and for future use store at -18°C.
 
- Freeze-thaw cycles should be prevented.
