| Summary | 
 | 
| Source | 
 | 
| Molecular Weight | 
Approximately 19.2 kDa, a single non-glycosylated polypeptide chain containing 172 amino acids. | 
| Biological Activity | 
Fully biologically active when compared to standard. The ED50 determined by its ability to induce TNF-alpha production by human PBMCs. | 
| Appearance | 
Sterile Filtered White lyophilized (freeze-dried) powder. | 
| Formulation | 
Lyophilized from a 0.2 um filtered concentrated solution in PBS, pH 7.4. | 
| Endotoxin | 
Less than 0.1 EU/ug of rHusCD23 as determined by LAL method. | 
| Reconstitution | 
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/ml. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions. | 
| Stability and Storage | 
Use a manual defrost freezer and avoid repeated freeze-thaw cycles.- 12 months from date of receipt, -20 to -70 °C as supplied.- 1 month, 2 to 8 °C under sterile conditions after reconstitution.- 3 months, -20 to -70 °C under sterile conditions after reconstitution. |
