| Source | E. coli |
| Endotoxins | Endotoxin: Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test. |
| Storage | Lyophilized protein should be stored at -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at -20°C for 3 months. |
| Buffer/Preservatives | Lyophilized from a 0.2 μM filtered solution of 20mM PB, 150mM NaCl, pH 7.4. |
| Alternative names | Interleukin-31; IL-31 Read more... |
| Note | For research use only |
| Application notes | Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in 1X PBS. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. |
| Expiration Date | 6 months from date of receipt. |
