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 PBS, pH 7.4. |
Alternative names | Interleukin-4; IL-4; B-cell stimulatory factor 1; 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. |
