Product Specifications
Product Name Alternative
Interleukin-21, IL-21, Il21.
Source
Escherichia Coli
Purity
Greater than 95.0% as determined by (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
Bioactivity
The ED50=10 -50 ng/ml, determined by the cell proliferation assay of modified Ba/F3 cells.
Form
Sterile Filtered White lyophilized (freeze-dried) powder.
Solubility
It is recommended to reconstitute the lyophilized Mouse IL21 in sterile 18MΩ-cm H2O not less than 100μg/ml, which can then be further diluted to other aqueous solutions.
Storage Conditions
Stability: Lyophilized Mouse IL-21 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Mouse IL21 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA) .Please prevent freeze-thaw cycles
