Biological Activity

The biological activity is measured by its ability to proliferate activated B cells.

Formulation

Rat IL-21 was lyophilized from a 0.2um filtered concentrated solution in PBS, pH 7.4.

Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Purity

Greater than 95.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Solubility

It is recommended to reconstitute the lyophilized Rat IL21 in sterile 18MΩ-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Source

Escherichia Coli.

Stability

Lyophilized Rat IL-21 although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution Rat IL21 should be stored at 4oC between 2-7 days and for future use below -18oC. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please avoid multiple freeze-thaw cycles.

Synonyms

Interleukin-21, IL-21, Il21.
