Biological Activity

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

Description
Interleukin-21 Rat Recombinant produced in E.Coli is a single, non-glycosilated polypeptide chain containing 129 amino acids and having a total molecular mass of 15.2kDa.
The Rat IL-21 is purified by proprietary chromatographic techniques.

Rat IL-21 was lyophilized from a 0.2?m 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 18M?-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 -18¡ãC. Upon reconstitution Rat IL21 should be stored at 4¡ãC between 2-7 days and for future use below -18¡ãC. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.

Synonyms
Interleukin-21, IL-21, Il21.
