IL 21 Mouse

Interleukin-21 Mouse Recombinant

Interleukin-21 Mouse Recombinant produced in E.Coli is a single, non-glycosilated polypeptide chain containing 130 amino acids and having a total molecular mass of 15kDa.
The Murine IL-21 is purified by proprietary chromatographic techniques.

Accession

Q9ES17

Amino acid sequence

The sequence of the first five N-terminal amino acids was determined and was found to be Met-His-Lys-Ser-Ser.

Biological Activity

The ED50=10 -50 ng/ml, determined by the cell proliferation assay of modified Ba/F3 cells.

Formulation

Mouse IL-21 was lyophilized from 20mM NaHCO3, pH 8.5.

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 Mouse 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 Mouse IL-21 although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution Mouse 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.
