CAT No.BT-CYT-684

Interleukin-21 Mouse Recombinant, IL 21 Mouse, 10ug

---

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.

Description
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.

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 18M¦¸-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 -18¡ãC. Upon reconstitution Mouse 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.
