Synonyms: Interleukin-21, IL-21, Il21.

Description: Interleukin-21 Mouse Recombinant protein 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.

Source: Escherichia coli.

Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.

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

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.

Stability: Lyophilized Mouse IL-21 although stable at room temperature for 3 weeks, should be stored desiccated below -20°C. Upon reconstitution Mouse IL21 should be stored below -20°C.

For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).

Please avoid multiple freeze-thaw cycles.

Purity: Greater than 95.0% as determined by SDS-PAGE

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.

Usage: Unless otherwise mentioned in the product description this product is intended for LABORATORY RESEARCH USE ONLY.
