Product name | Recombinant Mouse IL-21 Protein |
---|---|
Catalog No. | RP00664 |
Description | Recombinant Mouse IL-21 Protein is produced by E. coli expression system. The target protein is expressed with sequence (Pro25-Ser146) of mouse IL-21 (Accession #Q9ES17) fused with an initial Met at the N-terminus. |
Purity | > 95% by SDS-PAGE. |
Endotoxin | < 1 EU/μg of the protein by LAL method. |
Formulation | Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH7.4.Contact us for customized product form or formulation. |
Species | Mouse |
Storage | Store the lyophilized protein at -20°C to -80 °C for long term. After reconstitution, the protein solution is stable at -20 °C for 3 months, at 2-8 °C for up to 1 week. |

Reconstitution | Centrifuge the tube before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid votex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles. |
