IL-21 Interleukin-21 Rat Recombinant Protein

IL-21 Interleukin-21 Rat Recombinant Protein

• 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.
• Synonyms: Interleukin-21; IL-21; Il21
• Gene Name: IL21
• UniProt: A3QPB9
• Reactivity: Rat
• Source: Escherichia coli
• Purification: Greater than 95.0% as determined by (a) Analysis by RP-HPLC and (b) Analysis by SDS-PAGE.
• Bioactivity: The biological activity is measured by its ability to proliferate activated B cells.
• Form: Sterile Filtered White lyophilized (freeze-dried) powder.
• Reconstitution: It is recommended to reconstitute the lyophilized Rat IL21 in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
• Components: Rat IL-21 was lyophilized from a 0.2µm filtered concentrated solution in PBS, pH 7.4.
• Storage Conditions: Lyophilized Rat IL-21 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Rat IL21 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
