Mouse IL-21 Recombinant Protein Tag Free Lyophilized from Innovative Research has been recombinantly produced in E. coli. This is a Lyophilized protein buffered in Lyophilized from a 0.2 um filtered solution of 20mM PB,150mM NaCl,pH7.4. It is not recommended to reconstitute to a concentration less than 100UG/ml. Dissolve the lyophilized protein in ddH2O. with a purity of Greater than 95% as determined by reducing SDS-PAGE.Endotoxin level less than 0.1 ng/ug (1 IEU/ug) as determined by LAL test..More Details: Species: Mouse Target: Il21 Purity: Greater than 95% as determined by reducing SDS-PAGE.Endotoxin level less than 0.1 ng/ug (1 IEU/ug) as determined by LAL test. Source: E. coli Storage Conditions: Lyophilized protein should be stored at -20░C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7░C for 2-7 days.Aliquots of reconstituted samples are stable at -20░C for 3 months. Additional Information:Interleukin-21 also known as IL-21 is a protein that in mouse is encoded by the IL21 gene, belongs to the IL-15/IL-21 family. Interleukin-21 is a cytokine that has potent regulatory effects on cells of the immune system, including natural killer (NK) cells and cytotoxic T cells that can destroy virally infected or cancerous cells. This cytokine induces cell division/proliferation in its target cells.This recombinant protein can be used for biological assays. For research use only. . At Innovative Research we provide reliable, consistent products that deliver reliable, consistent results.
