Protein Sequence | MEIPMSTVVK ETLIQLSTHR ALLTSNETMR LPVPTHKNHQ LCIGEIFQGL DILKNQTVRG GTVEILFQNL SLIKKYIDGQ KEKCGEERRK TRHFLDYLQE FLGVMSTEWA MEV |
UniProt ID | Q08125 |
Source | E. coli |
Biological Activity | The ED50 was determined by the dose - dependent stimulation of the proliferation of human TF - 1 cells is 2 x 106 units/mg. |
Storage | The lyophilized IL-5 recombinant protein is stable for at least 2 years from date of receipt at -20˚°C. Reconstituted IL-5 is stable for at least 3 months when stored in working aliquots with a carrier protein at -20˚°C. As with any protein, exposing IL-5 recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature. |
Alternative names | Il-5, Interleukin-5, B-cell growth factor II, IL-5 |
