| Category | Proteins |
| Description | Human IL31 recombinant produced in E.coli is a single, non-glycosylated, polypeptide chain containing 141 amino acids (24-164 a.a.) and having a molecular mass of 15.8 kDa. |
| Tested applications | FA, HPLC, SDS-PAGE |
| Purity | > 95.0% as determined by(a) Analysis by SEC-HPLC.(b) Analysis by SDS-PAGE. |
| Conjugation | Unconjugated |
| Target | IL31 |
| Solubility (25°C) | It is recommended to reconstitute the lyophilized IL-31 in sterile H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions. |

| Biological Origin | E.coli |
| Biological Activity | The ED50 was determined by its ability to activate STAT following receptor ligand interaction and found to be < 5ng/ml, corresponding to specific activity of 200,000 units. |
| Storage | Store at 4°C for up to two weeks. For long term storage, aliquot and store at -20°C, avoid freeze/thaw cycles. |
| Buffer/Preservatives | The ED50 was determined by its ability to activate STAT following receptor ligand interaction and found to be < 5ng/ml, corresponding to specific activity of 200,000 units.. The IL-31 (1mg/ml) was lyophilized with 20 mM Phosphate buffer, 150mM NaCl pH-7.4. |
