| Recombinant human IL-6 is a 20.5kD protein containing 184 amino acid residues. | | | Catalog # | I8428-05 | | Biological Activity | ED50 as determined in a IL-6 dependent cell proliferation assay using 7TD1 cells is 0.1ng/ml, which corresponds to a speci c activity 1x10e7units/mg. | | Storage and Stability | Lyophilized: Stable for 2 years at 4°C. | | Reconstituted: Solutions 100ng/ul may be stored for 3 months at -20°C without detectable loss of activity. Less concentrated solutions stored at -20°C are less stable. Aliquot to avoid repeated freezing and thawing. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer with 0.5% BSA. | | Molecular Weight | 20.5kD | | Source | Human, recombinant expressed in E. coli | | Purity | 95% | | Endotoxin | 0.1ng/ug | | Concentration | ~0.1mg/ml | | Form | Supplied as a lyophilized powder from 10mM acetic acid, carrier free. Filtered through a 0.2um membrane and packaged aseptically. | | Reconstitution | Reconstitute with 10mM acetic acid to a concentration of 0.1-0.5mg/ml. Further dilition can be made with aqueous buffer containing 0.5% BSA. Note |
