Human IL-28B Recombinant
$160.00 – $3,500.00
| accession | Q8IZI9 |
| Source | DNA sequence encoding mature chain of Human IL28B to a C-terminal polyHis tag was expressed in CHO cells. |
| Molecular weight | Recombinant Human Interleukin-28B (Interferon lambda) is a monomer consisting of 186 amino acid residue , and migrates as an approximately23 kDa protein under reducing conditions in SDS-PAGE. |
| Purity | >97%, as determined by SDS-PAGE |
| Biological Activity | The activity was determined by a WISH cell viral resistance assay with a linear range of 4-20 ng/ml . |
| Endotoxin | Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg). |
| Presentation | Recombinant Human Interleukin-28B was lyophilized from a 0.2 μm filtered PBS solution pH 7.4. |
| Reconstitution | A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers. |
| Storage | The lyophilized protein is stable for at least 2 years from date of receipt at -20° C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8° C for one month, or at -20° C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles. |
| Usage | This cytokine product is for research purposes only.It may not be used for therapeutics or diagnostic purposes. |
| Biological Process | Antiviral-defense |
| Molecular function | Cytokine |
