Description | Recombinant Human Interleukin-13 is produced by our Mammalian expression system and the target gene encoding Gly35-Asn146 is expressed with a 6His tag at the C-terminus. | ||
Calculated Molecular Weight | Mol Mass:13.4 KDa; APMol Mass:13-30 KDa, reducing conditions | Formulation | Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4. |
Endotoxin | < 0.01 EU/µg as determined by LAL test. | Purity | Greater than 95% as determined by reducing SDS-PAGE. (QC verified) |
Biological Activity | Measured in a cell proliferation assay using TF‑1 human erythroleukemic cells.The ED50 for this effect is 1.5-4.5 ng/ml. (QC verified) | ||
Reconstitution | Always centrifuge tubes before opening.Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. | ||
Storage | Lyophilized protein should be stored at ≤ -20°C, stable for one year after receipt. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at ≤ -20°C for 3 months. | ||
Shipping | The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature listed below. | ||
Background | Interleukin-13 is also known as IL-13. It is a protein that in humans is encoded by the IL13 gene. Interleukin-13 is an immunoregulatory cytokine produced primarily by activated Th2 cells.It is involved in several stages of B-cell maturation and differentiation. It up-regulates CD23 and MHC class II expression, and promotes IgE isotype switching of B cells. This cytokine down-regulates macrophage activity, thereby inhibits the production of pro-inflammatory cytokines and chemokines. This cytokine is found to be critical to the pathogenesis of allergen-induced asthma but operates through mechanisms independent of IgE and eosinophils. |
