Cat. No. : |
Il4-469M |
Description : |
Mouse Interleukin-4, also known as BCDF or BCGF, is a pleiotropic immunoregulatory cytokine. IL-4 activity is mediated through the IL-4R receptor. |
Species : |
Mouse |
Source : |
E.coli |
Form : |
Lyophilized with no additives. |
Purity : |
Purity Greater than 95% as determined by: Analysis by RP-HPLC. Reducing and non-reducing SDS-PAGE. |
Bio-activity : |
Recombinant mouse IL-4 is fully biologically active when compared to standards. The ED50, as determined by dose-dependent induction of HT-2 cell proliferation, is 2.5 ng/ml. |
Physical Appearance : |
Sterile Filtered white lyophilized (freeze-dried) powder. |
Solubility : |
Centrifuge vial before opening. When reconstituting the product, gently pipet and wash down the sides of the vial to ensure full recovery of the protein into solution. It is recommended to reconstitute the lyophilized product with sterile water at a concentration of 0.1 mgμs/ml, which can be further diluted into other aqueous solutions. |
Purity Greater than 95% as determined by : |
Analysis by RP-HPLC. Reducing and non-reducing SDS-PAGE. |
Protein Content determined by : |
UV spectroscopy at 280 nm. Analysis by RP-HPLC calibrated against a known standard. Quantitation on SDS-PAGE against a known standard. |
Endotoxin Level : |
Endotoxin level as measured by LAL is <0.01ng/ug or <0.1EU/ug. |
Amino acid sequence : |

Storage : |
Lyophilized product is very stable at -20 degrees. Reconstituted material should be aliquoted and frozen at -20. It is recommended to add a carrier protein (0.1% HSA or BSA) for long term storage. |
Pathways : |
Cytokine-cytokine receptor interaction; Fc epsilon RI signaling pathway; Hematopoietic cell lineage; Jak-STAT signaling pathway; T cell receptor signaling pathway |
