Source:Recombinant protein corresponding to human Interleukin 13 expressed in E. coli.
Molecular Weight:~17kD
Endotoxin: ~0.1ng/ug
Biological Activity:ED50 range =2.0-6.0ng/ml, determined by the dose dependent proliferation of human TF-1 cells. The optimal concentration for each specific application should be determined by an initial dose response assay.
Storage and Stability:Lyophilized powder may be stored at -70°C. Reconstitute to nominal volume by adding ddH2O . Aliquot and store at -20°C. Reconstituted product is stable for 12 months at -70°C. 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.
