PRODUCT SOURCE
Recombinant Human IL-4 /Interleukin-4 Protein,HEK293 expressed,ActiveMax (rh IL-4) His 25 - Ser 153 (Accession # AAH67514) was produced in human 293 cells (HEK293) at ACROBiosystems.
MOLECULAR CHARACTERIZATION
rh IL5RA /CD125 is fused with a polyhistidine tag at the C-terminus, and has a calculated MW of 37.7 kDa. The predicted N-terminus is Asp 21. DTT-reduced Protein migrates as 45-55 kDa in SDS-PAGE due to glycosylation.
BIOLOGICAL ACTIVITY
The bio-activity was determined by dose-dependent stimulation of the proliferation of TF-1 cells. The ED50 < 0.2 ng/mL, corresponding to a specific activity of >5X106 Unit/mg.
PURITY
>95% as determined by SDS-PAGE.
ENDOTOXIN
Less than 1.0 EU per μg of the rh IL-4 by the LAL method.
