PRODUCT SOURCE
Recombinant Human IL-1b /Interleukin-1b Protein (rh IL1B) Ala 117 - Ser 269 (Accession # NP_000567) was produced in E.coli cells at ACROBiosystems.
MOLECULAR CHARACTERIZATION
Mouse IL6ST /GP130 /CD130 Fc Chimera is fused with a human IgG1 Fc tag at the C-terminus, and has a calculated MW of 93.3 kDa. The predicted N-terminus is Gln 23. DTT-reduced Protein migrates as 120-130 kDa in SDS-PAGE due to glycosylation.
BIOLOGICAL ACTIVITY
The bio-activity was determined by dose-dependent stimulation of the proliferation of mouse D10.G4.1 cells. The ED50 < 2 pg/mL, corresponding to a specific activity of >500,000,000 Unit/mg.
PURITY
>97% as determined by SDS-PAGE.
ENDOTOXIN
Less than 1.0 EU per μg of the rh IL1B by the LAL method.
