PRODUCT SOURCE
Recombinant Human LIF Protein,HEK293 expressed,ActiveMax (rh LIF) Ser 23 - Phe 202 (Accession # AAH69540.1) was produced in human 293 cells (HEK293) at ACROBiosystems.
MOLECULAR CHARACTERIZATION
rh MICA is fused with a polyhistidine tag at the C-terminus, and has a calculated MW of 33.6 kDa. The predicted N-terminus is Glu 24. DTT-reduced Protein migrates as 45-65 kDa in SDS-PAGE due to glycosylation.
BIOLOGICAL ACTIVITY
Determined by its ability to stimulate the proliferation of human TF-1 cells. The ED50 <0.1 ng/mL, corresponding to a specific activity of >1X107 Unit/mg.
PURITY
>95% as determined by SDS-PAGE.
ENDOTOXIN
Less than 1.0 EU per μg of the rh LIF by the LAL method.
