Interleukin-11, IL-11, Adipogenesis inhibitory factor, AGIF, Oprelvekin, IL11.
IL11 Human Recombinant produced in Pichia Pastoris is a single, non-glycosylated, Polypeptide chain containing 177 amino acids (it differs from the 178 amino acid length of the native IL11 only in lack of the N-terminal praline residue) and having a molecular mass of 19kDa.
The IL11 is purified by proprietary chromatographic techniques.
It is recommended to reconstitute the lyophilized Interleukin -11 in sterile 18M?-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Please prevent freeze-thaw cycles.
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
Amino acid sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Gly-Pro-Pro-Pro-Gly.
The ED50 as determined by the dose-dependent stimulation of the proliferation of murine 7TD1 was found to be less then 0.2ng/ml, corresponding to a Specific Activity of 8,000,000 IU/ mg.
