Background:
IL-11 is a thrombopoietic growth factor that directly stimulates the proliferation of hematopoietic stem cells and megakaryocyte progenitor cells and induces megakaryocyte maturation resulting in increased platelet production.
IL-11 is a member of a family of human growth factors which includes human growth hormone, granulocyte colonystimulating factor and other growth factors.
Description:
The protein is produced in P. Pichia by recombinant DNA technology. The protein has a molecular mass of approximately 19,000 Daltons and is non-glycosylated. The protein is 177 amino acids in length and differs from the 178 amino acid length of native IL-11 only in lacking the amino-terminal praline residue.
Quality Control:
Biological activity: The ED50 as determined by the dose-dependant stimulation of the proliferation of murine 7TD1 was found to be less then 0.2ng/ml, corresponding to a Specific Activity of 8.0 x 106 IU/ mg.
Purity: Greater than 95% as determined by
        (a) Analysis by SEC-HPLC.
        (b) Analysis by reducing and non-reducing SDS-PAGE Silver Stained gel.
Molecular weight: 19.2KD+/-10% determined by reduced SDS-PAGE.
Isoelectric Point: More than 11.
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.
Endotoxin: Less than 0.02ng/µg (0.2 IEU/µg) determined by LAL test.

Formulation:
The protein was lyophilized from a concentrated (1mg/ml) solution with no additives.
Storage:
Lyophilized rHuIL-11 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C.
Upon reconstitution rHuIL-11 should be stored at 4°C between 2-7 days and for future use below -18°C. For longterm storage it is recommended to add a carrier protein (0.1% HSA or BSA).
   Please avoid freeze-thaw cycles.
Reconstitution:
It is recommended to reconstitute the lyophilized rHuIL-11 in sterile 18MΩ-cm H₂O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
