IL 11 Human, Pichia

Interleukin-11 Human Recombinant, Pichia

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.

Accession

P20809

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.

Biological Activity

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.

Formulation

IL11 was lyophilized after extensive dialysis against 20mM PB, pH7.0 and 2% Glycine buffer.

Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Purity

Greater than 95.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Solubility

It is recommended to reconstitute the lyophilized Interleukin -11 in sterile 18MΩ-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Source

Pichia Pastoris.

Stability

Lyophilized IL11 although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution IL11 should be stored at 4oC between 2-7 days and for future use below -18oC.
Please avoid multiple freeze-thaw cycles.

Synonyms

Interleukin-11, IL-11, Adipogenesis inhibitory factor, AGIF, Oprelvekin, IL11.
