Oncostatin-M Human Recombinant ( OSM Human )

Data sheet

Formulation

Lyophilized from a concentrated (1mg/ml) solution containing PBS pH-7.4.

Solubility

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

Purity

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

Description

Oncostatin-M Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 227 amino acids and having a molecular mass of 26kDa. The OSM is purified by proprietary chromatographic techniques.

Protein Background

Oncostatin M is a member of a cytokine family that includes leukemia-inhibitory factor, granulocyte colony-stimulating factor, and interleukin 6. This gene encodes a growth regulator which inhibits the proliferation of a number of tumor cell lines. It reg

Expression host

Escherichia Coli.

Synonyms

OSM, MGC20461.

Reagent Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Stability

Lyophilized Oncostatin M although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Oncostatin should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommend
