Biological Activity

The ED50 as determined by the dose-dependant stimulation of the proliferation of TF-1 cells was found to be 1.7ng/ml, corresponding to a specific activity of 588,235.3IU/mg.

Formulation

Lyophilized from a concentrated (1mg/ml) solution containing 20mM Sodium Phosphate and 50mM NaCl pH-7.5.

Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Purity

Greater than 97.0% as determined by(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Solubility

It is recommended to reconstitute the lyophilized Mouse Interleikin-5 in sterile 18MΩ-cm H2O at a concentration of 100ug/ml, which can then be further diluted to other aqueous solutions.

Source

Escherichia Coli.

Stability

Lyophilized Mouse Interleukin-5 although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution Mouse IL5 should be stored at 4oC between 2-7 days and for future use below -18oC.
Please avoid freeze thaw cycles.
