IL 7, Rat Recombinant, produced in
Escherichia coli is a single, non-glycosylated, polypeptide chain containing 129 amino acids and having a molecular mass of 15.0 kDa. The IL 7 is purified by proprietary chromatographic techniques.
Synonyms: Lymphopoietin 1 (LP-1), pre-B cell factor, IL-7.
Formulation: Lyophilized from a 0.2 µm filtered concentrated solution in PBS, pH 7.4.
Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
Purity: Greater than 98% as determined by SDS-PAGE.
Solubility: It is recommended to reconstitute the lyophilized IL-7 in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Stability: Lyophilized IL-7 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL-7 should be stored at +4°C between 2-7 days and for future use below -18°C. Please prevent freeze-thaw cycles.
Biological Activity: The ED50 was determined by the dose-dependent stimulation of the proliferation of murine 2E8 cells is less than 0.2ng/ml, corresponding to a specific activity of >5,000,000 IU/mg.
