Recombinant human IL-7 produced in HEK cells is a glycosylated monomer, having a molecular weight range of 19-30 kDa due to glycosylation. The IL-7 is purified by proprietary chromatographic techniques.
Synonyms: Lymphopoietin 1 (LP-1), pre-B cell factor, IL-7.
Formulation: The IL7 was lyophilized from 1mg/ml in 1xPBS.
Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
Purity: Greater than 95% as obsereved by SDS-PAGE.
Source: HEK.
Uniprot ACC number: P13232
Transportation method: Shipped at room temperature.
Stability: Lyophilized IL-7 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL7 should be stored at +4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
Biological Activity: The activity was determined by the dose dependent stimulation of the proliferation of murine 2E8 cells and is typically 0.3 ng/ml corresponding to a specific activity of 3, 333, 334units/mg.
Solubility: It is recommended to reconstitute the lyophilized IL-7 in sterile PBS containing 0.1% endotoxin-free recombinant HSA.
