Active Recombinant Mouse LIF,His-tagged

• Cat.No.: Lif-8869M
• Product Overview: Recombinant Mouse LIF was produced in the endosperm tissue of barley grain (Hordeum vulgare).

Specification

• Description: LIF (leukemia inhibitory factor, myeloid leukemia inhibitory factor) a pleiotropic lymphoid factor was initially described as a factor that inhibits the proliferation of myeloid leukemia cells and induces their differentiation into macrophages. Other activities of LIF include inhibition of adipogenesis, cholinergic neuron differentiation and bone metabolism.
• Source: Hordeum vulgare
• Species: Mouse
• Predicted N Terminal: His
• Form: PBS, pH 7.2, sterile filtered.
• Bio-activity: The bioactivity of murine LIF was determined by its ability to induce differentiation of murine M1 myeloid leukemia cells. The ED50 value for this effect is typically< 1 ng/ml, corresponding to a specific activity of>5 x 10e7 U/mg (where 50 U is defined as the amount of mLIF required to induce differentiation of 50% of M1 cells). The activity is comparable to mLIF from other commercial sources.
• Molecular Mass: Recombinant mouse LIF contains 188 amino acids and a 16 a.a. Histidine-based tag for a total length of 204 a.a. and has a predicted molecular mass of 22.8 kDa. As a result of glycosylation, the recombinant protein migrates with an apparent molecular mass of 28-30 kDa in SDS-PAGE.
• Endotoxin: Endotoxin level is less than 0.05EU/μg as measured by turbidimetric kinetic assay.
• Purity: >95% by SDS-PAGE gel analysis.
• Storage: The lyophilized protein is stable at room temperature for few weeks. Reconstituted protein should be used immediately or stored in working aliquots at -20°C. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended to reconstitute the lyophilized protein in sterile water to a concentration of no less than 100 μg/ml. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
