["Measure by its ability to induce TF-1 cells proliferation. The ED50 for this effect is <0.2 ng/mL. The specific activity of recombinant human IL-4 is approximately >1 x 107 IU/mg. ,12 kDa"]Product Description
Interleukin-4 is the stated recombinant protein target for this Elabscience product. The listing uses collaborator-supplied specifications to support research-use-only protein selection through ABMIUM.
Protein profile: reactive species/source: Human; expression system: E.coli; physical form: Lyophilized from sterile PBS,pH 8.0.<br/>Normally 5% - 8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.<br/>Please refer to the specific buffer information in the printed manual.; tag: Human ,Interleukin-4 ,Cytokines; predicted molecular weight: 15.9 kDa.
Quality and formulation: purity: > 98 % as determined by reducing SDS-PAGE.; endotoxin: < 0.1 EU per μg of the protein as determined by the LAL method..
Functional evidence: activity: Measure by its ability to induce TF-1 cells proliferation. The ED<sub>50</sub> for this effect is <0.2 ng/mL. The specific activity of recombinant human IL-4 is approximately >1 x 10<sup>7</sup> IU/mg.. In the ABMIUM matrix, collaborator-supplied functional evidence is marked C; unsupported application columns remain N.
