Recombinant Human Interleukin 12B

• Cat.No.: IL12B-177H
• Product Overview: Recombinant human IL-12 p40 is a 40 kDa protein containing 306 amino acid residues. It was expressed in E.Coli.

Specification

• Cat. No.: IL12B -177H
• Description: Interleukin-12 is a disulfide-linked heterodimeric protein (p70), composed of two subunits, p35 and p40, which are encoded by two different genes. Accumulating data indicate that p40 secretion precedes that of IL-12 expression. In addition, to its ability to covalently bind to p35 to form IL-12, p40 can bind to p19 to form IL-23.
• Source: E.Coli.
• Purity: > 95% by SDS-PAGE and HPLC analysis.
• Endotoxin Level: < 0.1 ng per μg of IL-12p40.
• Stabilizer: None.
• Formulation: Lyophilized.
• Biological Activity: Not available.
• Reconstitution: The human IL-12p40 should be reconstituted in water to a concentration of 0.1-1.0 mg/ml. This solution can be diluted in water or other buffer solutions or stored at -20°C.
• Stability: The lyophilized protein is stable for a few weeks at room temperature, but best stored at -20°C. Reconstituted human IL-12p40 should be stored in working aliquots at -20°C. Avoid repeated freeze-thaw cycles.
