Recombinant Human Interleukin 12B (natural killer cell stimulatory factor 2, cytotoxic lymphocyte maturation factor 2, p40)

• Cat.No.: IL12B-670H
• Product Overview: Recombinant HumanIL12B is a glycosylated heterodimeric polypeptide containing 503 amino acids.

Specification

• Species: Human
• Source: CHO
• Tag: Non
• Description: This gene encodes asubunit of interleukin 12, a cytokine that acts on T and natural killercells, and has a broad array of biological activities. Interleukin 12 is adisulfide-linked heterodimer composed of the 40 kD cytokine receptor likesubunit encoded by this gene, and a 35 kD subunit encoded by IL12A.
• Form: Lyophilized from asterile filtered solution containing PBS, pH 7.4.
• Purity: >98% by HPLC andSDS-PAGE.
• Molecular Weight: 75 kDa; comprised ofdisulfide-bonded 35 kDa (p35) and 40 kDa (p40) subunits.
• Endotoxin Level: <0.1 ng/μg ofRecombinant Human IL12.
• Biological Activity: Determined by itsability to stimulate the proliferation of PHA-activated human T lymphoblasts.The ED50 for this effect is 0.1-0.2 ng/mL.

• Reconstitution: Centrifuge vialprior to opening. Add sterile distilled water or aqueous buffer containing0.1% BSA to a concentration of 0.1-1.0 mg/mL. Please note that the additionof any carrier protein into this product may produce unwanted endotoxin. Thisdepends upon the particular application employed. Further dilutions should bemade in appropriate buffered solutions.
• Storage: Stable at 2-8°C, butbest kept desiccated -20°C. Upon reconstitution, stable for up to 1 week at2-8°C. For longer term, store in working aliquots below -20°C. Avoid repeatedfreeze/thaw cycles.
