| 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. Recombinant human IL-12 p40 is a 40kD protein containing 306 amino acid residues (23-328). | | | Catalog # | I8434-31B1 | | Endotoxin | 0.1ng per ug (1EU/ug) | | Storage and Stability | Lyophilized powder may be stored at -20°C.
