Description générale
IL-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 40.0 kDa protein containing 306 amino acid residues.
The interleukin-12 subunit β (IL12β) gene is localized on human chromosome 5q31–33. The encoded protein is part of IL-12, which is a heterodimer. It is mainly expressed by antigen-presenting cells (APCs).
Actions biochimiques/physiologiques
IL-12 is a disulfide-linked heterodimeric protein (p70), composed of two subunits, p35 and p40, which are encoded by two different genes. Recombinant human IL-12 p40 is a 40.0 kDa protein containing 306 amino acid residues.
Interleukin-12 subunit β (IL12β) is an immunoregulatory cytokine. It is involved in pathogenic defense responses and is also suggested as an anticancer therapeutic agent. IL12B is responsible for polarizing naive CD4+ cells toward a TH1 (T helper) phenotype and inducing IFN-γ (interferon) secretion by T and natural killer (NK) cells. This protein also stimulates the differentiation of cytotoxic CD8+ cells and enhances the activity of NK cells. IL12B is linked with many autoimmune diseases, such as psoriasis, systemic lupus erythematosus, Crohn′s disease and ulcerative colitis.

Forme physique
Lyophilized from 1x PBS, pH 7.2.
Reconstitution
Centrifuge the vial prior to opening. Reconstitute in 1x PBS, pH 7.2 to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
