Short Description: Recombinant Human Interleukin-12 is produced by our Mammalian expression system and the target gene encoding Arg23-Ser219&Ile23-Ser328 is expressed.
Shipping: Ambient
Formulation: Lyophilized from a 0.2 m filtered solution of PBS, pH7.4.
Storage: Lyophilized protein should be stored at < -20C, though stable at room temperature for 3 weeks.
Reconstituted protein solution can be stored at 4-7C for 2-7 days.
Aliquots of reconstituted samples are stable at < -20C for 3 months.
Reconstitution: Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100 g /ml.
Dissolve the lyophilized protein in ddH2O.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
Purity: Greater than 95% as determined by reducing SDS-PAGE.
Endotoxin: Less than 0.1 ng/g (1 IEU/g) as determined by LAL test.
Background: IL-12 is a heterodimeric pleiotropic cytokine made up of a 40 kDa (p40) subunit and a 35 kDa (p35) subunit.Human and mouse IL12 share 70% and 60% amino acid sequence identity in their p40 and p35 subunits, respectively. IL-12 is involved in the differentiation of naive T cells into Th1 cells. It is known as a T cell-stimulating factor, which can stimulate the growth and function of T cells. It stimulates the production of interferon-gamma (IFN-) and tumor necrosis factor-alpha (TNF-) from T cells and natural killer (NK) cells, and reduces IL-4 mediated suppression of IFN-. T cells that produce IL-12 have a coreceptor, CD30, which is associated with IL-12 activity.IL-12 plays an important role in the activities of natural killer cells and T lymphocytes. IL-12 mediates enhancement of the cytotoxic activity of NK cells and CD8+ cytotoxic T lymphocytes.
