IL12 Protein (AA 23-328, AA 57-253) (His tag)

Catalog No. ABIN7278665

Product Details

Target: IL12 (Interleukin 12 (IL12))

Protein Type: Recombinant

Biological Activity: Active

Protein Characteristics: AA 23-328, AA 57-253

Origin: Human

Source: HEK-293 Cells

Purification tag / Conjugate: This IL12 protein is labelled with His tag.

Purpose: IL-12 (human) (rec.) (His)

Specificity: The human IL-12 complex composed of the p40 subunit (aa 23-328) and the p35 subunit (aa 57-253) is fused at the C-terminus through a (G3S)4 linker to a His-tag.

Characteristics: Protein. The human IL-12 complex composed of the p40 subunit (aa 23-328) and the p35 subunit (aa 57-253) is fused at the C-terminus through a (G3S)4 linker to a His-tag. Source: HEK 293 cells. Endotoxin content: <0.01EU/μg protein (LAL test, Lonza). Lyophilized from 0.2μm-filtered solution in PBS. Purity: >95 % (SDS-PAGE). Interleukin-12 (IL-12), also known as Natural Killer Cell Stimulatory Factor (NKSF) or Cytotoxic Lymphocyte Maturation Factor (CLMF), is a heterodimeric pleiotropic cytokine made up of a 40 kDa (p40) subunit and a 35 kDa (p35) subunit. IL-12 is produced by macrophages and B lymphocytes and has been shown to have multiple effects on T cells and Natural Killer (NK) cells. Some of these IL-12 activities include the induction of IFN-gamma and TNF in resting and activated T and NK cells, the enhancement of cytotoxic activity of resting NK and T cells, the stimulation of resting T cell proliferation in the presence of a comitogen, and the enhancement of NK cell proliferation. Current evidence indicates that IL-12 is a key mediator of cellular immunity and induces the differentiation of Th1 cells from precursor T helper cells. Based on its activities, it has been suggested that IL-12 may have therapeutic potential as a vaccine adjuvant that promotes cellular immunity and as an antitumor and anti viral agent.

Purity: >95 % (SDS-PAGE)

Endotoxin Level: <0.01EU/μg protein (LAL test, Lonza).

Biological Activity Comment: The ED50 was determined by the induction of IFN-gamma from NK cells co-stimulated with IL-18 is < 1.0 ng/ml, corresponding to a specific activity of >1 x 106units/mg.
