Mouse IL-12 Antibody Summary

Species Reactivity

Mouse

Specificity

Detects mouse IL-12 in direct ELISAs and Western blots. In direct ELISAs and Western blots (non-reducing and reducing conditions), this antibody shows less than 10% cross-reactivity with recombinant human IL-12.

Source

Polyclonal Goat IgG

Purification

Antigen Affinity-purified

Immunogen

S. frugiperda insect ovarian cell line Sf 21-derived recombinant mouse IL‑12
Mouse IL-12 heterodimer: Mouse IL-12 p40 (Met23-Ser335) Accession # P43432, Mouse IL-12 p35 (Arg23-Ala215) Accession # NP_032377

Formulation

Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.

Endotoxin Level

<0.10 EU per 1 μg of the antibody by the LAL method.

Label

Applications

Recommended Concentration

Sample

Western Blot

0.1 µg/mL

Recombinant Mouse IL‑12 (Catalog # 419-ML)

Neutralization

Measured by its ability to neutralize IL‑12-induced proliferation in PHA-activated mouse splenocytes. Mattner, F. et al. (1993) Eur. J. Immunol. 23:2202. The Neutralization Dose (ND₅₀) is typically 0.01-0.06 µg/mL in the presence of 1 ng/mL Recombinant Mouse IL‑12.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Cell Proliferation Induced by IL‑12 and Neutralization by Mouse IL‑12 Antibody. Recombinant Mouse IL-12 (Catalog # 419-ML) stimulates proliferation in PHA-activated mouse splenocytes in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Mouse IL-12 (1 ng/mL) is neutralized (green line) by increasing concentrations of Mouse IL-12 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-419-NA). The ND₅₀ is typically 0.01-0.06 µg/mL.

Background: IL-12

Interleukin 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 anti-tumor and anti-viral agent.

Human and mouse IL‑12 share 70% and 60% amino acid sequence identity in their p40 and p35 subunits, respectively. While mouse IL‑12 is active on both human and mouse cells, human IL‑12 is not active on murine cells. R&D Systems' recombinant mouse IL‑12 preparations were proteolytically cleaved between residues G158 and E159 of the mature p35 subunit. Thus, under reducing conditions, three bands representing the p40 subunit, the p35 R1 - G158 peptide and the p35 E159‑A193 peptide can be observed in SDS-PAGE. The biological activity of this cleaved mouse IL‑12 is comparable to that of the intact human IL‑12.
