Lyophilized Standard Mix - Rat Group 1 Panel A, 7-Plex. PN: RG10007. One vial containing lyophilized recombinant rat IFNγ, IL-2, IL-4, IL-6, IL-10, IL-17A, and TNFα.  Note: If multiple analyte kits on the above target list are ordered as a panel, only one vial of standard mix is supplied for those analyte kits.

STORAGE:  2-8 C in the dark.

IMPORTANT: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Interleukin-6 (Accession P20607) is a member of the interleukin cytokine family, though it displays some hormone-like properties that can affect many metabolic processes. IL-6 may act as a pro- or anti-inflammatory cytokine. It is primarily secreted by T-cells and macrophages to stimulate immune responses. It may be secreted during tissue damage or during bacterial infections. IL-6 is able to cross the blood-brain barrier. IL-6 supports the growth of B-cells and inhibits the proliferation of regulatory T-cells. It may also have the potential to improve anti-tumor activity in cancer immunotherapy.
