96 Tests PN: B511128

Components:

45x Ab-conjugated beads (S4P4 - Canine IFNγ ab-bead). PN: B511128A. One vial containing 100 μL of anti-canine IFNγ conjugated to AimPlex Bead S4P4.

25x Biotin-detection Ab (Canine IFNγ Biotin-dAb). PN: B511128B. One vial containing 100 μL of biotinylated anti-canine IFNγ.

Lyophilized Standard Mix-Canine Group 1 Panel A, 10-Plex. PN: KG10010. One vial containing lyophilized recombinant IFNγ, IL-2, IL-6, IL-8, IL-10, IL-12p40, IL-17A, MCP-1, SCF 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.

Application: Optimal antibody pair and antigen standard for assaying human IFNγ.  Can be multiplexed with other analytes in Canine Group 1.  To be used in conjunction with the AimPlex NR Basic Kit (PN: P100001) and a diluent kit. Refer to the AimPlex Multiplex Immunoassay User Manual and kit inserts for the assay procedure.

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.

Description:

Interferon-gamma (Accession P42161) also known as immune interferon is produced by a variety of leukocytes, most notably T-cells and NK cells. IFN-γ is involved in nearly every phase of immune and inflammatory responses. IFN-γ assists in anti-tumor responses and more generally, in inter-cellular communication for both innate and adaptive immune responses. Interferon-gamma promotes development and activation of Th1 cells, Ig switching in B-cells, and activation of macrophages.

In mice and humans, interferon gamma has been linked to many autoimmune diseases such as non-obese diabetes, lupus nephritis, and experimental autoimmune thyroiditis. There is research to suggest that IFN-γ not only promotes inflammation but may also limit inflammation in certain circumstances by exhibiting anti-proliferative and apoptotic effects. IFN-γ has been used in experimental studies for treating multiple sclerosis, but it appears to have exacerbated the condition.
