COMPONENTS

45x Ab-conjugated beads (S4P3 - human TNFα Ab-bead). PN: A111209A. One vial containing 100 µL of anti-human TNFα conjugated to AimPlex Bead S4P3.

25x Biotin-detection Ab (human TNFα Biotin-dAb). PN: A111209B. One vial containing 100 µL of biotinylated anti-human TNFα.

Lyophilized Standard Mix-Human Group 1 Panel A, 7-Plex. PN: HG10007. One vial containing lyophilized recombinant 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.

Description:

Tumor Necrosis Factor alpha (Accession P01375) is a member of the TNF Superfamily. TNF-α is produced by a variety of leukocytes, though mostly by activated macrophages. As an immune cell regulator with many roles, TNF-α may also induce fever, apoptosis or necrosis. Abnormal TNF-α production has been correlated to major depression, Alzheimer’s disease, cancer, psoriasis, and inflammatory bowel disease. TNF-α is also associated with insulin resistance, due to its over expression in adipose tissue in obese rodents and humans. Tumor necrosis factor alpha, additionally, has links to the pathologies of neuropathic pain and a compounding effect on malignancy-associated hypercalcemia with parathyroid hormone-related protein.
