Components:

45x Ab-conjugated beads (S5P5 - human sTNFRI Ab-bead). PN: A113305A. One vial containing 100 µL of anti-human sTNFRI conjugated to AimPlex Bead S5P5.

25x Biotin-detection Ab (human sTNFRI Biotin-dAb). PN: A113305B. One vial containing 100 µL of biotinylated anti-human sTNFRI.

Lyophilized Standard Mix-Human Group 5 Panel B, 10-Plex. PN: HG50010. One vial containing lyophilized recombinant human sRANKL, sEndoglin, sVCAM-1, sE-selectin, sCD95L, sICAM-1, sCD25, sCD14, sTNFRI, and sCD40L.  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 TNFRSF1A/sCD120a/sTNFR1. Can be multiplexed with other analytes in Human Group 5.  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:

Tumor necrosis factor receptor 1 (TNF R1), also known as tumor necrosis factor receptor superfamily member 1A (TNFRSF1A) and CD120a, is a ubiquitous membrane receptor that binds tumor necrosis factor-alpha (TNFα). Germline mutations of the extracellular domains of this receptor were found to be associated with the human genetic disorder called tumor necrosis factor associated periodic syndrome (TRAPS) or periodic fever syndrome. Impaired receptor clearance is thought to be a mechanism of the disease. Mutations in the TNFRSF1A gene is associated with elevated risk of multiple sclerosis. Serum levels of TNFRSF1A are elevated in schizophrenia and bipolar disorder, and high levels are associated with more severe psychotic symptoms. High serum levels are also associated with cognitive impairment and dementia. Diseases associated with TNFRSF1A include multiple sclerosis 5 and periodic fever.
