Lyophilized Standard Mix-Human Group 5 Panel A, 8-Plex. PN: HG50008. One vial containing lyophilized recombinant human sE-Cadherin, sLIGHT, sTRAIL-R3, s4-1BB, sCD30L, sVEGFR2, BLyS, and sPECAM-1. 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 TNFRSF9/sCD137/s4-1BB. 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.

Tumor necrosis factor receptor superfamily member 9 (TNFRSF9) is a member of the tumor necrosis factor (TNF) receptor family; alternative names are sCD137 and 4-1BB. It is induced by lymphocyte activation (ILA) and is currently of interest to immunologists as a co-stimulatory immune checkpoint molecule. CD137 can be expressed by activated T cells, but to a larger extent on CD8 than on CD4 T cells. In addition, CD137 expression is found on dendritic cells, follicular dendritic cells, natural killer cells, granulocytes and cells of blood vessel walls at sites of inflammation. The best characterized activity of CD137 is its co-stimulatory activity for activated T cells. Crosslinking of CD137 enhances T cell proliferation, IL-2 secretion survival and cytolytic activity. Further, it can enhance immune activity to eliminate tumors in mice.
