96 Tests PN: B113375

Components:

45x Ab-conjugated beads (S4P7 - human sTACI Ab-bead). PN: B113375A. One vial containing 100 µL of anti-human sTACI conjugated to AimPlex Bead S4P7.

25x Biotin-detection Ab (human sTACI Biotin-dAb). PN: B113375B. One vial containing 100 µL of biotinylated anti-human sTACI.

Lyophilized Standard Mix-Human Group 10, Panel B, 7-Plex. PN: HG1007B. One vial containing lyophilized recombinant Lymphotactin, MIA, Midkine, NOV, NRG1-beta1, sTACI, and sTRAIL. 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 Human TNFRSF13B/sCD267/sTACI. Can be multiplexed with other analytes in Human Group 10.  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:

TACI (Transmembrane Activator and CAML Interactor), also known as tumor necrosis factor receptor superfamily member 13B (TNFRSF13B) and CD267, is a transmembrane protein of the TNF receptor superfamily found predominantly on the surface of B cells, which are an important part of the immune system. TACI recognizes three ligands: APRIL, BAFF and CAML. TACI mutations are associated with immunodeficiency in humans, as a significant proportion of CVID patients have TACI mutations. People with this condition produce abnormally low amounts of antibodies, which are needed for protection against infections.  In humans, the gene encoding this protein is located within the Smith-Magenis syndrome region on chromosome 17. Diseases associated with TNFRSF13B include immunoglobulin a deficiency 2 and immunodeficiency, common variable, 2.
