Components:

45x Ab-conjugated beads (S4P4 - human sCD40 Ab-bead). PN: B113330A. One vial containing 100 µL of anti-human sCD40 conjugated to AimPlex Bead S4P4.

25x Biotin-detection (human sCD40 Biotin-dAb). PN: B113330B. One vial containing 100 µL of biotinylated anti-human sCD40.

Lyophilized Standard Mix-Human Group 9 Panel A, 8-Plex. PN: HG9008A. One vial containing lyophilized recombinant human sFas, sICAM-3,  sL-selectin, sP-selectin, sIL-1RI, sVEGFR1, sCD40, and sNCAM-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 Human TNFRSF5/sCD40. Can be multiplexed with other analytes in Human Group 9.  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 Superfamily, Member 5 (TNFRSF5) is a member of the TNF-receptor superfamily is also known as CD 40 antigen. This receptor has been found to be essential in mediating a broad variety of immune and inflammatory responses including T cell-dependent immunoglobulin class switching, memory B cell development, and germinal center formation. AT-hook transcription factor AKNA is reported to coordinately regulate the expression of this receptor and its ligand, which may be important for homotypic cell interactions. Adaptor protein TNFR2 interacts with this receptor and serves as a mediator of the signal transduction. The interaction of this receptor and its ligand is found to be necessary for amyloid-beta-induced microglial activation, and thus is thought to be an early event in Alzheimer disease pathogenesis. Diseases associated with CD40 include immunodeficiency with hyper-IgM, type 3 and CD40 deficiency.
