45x Ab-conjugated beads (S5P3 - Human IGFBP-3 Ab-bead). PN: B114563A. One vial containing 100 µL of anti-Human IGFBP-3 conjugated to AimPlex Bead S5P3.
25x Biotin-detection (Human IGFBP-3 Biotin-dAb). PN: B114563B. One vial containing 100 µL of biotinylated anti-Human IGFBP-3.
Lyophilized Standard Mix-Human Group 8, Panel A, 7-Plex. PN: HG81007. One vial containing lyophilized recombinant BMP-2, BMP-4, IGFBP-3, IGFBP-5, IGFBP-6, TIMP-1, and TIMP-2. 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 IGFBP-3. Can be multiplexed with other analytes in Human Group 8. 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.

IGFBP-3 is the major IGF binding protein present in serum of humans and animals. It is also present in the alpha granules of platelets. IGFBP-3 shows a similar affinity for IGF-1 and IGF-2. Smaller fragments of IGFBP3 consisting of various C- or N-terminally truncated forms have been described also. IGFBP3 inhibits follicle stimulating hormone. Markedly decreased levels of IGFBP3 are observed in patients with Growth hormone deficiencies (see also: Laron-type dwarfism), while markedly elevated levels are observed in patients with high levels of Growth hormone (acromegaly). In murine fibroblasts the synthesis of IGFBP3 is stimulated by mitogenic growth factors such as Bombesin, Vasopressin, PDGF, and EGF. In human skin fibroblasts the synthesis of IGFBP3 is stimulated by TGF-beta. Diseases associated with IGFBP3 include malignant mesenchymal tumor and marasmus.
