Merck, HIGFBMAG-53K-07, MILLIPLEX® Human IGF Binding Protein Magnetic Bead Panel - Metabolism Multiplex Assay

Insulin-like growth factor (IGF) binding proteins (IGFBP) are expressed by multiple tissues and cells, including hepatic cells. By binding both IGF-1 and IGF-2, IGFBPs play a critical role in the regulation of IGF action, altering IGF interaction with cell surface receptors and increasing circulating IGF half-life and bioavailability. While their functions at the cellular level are not fully understood, studies have demonstrated the capacity to both stimulate and inhibit IGF-1 activity, depending on the system involved and the IGFBP studied. The ability of IGFBPs to regulate cell sensitivity by inhibiting IGF signaling may function in the control of tumor cell growth. The MILLIPLEX® Human IGF Binding Protein (IGFBP) Panel, is used for the simultaneous quantification of any or all of the following analytes in human serum, plasma, and cell culture conditioned-media samples: IGFBP-1, IGFBP-2, IGFBP-3, IGFBP-4, IGFBP-5, IGFBP-6, and IGFBP-7. This kit uses a 96-well format, contains a lyophilized standard cocktail, two internal assay quality controls and can measure up to 38 samples in duplicate. The Luminex® xMAP® platform uses a magnetic bead immunoassay format for ideal speed and sensitivity to quantitate multiple analytes simultaneously, dramatically improving productivity while conserving valuable sample volume. Panel Type: Endocrine
