Human quantitative IGF signaling antibody arrays on glass slides are multiplex protein microarray platforms used to measure selected components of the insulin-like growth factor (IGF) system simultaneously in biological samples. The IGF network contributes to cell growth, proliferation, survival and metabolism through interactions involving IGF ligands, receptors and IGF-binding proteins (IGFBPs). Alterations in IGF-related protein expression have been investigated in cancer biology and other areas of biomedical research.
Key Features
-
Multiplex protein quantification: Simultaneous measurement of selected human IGF-related proteins, potentially including IGF-1, IGF-2, IGF-1R, IGF-2R, insulin and specific IGFBPs, depending on the array.
-
Glass-slide microarray format: Immobilized capture antibodies enable parallel protein detection. Fluorescence-based signal measurement and comparison with protein standards support quantitative analysis.
-
Multiple sample types: Depending on assay validation, compatible samples may include serum, plasma, cell culture supernatants, cell lysates and tissue lysates.
-
Comparative protein profiling: Enables the comparison of IGF-related protein abundance across experimental conditions or biological samples.
Usual Research Applications
Human quantitative IGF signaling arrays support research into growth factor regulation, cancer-associated alterations in the IGF system and relationships between IGF-related proteins and cellular processes. They provide complementary protein-level data for investigating IGF-related networks but do not directly measure receptor activation, phosphorylation or downstream pathway activity.
