Description
Principle of the assay: human IGFBP6 ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for IGFBP6 has been precoated onto 96-well plates. Standards(NSO, A25-G240) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for IGFBP6 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human IGFBP6 amount of sample captured in plate.
Background: Insulin-like growth factor-binding protein 6 (IGFBP6) is a protein that in humans is encoded by the IGFBP6 gene. The IGFBP6 gene is mapped to chromosome 12. In all, it has contained 216 amino acid protein with a calculated molecular mass of 22,847, The human keratinocyte cell line HaCat secretes IGFBP6 as an autocrine growth inhibitor. Recombinant IGFBP6 was also shown to inhibit growth of HaCat cells and other keratinocyte cell lines
