Precision
Intra-assay Precision (Precision within an assay): CV%<8%
Three samples of known concentration were tested twenty times on one plate to assess.
Inter-assay Precision (Precision between assays): CV%<10%
Three samples of known concentration were tested in twenty assays to assess.
Linearity
To assess the linearity of the assay, samples were spiked with high concentrations of rat IGFBP-1 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Target Background

Function
(From Uniprot)
IGF-binding proteins prolong the half-life of the IGFs and have been shown to either inhibit or stimulate the growth promoting effects of the IGFs on cell culture. They alter the interaction of IGFs with their cell surface receptors. Promotes cell migration.
Gene References into Functions
  1. In simulated sleep apnea hypopnea syndrome, intermittent hypoxia in young rats does not cause physical growth retardation, but serum IGF-1 and IGFBP-3 levels decreased with the increase of hypoxia and decline of oxygen saturation. PMID: 22805023
  2. up-regulation of IGFBP-1 in oligodendrocytes in multiple sclerosis may serve two functions: (i) regulate IGF-1 actions, (ii) exert IGF-independent effects through its RGD sequence PMID: 20345750
  3. Insulin regulation of insulin-like growth factor-binding protein-1 gene expression PMID: 11784721
  4. regulation of expression by insulin is impaired by presence of hydrogen peroxide PMID: 11942857
  5. IGFBP-1 and IGFBP-3 are present in phosphorylated form in fasted rat skin, which induced inhibition of collagen biosynthesis in cultured fibroblasts PMID: 12670795
  6. IGFBP-1 released during the early steps of liver tissue damage and repair may interact with liver cells and potentiate the sensitivity of IGF-I to mitogenic signals. PMID: 15070850
  7. In this report we demonstrate that in H4IIE-C3 cells, four distinct classes of GSK-3 inhibitor mimic the effect of insulin on a third thymine-rich insulin response element-containing gene, IGFBP-1. PMID: 15350195
  8. Iron, radical oxygen species, and HIF-2 and -3 as well as prolyl hydroxylase pathways play important roles in mediating effects of hypoxia on IGFBP-1 gene expression in liver. PMID: 16166214
  9. insulin inhibition of IGFBP-1 mRNA levels can occur in the absence of the phosphorylation of Foxo1/Foxo3, whereas activation of the mTOR pathway is both necessary and sufficient PMID: 16455781
  10. Activation of the mTOR pathway, without activation of its upstream regulator PI 3-kinase, reduces IGFBP1 expression. PMID: 17032741
  11. Age-related oxidative stress underlies the upregulated JNK activation and IGFBP-1 expression. PMID: 17645865
