Sandwich ELISA quantitative detection kit for Human IGFBP-1 in cell culture supernates, serum, plasma (heparin, EDTA) and urine. IGFBP1 is also known as amniotic fluid binding protein (AFBP), placental protein-12, alpha-pregnancy-associated endometrial globulin, growth hormone independent binding protein, binding protein-28, binding protein-26, and binding protein-25.1 The low-molecular weight insulin-like growth-factor binding protein (IGF-BP25) is synthesized by human liver, secretory endometrium and decidua, and is also present in human serum. It binds insulin-like growth factors IGF-I and IGF-II with high affinity, and is proposed to act as a paracrine regulator of cell growth.2 These IGF-binding proteins are expressed at different concentrations in different tissues and are thought to regulate the activity of IGF I and II.3 The gene is organized in four exons and spans 5.9 kb.4 The IBP-1 gene is a single copy gene, located on chromosome 7.5 The standard product used in this kit is recombinant human IGFBP-1, consisting of 234 amino acids with the molecular mass of 25kD. Assay Range: 31.2pg/ml-2000pg/ml Sensitivity: < 1 pg/ml Crossreactivity: There is no detectable cross-reactivity with other relevant proteins.
