IGFBP-1 human
 

IGFBP-1 (Insulin-like growth factor binding protein 1) is part of the IGF-System and one of seven binding proteins which bind IGF-I with high affinity. It has a molecular weight of 25.3kDa, 18 cysteins and is post-translational modified by phosphorylation, which affects the IGF-I affinity. IGFBP-1 expression is inhibited by insulin and stimulated by cortisol and glucagon. Thus, it is recommend to use a standard sampling procedure to avoid influence of e.g. food intake. IGFBP-1 is discussed in literature as a possible biomarker for preeclampsia .

The  Mediagnost IGFBP-1 ELISA allows the reliable measurement of human IGFBP-1 in serum, plasma and amniotic fluid.  An overview of major assay characteristics is given in the table below. More detailed information is available in the package insert and for special requirements or questions please contact us directly by email or phone.
