Description générale
Insulin-like growth factor-binding proteins (IGF-BPs) form high affinity complexes with both insulin-like growth factor- I and II (IGF-I and IGF-II). Currently there are seven named IGF-BPs. Insulin-like growth factor-binding protein-1 (IGF-BP1) is a 25.4kDa cysteine-rich secreted protein. It is the most abundant IGF-BP in amniotic fluid and is expressed in liver, decidua and kidneys. Levels of IGF-BP1 in serum are lowest after food. It binds to both IGF-I and IGF-II with equal affinity. Phosphorylated IGF-BP1 hinders IGF actions, whereas non-phosphorylated IGF-BP1 is stimulatory. Recombinant human IGF-BP1 is a 25.4kDa protein consisting of 235 amino acid residues (Isoform A).
Actions biochimiques/physiologiques
Insulin-like growth factor-binding proteins (IGF-BPs) control the distribution, function and activity of insulin-like growth factors (IGFs) in various cell tissues and body fluids. They prolong the half-life of IGFs. Insulin-like growth factor-binding protein-1 (IGF-BP1) has been shown to have a role in the development and advancement of cancers. It is downregulated in hepatocellular carcinoma.

Reconstitution
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.

Insulin-like growth factor-binding protein-3 (IGFBP-3) regulates IGF bioactivity and also independently modulates cell growth and survival. By using a yeast two-hybrid screen to identify IGFBP-3-interacting proteins, we cloned humanin (HN) as an IGFBP-3-binding partner. HN is a 24-aa peptide that

A proper fetomaternal immune-endocrine cross-talk in pregnancy is fundamental for reproductive success. This might be unbalanced by exposure to environmental chemicals, such as bisphenol A (BPA). As fetoplacental contamination with BPA originates from the maternal compartment, this study investigated the
