FGF-23 (Fibroblast growth factor 23) is a regulator of phosphate homeostasis. It upregulates EGR1 expression in the presence of KLBy. Acts directly on the parathyroid to decrease PTH secretion. Regulates the vitamin-D metabolism. Negatively regulates osteoblast differentiation and matrix mineralization. Defects in...

Signal peptide and extracellular domain of mouse DLL4 (amino acids 1-532) is fused at the C-terminus to the Fc portion of human IgG1. Inhibits adipogenesis of 3T3L-1 cells. Liquid. 0.2µm-filtered solution in PBS. The Notch ligand delta-like protein 4 (DLL4) is expressed highly and selectively within the arterial...

Human CTRP5 (amino acids 16-243) is fused at the N-terminus to a His-tag. Lyophilized from a 0.2µm-filtered solution in 55mM TRIS-Cl, pH 8.2, containing 150mM NaCl. CTRP5 (C1qTNF-related protein 5, C1QTNF5) belongs to a highly conserved family of adiponectin paralogs. CTRP5 mediates activation of AMP-activated...

Human RBP4 (amino acids 19-201) is fused at the N-terminus to a FLAG(R)-tag. Liquid. 0.2µm-filtered solution in PBS, pH 7.2. Retinol binding protein 4 (RBP4, RBP) is a 21kDa secreted protein, a member of the lipocalin family and is known as the primary transporter of retinol (vitamin A) to tissues. A recent report...
