background: in the recent years, there has been an increasing interest in secretory production of recombinant proteins, due to its various advantages compared with intracellular expression. signal peptides play a critical role in prosperous secretion of recombinant proteins. accordingly, different signal peptides have been assessed for their ability to produce secretory proteins by trial-and-er...

Immunoglobin A in bile and other external secretions is mostly bound to a glycoprotein known as secretory component. This glycoprotein is not synthesized by the same cells as immunoglobulin A and is not found in blood. We now report the mechanism by which secretory component reaches the bile and describe its function in immunoglobulin A transport across the hepatocyte. Fractionation of rat live...

It is very important to validate the characterization of medicinal plants ensure their use, especially if are be used only for certain organs. This study aimed obtain information related type secretory structure and secondary metabolites they accumulated, as well phytochemical profile three antihypercholesterolemic plants. organs (leaves, stem bark, roots) from Moringa oleifera, Muntingia calab...
