Preparation and characterization of a novel recombinant human parathyroid hormone (1-34) analog (Gly1-Gln26-rhPTH(1-34)) with enhanced biological activity.

abstract：:Though protein folding is a regular phenomenon inside the cellular milieu, slight differences in the folding pattern of proteins may lead to disease-causing forms. Many diseases have been identified that are caused by these misfolded macromolecules and a considerable amount of focus is still directed towards better un...
