CRH Antibody Staining Protocol for Immunohistochemistry


Description: CRH is a 41-amino acid peptide derived by enzymatic cleavage from a 191-amino acid preprohormone and is located on 8q13. It is made not only in the hypothalamus but also in peripheral tissues, such as T lymphocytes, and is expressed in very large amounts in the human placenta. As a placental clock, CRH controls the duration of pregnancy and that the timing of the rise in CRH may permit prediction of the onset of labor. Furthermore, CRH is the most proximal element of the HPA axis, and it acts as a central coordinator for neuroendocrine and behavioral responses to stress. In addition, placental secretion of CRH is a marker of the 'placental clock' that is active from an early stage in human pregnancy and determines the length of gestation and the timing of parturition and delivery.
