摘要
We established a sensitive and specific two-site enzyme immunoassay (EIA) for prolactin-releasing peptide (PrRP) using two region-specific monoclonal antibodies. We investigated the tissue distribution and the plasma concentration of immunoreactive (ir-) PrRP in rats using this assay. Ir-PrRP was widely distributed in the central nervous system and pituitary gland. The highest concentration of ir-PrRP was found in the hypothalamus. In peripheral tissues, appreciable levels of ir-PrRP were found only in the adrenal gland. The mean plasma concentration of ir-PrRP was 0.13 +/- 0.01 fmol/ml (mean +/- SEM). In reverse-phase and gel-filtration high performance liquid chromatography, hypothalamic ir-PrRP eluted at a position identical to that of PrRP31 and PrRP20. On the other hand, ir-PrRP from the adrenal gland and plasma eluted only at the position of synthetic PrRP31, indicating that molecular forms of ir-PrRP in vivo differed among tissues.
