rGHRH(1-29)NH2是能刺激生长激素(GH)分泌的合成肽。
Sample solution is provided at 25 µL, 10mM.
rGHRH(1-29)NH2 is a synthetic peptide which can stimulate the growth hormone (GH) secretion.
Time course studies of rGRF(1-29)NH2 disappearance show apparent half-lives of 18±4 min and 13±3 min in serum and liver homogenate, respectively. This is accompanied by the appearance of degradation products that are all less hydrophobic than the native peptide. In the serum, two major metabolites are detected and isolated by preparative HPLC[1].

Cell experiment: | To isolate GRF metabolites in the liver, rGRF(1-29)NH2 (10 mg) is first preincubated in 232 mL of Krebs' buffer (5 min, 37°C) to help GRF solubilization and then incubated with a liver homogenate in a shaking bath at 37°C. The homogenate is prepared as in the degradation assays with 580 mg of liver (10 mg/mL). The reaction is stopped after 30 min by adding 174 mL of cold 50 mM phosphate solution (pH 0.8) and centrifugation (48,000×g, 20 min, 4°C). The supernatant is filtered twice and its pH is adjusted (3.0) with 6 N NaOH before chromatography. The GRF metabolites and residual rGRF(1-29)NH2 are isolated[1]. |
