Somatostatin [SST, GHIH (growth hormone-inhibiting hormone) or SRIF (somatotropin release-inhibiting factor)] is a cyclic peptide existing in two isoforms and is produced in the pancreas islet, GI tract and the central nervous system. Tetradecapeptide Somatostatin-14 (SRIF-14, the originally identified somatostatin) and the 28-amino acid Somatostatin-28 (SRIF-28) have similar biological activities but differ in their potency. Somatostatins inhibit the release of growth hormone in contrast to Growth Hormone Factor (GRF), which stimulates the release of growth hormone. Somatostatins also inhibit the release of prolactin and thyrotropin, peptide hormones from the pituitary gland and glucagon and insulin from the pancreas. It also controls the secretion of gut hormones and functions as a neurotransmitter. | |

帮帮忙,谢谢
现在对美国perkinelmer公司和德国berthold公司的产品有兴趣,
perkinelmer公司的样品形式可选用6,12,24.........384空板进样同时检测,比较方便。检测灵敏度为3attomoleATP;
berthold公司的样品形式只有试管单管进样,比较麻烦;但是检测灵敏度为1attomoleATP,灵敏度更高。
请教前辈我该如何选择?请问一般荧光素酶报告基因发光值一般是什么数量级?
MPI是一种基于消息传递的并行编程技术,在不同节点计算机之间并行多进程执行程序(这种情况下,不同享内存),只是通过消息传递来进行通信,从而适用于分布式体系
是将具有高灵敏度的化学发光测定技术与高特异性的免疫反应相结合,用于各种抗原、半抗原、抗体、激素、酶、脂肪酸、维生素和药物等的检测分析技术。是继放免分析、酶免分析、荧光免疫分析和时间分辨荧光免疫分析之后发展起来的一项最新免疫测定技术。
