Peptide Core

蛋白质化学和肽合成一直是该方案活动的一个突出特点 自1968年成立以来。最初，这些活动是作为一个组成项目的一部分进行的， 甲状旁腺素和降钙素的结构分析和构效关系研究。除了 最早的活性合成钙调节肽，对测序的基础和持久贡献 和合成方法从这些调查中出现。这些化学品的多功能性日益增加， 这些方法为所有项目带来了稳步扩大的利益;为了满足由此产生的需求， Core成立于1979年。除了继续开发合成PTH激动剂和 拮抗剂，核心继续履行这样的不同作用，如鉴定体内PTH代谢的产物， 用于一系列生物学和免疫学测定、表征和微测序的校准标准品 重组表达产物和生物合成标记的蛋白质，以及表征膜蛋白 与成功纯化PTH/PTHrP受体的努力相结合。 随着20世纪80年代中期内分泌单位迁入韦尔曼（现为他们的）大楼实验室 这是资源共享过程中的第一步，一直持续到今天，给双方带来了重大利益。 项目和NIH。1993年正式合并为一个共同的分析综合设施， 分子内分泌学和生殖内分泌单位，其次是艾滋病研究伙伴 中心，核心获得了重要的新功能，包括气相测序，微孔HPLC和 提高综合能力。当时和现在一样，运营成本在个人之间仔细分配， 根据利用情况，项目和调查员的人数减少，但扩大获得信息的机会所实现的效益减少， 方法、经验的深度、人员部署的灵活性和规模经济， 在最后一次计划项目更新时明显。

Protein chemistry and peptide synthesis have been a prominent feature of the Program's activities since its inception in 1968. Originally, these were carried out as a part of a component Project aimed at the structural analysis and study of the structure-activity relations of parathyroid hormone and calcitonin. Besides the earliest active synthetic calcium-regulating peptides, fundamental and enduring contributions to sequencing and synthetic methodologies emerged from these investigations. The increasing versatility of these chemical methods brought steadily expanding benefits to all of the projects; to meet the resulting needs, a separate Core was established in 1979. In addition to continued development of synthetic PTH agonists and antagonists, the Core proceeded to fulfill such diverse roles as identifying products of in vivo PTH metabolism, calibrating standards for a range of biological and immunological assays, characterizing and microsequencing recombinant expression products and biosynthetically labeled proteins, and characterizing membrane proteins in conjunction with the successful effort to purify the PTH/PTHrP receptor. With the move of the Endocrine Unit into the Wellman (now Their) Building laboratory in the mid-1980's came the first step in the process of resource sharing that continues to this day to bring major benefits to both the Program and the NIH. By formally consolidating in 1993 into a common analytical-synthesis facility with the Molecular Endocrinology and Reproductive Endocrine Units, followed by the Partners AIDS Research Center, the Core gained important new capabilities including gas-phase sequencing, microbore HPLC and enhanced synthesis capacity. Then, as now, operating costs were carefully allocated among the individual projects and investigators according to utilization, but the benefits realized from widened access to methodology, depth of experience, flexibility in personnel deployment and economies of scale were clearly apparent at the time of the last Program Project renewal.
