Neuropeptide Y (NPY) has been isolated and sequenced from brain extracts of the European common frog, Rana temporaria. Plasma desorption mass spectroscopy of the purified peptide indicated a molecular mass of 4243.3 Da which was in agreement with that deduced from the sequence (4243.7 Da), incorporating a C-terminal amide.
储存指南
一般情况下, Neuropeptide Y 粉末应该保存在-20甚至-70摄氏度. Neuropeptide Y 溶解后应该-70摄氏度分装保存,避免反复冻融. 了解更多细节,请查阅手册:多肽溶解及保存指南
