在三个Ca2+离子的作用下，水母发光蛋白分子将腔肠素-h底物氧化为腔肠酰胺，释放二氧化碳并在469nm处产生具有峰值的闪光，通过VICTOR Nivo检测。由于GPCR激活后细胞内Ca2+浓度增加且相应的闪光产生速度非常快，因此该检测需要极快速的测量响应。VICTOR Nivo读板仪的分液器可以满足这一需求，它可以在进样后0.1秒从微孔...
中国地质大学通过扩散法制备了高度Ca2+交联的醛藻酸-明胶亚胺基(CaAG)水凝胶(图1a-c)。相关结果以“role of a high calcium ion content in extending the properties of alginate dual-crosslinked hydrogels”为题发表在期刊《Journal of Materials Chemistry A》。水凝胶为酒红色,随着孵育时间的增加颜色变深(图1d...
For the functional analysis of ion channel activity, an artificial lipid bilayer suspended over microwells was formed that ruptured giant unilamellar vesicles on a Si substrate. Ca(2+) ion indicators (fluo-4) were confined in the microwells by sealing the microwells with a lipid bilayer. An over...
既往有研究报道过腺相关病毒介导心肌肌浆网(Ca2+ -ATPase 2a, sarcoplasmic reticulum Ca2+ -ATPase,SERCA2a)基因转导治疗大鼠慢性心力衰竭。 发表在2021年8月《循环》杂志的一篇基础研究假设MYDGF参与了心脏对压力超负荷诱导心力衰竭的适应性...
To ascertain the role of Ca2 þ in photoreceptor degeneration caused by loss of Pde6, it is necessary to measure this ion within the inner segment. We therefore generated here a double-transgenic zebrafish, transgenic (Tg; Tr2:tdTomato; TaCP:GCaMP3), in which the Ca2 þ indicator GCa...
Lu- Yang Wang3 & Jiuping Ding1 Ca2+ ions play crucial roles in mediating physiological and pathophysiological processes, yet Ca2+ dynamics local to the Ca2+ source, either from influx via calcium permeable ion channels on plasmic membrane or release from internal Ca2+ stores, is difficult ...
b STRING analyses of upregulated (not downregulated) genes in the NRXN1α+/− neurons showed association with “calcium ion transport” (red, 12 genes, FDR + 3.20E−03), “calcium ion transmembrane transport” (blue, 9 genes, FDR = 2.06E−02), “voltage-gated calcium ...

Fluo-5N and rhod-5N dyes were excited with a 488 nm Ar-ion laser and 543 nm HeNe laser, respectively, and the emission was filtered using the Olympus spectra detector. In 3D imaging for reconstructing the fibre structure, the pinhole was adjusted to 0.7 airy units and each confocal section...
