Expression and purification of recombinant vesicular glutamate transporter VGLUT1 using PC12 cells and High Five insect cells

In synaptic vesicles, the estimated concentration of the excitatory amino acid glutamate is 100–150 mM. It was recently discovered that VGLUT1, previously characterized as an inorganic phosphate transporter (BNPI) with 9–11 predicted

TEM 操作图解：一文读懂外泌体鉴定，学霸入门必备

的？声明：本次操作基于我司最近正在使用的 HT7700；1、送样要求：样品尽可能浓，颗粒浓度 1.0E+10；2、拍摄规范：样品以茶托状（有明显凹陷的）球形，椭球形或扁圆形，尺寸在 30-150nm，有双层膜结构的颗粒为目标进行拍摄；照片以轮廓清晰，分辨率高，焦距合适（既没有过焦的虚影，也没有欠焦的黑边），背景杂质少，明暗适宜，颗粒居中，整体美观为佳；默认拍摄 100nm 一张，200nm 三张，500nm 一张；注：铜网中样品焦距无法调清时以调试后的最佳结果拍摄，样品中无特征明显的颗粒或无颗粒时
