Publication number: 20210208088Abstract: The present invention relates to a magnetic holder for immunoelectron microscopy grids. The holder comprises a frame, a magnet and a hydrophobic layer. The device can use a magnetic force to simultaneously attach the outer rings of nickel grids to the frame, so that a batch operation (such as rinsing, immunolabeling and dyeing) of the nickel grids can be realized. In addition, due to the hydrophobic effect of the hydrophobic layer, the holder can reduce the amount of the liquid carried by the nickel grids in the process of continuously transferring the nickel grids between different types of liquids to almost zero. Compared with the prior art, the magnetic holder effectively reduces the probability of cross-contamination between reagents.Type: ApplicationFiled: January 2, 2021Publication date: July 8, 2021Applicant: Institute of Microbiology, Chinese Academy of SciencesInventors: Jingnan Liang, Yiwei Liu, Qian Wang, Zhousinuo Jiang, Xing Dai, Hao Liang, Yuanming Luo, Chunli Li, Zheng Fan, Tong Zhao, Shutao Sun, Xiaolan Zhang
