New ULS Equipment - ThermoFisher Glacios 200 kV Cryo-electron Microscope

The University Research Facility in Life Sciences (ULS) is excited to announce that the ThermoFisher Glacios 200 kV Cryo-electron Microscope (Cryo-EM) is open to users. The Glacios system is equipped with the latest Falcon 4i direct electron detector, which delivers higher image quality and shorter total image acquisition time than previous models. The system is an essential piece of equipment for the whole cryo-EM workflow, as it allows researchers to verify sample quality with regard to the biochemistry and vitrification. Applications of the Glacios system include single-particle analysis (SPA), micro-electron diffraction (MicroED), and cryo-electron tomography (cryo-ET) workflows.   In addition, two sets of ThermoFisher Vitrobot Plunge-freezing Systems are also available to support sample vitrification for subsequent cryo-EM and cryo-ET workflows.   If you have any inquiries about the Glacios 200 kV Cryo-EM or the Vitrobot Plunge-freezing Systems, please do not hesitate to contact Mr Sirui Li or Dr Harvey Chan of the ULS.   Thank you for your attention.

New ULS Equipment - Zeiss Lattice Lightsheet 7 Microscope

The University Research Facility in Life Sciences (ULS) is pleased to announce that the Zeiss Lattice Lightsheet 7 (LLS7) Microscope is now open to users. The technique uses optical lattices to create ultrathin laser lightsheet to improve axial resolution and has since proved to be a power tool for live imaging. The LLS7 system has a specially designed inverted configuration that allows researchers to use common sample carriers and is equipped with 2 scientific-grade CMOS cameras for simultaneous dual-channel imaging at speed up to 3 volume scans per second.   To introduce the major functions and applications of the LLS7 system, the ULS is going to hold a number of demonstration sessions on 9th August, 2023.  Online registration is now open until 3rd August, 2023.   Please contact Dr Michael Yuen for enquiries of the equipment or the demonstration.   Thank you for your attention.

New ULS Equipment - ThermoFisher Talos L120C Transmission Electron Microscope

The University Research Facility in Life Sciences (ULS) is pleased to announce that the ThermoFisher Talos L120C Transmission Electron Microscope (TEM) is now available for booking. The new system has been installed in the ULS Cryo-EM Centre, and is mainly used for sample screening and data collection using negatively stained biological specimens. The enhanced contrast of negative stain EM allows preliminary examination of relatively small biological samples with sizes under 30 nm, such as protein particles. The Talos L120C will enable researchers to acquire high-quality images with simple and intuitive image acquisition software.   If you have any queries about the Talos L120C TEM System, please do not hesitate to contact Mr Sirui Li or Dr Michael Yuen of the ULS.   Thank you for your attention.

Once completed simple registration procedures, online booking of the above equipment/software workstation can then be made immediately for any date on or after 30th June 2023 (Friday). Attached the guideline for user and supervisor, respectively.   User Guide-ULS-July.pdf User Guide for Supervisor.pdf   Below are some highlights of the migration: •        New URFMS user needs to log in the system, agree the Terms and Conditions, add an emergence contact number and seek endorsement from supervisor through the system. •        Virtual ULS payment account is used for booking instead of a true research funding account, usage cost will be included in the current ULS monthly invoice. The virtual ULS payment account and invoice payment method is only applicable to the ULS system. •        Supervisor needs to approve user registration in the URFMS and agree the Terms and Conditions. Budget allocation and budget top-up is not needed. •        Supervisor can grant right to a team member to use the virtual ULS payment account.   If you have any queries, please do not hesitate to contact Dr. Ryan Chow at 34008057 or hoyin.chow@polyu.edu.hk.
