New ULS Equipment - Bruker Biospec 70/20 USR Magnetic Resonance Imaging System

The University Research Facility in Life Sciences (ULS) is pleased to announce that the Bruker Biospec 70/20 USR Magnetic Resonance Imaging System is now open to users.   The Bruker BioSpec 70/20 USR Magnetic Resonance Imaging (MRI) System is a state-of-the-art equipment for non-invasive preclinical imaging of small animals and tissue samples. The applications of the MRI system include diffusion tensor imaging (DTI), such as fibre tracking; functional MRI (fMRI), such as brain connectivity and optogenetics; MR spectroscopy (MRS), such as detection of metabolites, amino acids, lipids; angiography and cardiac imaging.     For arranging training or for other inquiries, please contact Dr Eva Lau or Dr Rachel Li.    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.

New ULS Equipment - Nikon AX R MP Upright Multiphoton Microscope

The University Research Facility in Life Sciences (ULS) has been supported by the Collaborative Research Fund (CRF) 2021/22 to acquire a Nikon AX R MP Upright Multiphoton (MP) Microscope.  The system is equipped with a dual-output pulsed laser for simultaneous multi-channel MP imaging and/or photostimulation, and supports high-speed intravital imaging using small animals. The system has been installed at the newly built Animal Imaging Centre (AIC) on Podium of Block Y and is now open for booking.   To introduce the major functions and applications of the new system, the ULS is going to hold a number of demonstration sessions on 5th and 12th July.  Online registration is now open until 2nd July.   Please contact Dr Michael Yuen for enquiries of the equipment or the demonstration.   Thank you for your attention.

Migration of PolyU ULS online booking system to URFMS (8)

ULS has kicked off the migration of the online booking system to University Research Facility Management System (URFMS, https://urfms.polyu.edu.hk/) since 2022. The migrated equipment list can be found in this link: https://www.polyu.edu.hk/uls/current-list-of-equipment-in-urfms/.   The last phase of migration includes the following equipment/software workstation:   Leica TCS SP8 MP multiphoton/confocal microscope Leica TCS SPE Confocal microscope Nikon Eclipse Ti2-E Live-cell Fluorescence imaging system Nikon NIS-Elements and MetaMorph image analysis software Leica LAS X image analysis software   We have helped to transfer user data (Equipment access) to the new system. Current users of the above equipment/software workstation can now log in the system and prepare for the URFMS online account. 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.
