ULS Newsletter (Fall 2019)

The second issue of the ULS newsletter has been issued. Please follow the link to view it online. The ULS newsletter aims at introducing the latest technologies and innovations in life science, promoting new and existing equipment managed by the ULS, as well as encouraging users and principal investigators to connect with us. We welcome readers to give us comments and suggestions as we strive to make our contents timely, relevant and interesting. Thank you very much for your support.

ULS Equipment Upgrade - Nikon N-SIM/N-STORM/A1 Super-resolution/Confocal Microscope

The University Research Facility in Life Sciences (ULS) is pleased to announce a major upgrade of the Nikon N-SIM/N-STORM/A1 Super-resolution/Confocal Microscope. In addition to featuring two super-resolution techniques (i.e., SIM and STORM) in one single system, the system is now equipped with a confocal scan head for performing laser scanning confocal microscopy, thus enabling researchers to perform correlative confocal-super-resolution imaging. Please refer to the ULS webpage for further details of the equipment, as well as for a sample image acquired in-house. For any enquiries on the equipment and for arranging for a training, please contact Dr Michael Yuen.

New ULS Equipment - Countess II FL Automatic Cell Counting and Imaging System

The Countess II FL Automatic Cell Counting and Imaging System will be available for booking in mid-July. The new system is capable of acquiring bright-field and fluorescence images of cell suspensions; and by automatic analysis of the images, allow researchers to instantaneously obtain such information as the cell count, labelling of fluorescent probes, expression of fluorescent proteins and cell viability, etc. Two training sessions have been arranged and the details are as follows: - Date: 16th July, 2019 (Tuesday) - Time: 3:30 to 4:15 pm (session 1); 4:30 to 5:15 pm (session 2) - Venue: Y709, Lee Shau Kee Building If you would like to sign up for the training, please email Dr Michael Yuen and provide your name, department, contact number and preferred session. Registrants will receive a confirmation email no later than 10th July.

ULS Seminar - ProteinSimple Capillary Western Blotting System

The University Research Facility in Life Sciences (ULS) is hosting a seminar on the ProteinSimple Capillary Western Blotting System. The details are as follows: Date: 5th July, 2019 (Friday) Time: 11:00 to 12:00 Venue: Y716, Lee Shau Kee Building (Block Y) Registration is not required for the seminar and demo, but seating will be on a first-come-first-served basis. Please contact Dr Michael Yuen if you have any queries.

New ULS Equipment - X-CLARITY Tissue Clearing System

The University Research Facility in Life Sciences (ULS) is pleased to announce that the Logos Biosystems X-CLARITY Tissue Clearing System is now available for booking. The new system comprises a polymerisation system for creating tissue-hydrogel hybrid constructs, and an electrophoretic tissue clearing system to remove lipids in the samples, making the latter largely transparent and thus suitable for 3-dimensional, deep-tissue imaging (e.g., using multiphoton or light sheet fluorescence microscopy). Please refer to Chung et al. (Nature 497, 332-337 (2013)) or the ULS webpage for further details of the technique, and contact Dr Michael Yuen for any enquiries on its applications and for arranging for a training.

Improve the Resolution and Contrast of your Confocal and Fluorescence Images by Image Deconvolution

The University Research Facility in Life Sciences (ULS) has recently upgraded our Imaris 3/4D image visualisation and analysis software to the latest version. In addition to 3D volumetric rendering and 3D colocalisation analysis, the version 9.3 now features image deconvolution, a commonly used image processing technique to improve both the resolution and contrast of images. For more details, please refer to the Imaris website or to sample images acquired in-house by the ULS. Please contact Dr Michael Yuen if you have any queries or if you would like to arrange for a training. Thank you for your attention.

New CPL spectrometer is now available for booking

The University Research Facility in Life Sciences (ULS) is pleased to announce that the JASCO CPL-300 Circularly Polarized Luminescence (CPL) Spectrophotometer is now available for booking. For details and charges of the instrument, and recent examples for its applications, please check the following link. Please contact Dr Carol Tsang (Email: carol.cs.tsang@polyu.edu.hk; Ext.: 8980) for any enquires on the application and training.

ULS training workshop: Circularly Polarized Luminescence (CPL) spectrometer

A training workshop for the JASCO CPL-300 Circularly Polarized Luminescence (CPL) spectrometer will be held on 25th April, 2019 in Y709. Two sessions are available for booking: Morning session : 10:00 am to 12:00 pm Afternoon session: 2:30 pm to 4:30 pm Due to space limitation, attendance of the workshop will be on a first-come, first-served basis. Please email Dr. Carol Tsang (carol.cs.tsang@polyu.edu.hk) with your contact information and preferred session for enrolment or for enquiry. For details of the instrument, please check the following link. For the fundamental and application of CPL, please check the following link.

New ULS Equipment - Nikon SMZ1270i Fluorescence Stereomicroscope

The University Research Facility in Life Sciences (ULS) is pleased to announce that the Nikon SMZ1270i Fluorescence Stereomicroscope is now available for booking. The new system is a parallel-optics and zooming type stereomicroscope offering advanced operability, as well as high magnification, zoom ratio and resolution. Please refer to the following link for details and charges of the instrument, and contact Dr Michael Yuen for any enquires on its applications and for arranging for a training.
