Mass spec analysis service: Switching paper form to electronic form

To reduce paper consumption and conserve natural resources, we are going to launch the use of electronic sample submission form (download here) instead of the paper submission form for the mass spectrometry analysis service. From now on, users can submit the form via email to Dr. So Pui-Kin and Dr. Carol Tsang upon submitting samples to the Mass Spec lab (W711). For more details about sample submission, please read the guidelines listed on the form.     You can contact Dr. So Pui-Kin (bckin@polyu.edu.hk; ext. 8797) or Dr. Carol Tsang (carol.cs.tsang@polyu.edu.hk; ext. 8980) for any inquires on the mass spectrometry analysis service.  

SkyScan 1276 microCT: Technical basics and working procedure

Bruker SkyScan 1276 in vivo microCT scanner has been recently installed in the ULS. This system allows continuously variable magnification scanning and 3D reconstruction of small laboratory animals as well as biological samples or other materials with high spatial resolution down to 2.8 µm pixel size. For more information about the equipment, please visit here.   This seminar will cover the microCT system introduction, sample preparation and parameter settings, scanning modes and applications.   Title: SkyScan 1276 microCT: Technical basics and working procedure Date: 25 Oct 2021 (Monday) Time: 10:00 a.m. - 12:00 p.m. Speaker: Dr. Wong Rui (Application Specialist from Bruker (Beijing) Scientific Technology Co., Ltd) Venue: Online via Microsoft Teams     Please click HERE for registration (Link for online seminar will be sent to registered users by email later)   Should you have any enquiries, please contact Dr. Rachel Li (email: rachel.ws.li@polyu.edu.hk)

ULS Seminar - Surface Plasmon Resonance System

The University Research Facility in Life Sciences (ULS) is co-organizing an online seminar on the Surface Plasmon Resonance (SPR) System with Cytiva. SPR is a label-free spectroscopic technique for studying molecular interactions (binding affinities, association/dissociation kinetics) in real-time using relatively small quantities of materials (organic compounds, nucleic acid, glycoproteins, viruses, etc.). This technology is not only valuable in the fundamental understanding of biological processes but also in drug discovery. For more information about the technology, please visit the website of Cytiva. The details of the upcoming seminar are as follow: Date: 8th October 2021 (Friday) Time: 10:00 – 11:30 am Speaker: Michael Luo, Advanced Product Specialist, Cytiva Rundown: (1) Introduction on the Biacore SPR system; (2) Application on studying molecular interaction of protein, organic compounds, nanoparticles, etc, for the understanding of biological processes and drug screening If you are interested in attending this online seminar, please complete the online registration form by 7th October 2021. Successful registrants will receive a confirmation email and the Microsoft Team meeting link one working day before the event. For any inquires on the seminar, please contact Dr. Carol Tsang. Thank you for your attention.

New ULS Equipment - Cytiva AKTA pure 25 M1

The University Research Facility in Life Sciences (ULS) is pleased to announce that the Cytiva AKTA pure 25 M1 for purification of proteins, peptides, and nucleic acids is now available for booking. The system allows flexibility in purification of proteins, peptides and nucleic acids by different chromatography techniques, including ion exchange chromatography, affinity chromatography and gel exclusion chromatography, etc. Please refer to the following Equipment Page for details and charges of the instrument and contact Dr Ryan Chow for any enquiries on its applications and for arranging a training. Thank you for your attention.

ULS Online Seminar - Igniting New Insights with CyTOF

Mass cytometry, or Cytometry by Time-Of-Flight (CyTOF), is a powerful platform for high-dimensional profiling of cell phenotypes and signalling pathways at single cell resolution. In this seminar, the technology of Mass Cytometry for cells in suspension and Imaging Mass Cytometry for Cellular Tissues, the workflow and its capabilities in the context of deep immune profiling and applications into tissue immune microenvironment will be discussed. Title: Igniting New Insights with CyTOF® - with Highly Multiplex Mass Cytometry and Imaging Mass Cytometry Date: 28 July 2021 (Wednesday) Time: 2:30pm - 4:00pm Speaker: Dr. TEH Boon-Eng (Senior Manager - Service and Support; Fluidigm Greater Asia) Venue: Online via ZOOM Please click HERE for registration (Link for online seminar will be sent to registered users by email later) Should you have any enquiries, please contact Dr. Rachel Li (email: rachel.ws.li@polyu.edu.hk). Thank you for your attention.

ULS Equipment Upgrade - FACSAria III

We are glad to announce that the 5-lasers FACSAriaIII cell sorter in ULS has recently been upgraded with an Automatic Cell Deposition Unit (ACDU) which users can perform single cell sorting or index sorting into 6, 24, 48, 96, and 384-well plates. It is an important additional tool for subsequent single cell analysis. For more information or training session of this accessory, please do not hesitate to contact Dr. Ryan Chow (34008057) or Dr. Rachel Li (34008056) for arrangement.
