New ULS equipment - Refeyn Two Mass Photometer

The University Research Facility in Life Sciences (ULS) is pleased to announce that the Refeyn Two Mass Photometer is now available for booking. This new equipment applies light scattering-based technique to measure the molecular mass of biomacromolecules, e.g., proteins and DNAs, in their native state. It enables highly sensitive, rapid, and lable-free molecular mass measurement and is suitable for a wide range of applications, such as study of protein-protein interactions, determination of protein oligomerization states,  assessment of sample purity, etc.   If you have any queries about the Refeyn Two Mass Photometer, please do not hesitate to contact Dr So Pui-Kin or Dr Wang Chenyin of the ULS.   Thank you for your attention.

Updates on the ULS Equipment Charging Scheme and Payment Methods on URFMS

The University Research Facility in Life Sciences (ULS) will be updating our equipment charging scheme with effect from 8th April, 2024. Discounts will continue to be offered to internal research groups with monthly usage exceeding HK$5,000 (10% discount) or HK$10,000 (20% discount).   On the other hand, with immediate effect, users are encouraged to use real funding accounts (i.e., project accounts on PGMS) for equipment reservation. The current ULS virtual payment sources (i.e., ULS-DEPT-TAIMANCHAN-001) shall only be used as backup, in case the PGMS accounts and/or allocated balances have insufficient fund. Equipment reservation using PGMS funding accounts will be processed automatically via internal fund transfer, while that using virtual accounts will be billed monthly using invoices. For more details, please refer to our guidelines for internal users or supervisors.   If you have any queries, please do not hesitate to contact our staff.   Thank you for your attention.

Results for ULS Survey 2023

The University Research Facility in Life Sciences (ULS) has conducted surveys for users and PIs to evaluate the quality of service provided by the ULS in 2023. The surveys have ended last month and the reports are available via these links: Survey for Users, Survey for PIs. Note that in the last part of the reports you can find the ULS’s response to the respondents’ comments.   On the other hand, 20 survey participants were randomly selected to each receive 2 hours of free equipment usage for their laboratories in March. The result has been announced on the ULS Facebook Page.   If you have any queries about the survey, please do not hesitate to contact Dr Michael Yuen. Thank you for your attention.

ULS Training Session - The Refeyn Two Mass Photometer

The University Research Facility in Life Sciences (ULS) has just acquired a Refeyn Two Mass Photometer , which applies light scattering-based technique to measure the molecular mass of biomacromolecules, e.g., proteins and DNAs, in their native state. This equipment enables highly sensitive, rapid, and lable-free molecular mass measurement and is suitable for a wide range of applications, such as study of protein-protein interactions, determination of protein oligomerization states, assessment of sample purity, etc (refer to the attached brochure for more information).   There will be a hand-on training session(s) provided by the supplier on 27-Feb (Tue). We would like to invite TEN students/colleagues to join the training and each research group might assign ONE member to attend. One or multiple sessions in the morning and afternoon may be held, depending on the number of registered trainees.   Because of the hand-on nature of the training and lab space limitation, quota is limited to TEN and registration will be on first-come-first-served basis. If you are interested in attending the training, please provide me your name, department, and supervisor information and indicate your preference on morning/afternoon session by this Friday (23-Feb) noon.   Should you have any enquiries, please feel free to contact Dr. So Pui-Kin (Email: bckin@polyu.edu.hk, Tel: 34008797).
