RNA Epitranscriptomics and Proteomics Resource

RNA Epitranscriptomics and Proteomics Resource

The RNA Epitranscriptomics and Proteomics Resources (REPR) was created by consolidating the RNA analysis and proteomics capabilities existing at the University at Albany. This specialized resource offers an extensive range of state-of-the-art mass spectrometry instrumentation and know-how. The mission is to capitalize on the extensive expertise in the analysis of RNA, RNA modifications, and proteins involved in RNA metabolism/regulation to benefit both internal and external investigators interested in these types of topics.

The resource supports also projects involving the analysis of a wide range of biomolecules, metabolites, and small synthetic molecules. In addition to providing full-service analysis, REPR welcomes the opportunity to enter full-fledged partnerships that may involve extensive consulting on experimental design, sample preparation and data interpretation, as well as whole project development and grant writing contributions.

Frequently Asked Questions

Would it be possible to have one of my students/post-docs to learn how to perform analysis for us?

Yes, The resource offers five different platforms for self-service analysis:

  1. Agilent SQ single-quadrupole.
  2. Agilent QTOF quadrupole-time of flight.
  3. Sciext Q-Trap quadrupole-ion trap.
  4. Sciext Q-Star quadrupole-time of flight.
  5. Thermo LTQ-Orbitrap Velos.

You are invited to use the Service Selection app, which enables the selection of the desired platform and provides a possible cost estimate. Then email us at [email protected] to schedule proper training on the selected platform. After completing the training, you will receive a username and password to access the instrument scheduling system.

Is self-service analysis cheaper than full-service?

Yes, self-service analysis is cheaper than full-service analysis.
 

What are the terms for performing self-service analysis?

Use the Service Selection app to obtain an estimate of the costs for instrument time. Make sure to review the Instrument Usage Policies provided during training.

Do you work on samples submitted by companies?

Yes, the resource is set up to provide confidential service to private corporations. If required, we can sign material transfer agreements, non-disclosure agreements, and any other type of legal document. Email us at [email protected] with any questions you may have about this type of service.

Does REPR service only UAlbany Faculty?

No, REPR is open for business with any type of academic, government or private entity. Please email us at [email protected] if you have any questions about our services.

Is the service free for UAlbany Faculty?

No, The VPR’s Office and the Dean of Arts and Sciences fund the salary of REPR’s personnel, but instrument operations, upkeep, and consumables are paid by cost recharges. If you have financial constraints, there are different mechanisms at UAlbany to provide seed money to generate preliminary data for grant applications. If interested, please email us at [email protected].

What type of grant support does REPR provide?

The mission of REPR is to primarily support the research and scholarship of UAlbany Faculty, although collaborations with selected extramural investigators are also encouraged. Due to budget constraints, REPR prioritizes long-term relationships/projects over short-term service with no intellectual participation/commitment. To this effect, REPR is involved in project planning, generating preliminary data, helping with grant writing, and carrying out project activities after funding is secured. This type of involvement requires arrangements in which the pre-award REPR contributions are supported by startup, seed money, or other funding sources, whereas the post-award activities are covered by the grant’s budget. If you are interested in learning more about these types of arrangements, please email us at [email protected].

What type of help do you provide with data interpretation? How about pre-analysis planning?

The full-service option involves a modicum of help with experiment planning and data interpretation. If more time is necessary, REPR offers consulting services for very reasonable rates. Self-service analysis involves initial training, which is provided for a modest fee. During training, the instructor provides basic information on how to plan an experiment and perform data interpretation. Make sure to approach the training sessions with a specific project in mind, so that you can ask the most pertinent questions. If interested in learning more, use the Service Selection app to learn the going rates for consulting and training, or email us at [email protected].

Do you provide any type of sample preparation support at all?

Yes, we do, but on a limited basis. Due to personnel and budget constraints, we are limited on the type of operations that we can carry out, and on the number of samples that we can process. REPR encourages users to submit MS-ready samples, which can be readily analyzed by either direct infusion or LC-MS techniques. The Recommended Protocols provide a series of Standard Operating Procedures (SOPs) with instructions on how to best prepare the samples for immediate analysis. You can find the Recommended Protocols on the Services and Instrumentation tab.

If the desired type of sample is not covered, if you have questions on how to perform SOP procedures, or would like to know if REPR personnel can do sample preparation for you, please email us at [email protected].
