Mass Spectrometry – MALDI-TOF
Equipment
MALDI-TOF-MS (Matrix Assisted Laser Desorption Ionization – Time Of Flight – Mass Spectrometry) Applied Biosystems Voyager DE-PRO Biospectrometry Workstation.

Sample
MALDI-TOF mass spectrometry is suitable for the analysis of biomolecules (peptides, proteins, polymers, organic molecules of high molecular weight, among others) though not limited to these.
For proper preparation of the samples, see the document - Sample preparation guidelines for MALDI
, and contact the technician in charge.

The applicant should directly contact the responsible for the equipment to clarify all the issues concerning the analysis. The equipment is operated only by the technician in charge. If requested it is permitted direct contact with the equipment along with a brief technical/theoretical description accompanied by practical demonstration of operation.

Delivery and reception of samples

  1. Samples must be properly identified indelibly and must be delivered properly packed.

  2. Samples from electrophoresis should be accompanied by a scan or photocopy of the gel image.

  3. The delivery of results will be made exclusively by e-mail in PDF format, sent simultaneously to the applicant and responsible.

  4. The remainder of the samples will be stored in the laboratory over a period of 15 working days after completion of the analysis, after which will be eliminated.
