93318 - Bioanalytical Proteomics and Interactomics

Academic Year 2021/2022

  • Teaching Mode: Traditional lectures
  • Campus: Bologna
  • Corso: Second cycle degree programme (LM) in Bioinformatics (cod. 8020)

Learning outcomes

At the end of the course, the student has the basic knowledge about analytical methods and in silico tools for qualitative and quantitative proteomic analysis, in particular dealing with soft impact mass spectrometry technologies and proteins/peptides analysis in complex biological matrices. The student will also acquire fundamental skills about experimental and computational approaches used for interactomics. In addition, the student will be able to select the most suitable analytical technique to solve a given analytical problem dealing with proteomics and to critically evaluate the analytical result.

Course contents

Introduction to proteomics: structural and functional proteomics, strategies for proteomic analysis.

Separative techniques in proteomics: gel electrophoresis (SDS PAGE, 2D PAGE), non-denaturing gel electrophoresis, capillary electrophoresis, HPLC (reverse phase, ion exchange, size exclusion), multidimensional HPLC.

Mass spectrometry techniques in proteomics: soft ionization techniques, MALDI and ESI ionization sources, quadrupole mass analyzers, time-of-flight mass analyzers (TOF), hybrid analyzers (Q-TOF), mass spectrometers (MALDI/TOF and ESI/Q-TOF), SELDI/TOF analysis.

Protein identification: analysis of intact proteins by ESI/MS and MALDI/MS, in-gel digestion, in-gel digest analysis by MALDI/MS and ESI/MS, database search for protein identification.

Applications of proteomics: proteomics in clinical analysis, “shotgun” proteomics, peptide fingerprint mapping, study of protein complexes, studio di complessi proteici, detection and identification of post-transcriptional protein modifications.

Interactomics: experimental (Two hybrid systems, FRET, BRET, phage display, microarrays, biosensors) and bioinformatic approaches to predict protein funtion and protein-protein interactions.

Luminescence Molecular Imaging: localization and quantification of analytes in single cells and tissue (combined with microscopy), whole organ and living organisms using nanoparticles and recombinant bioluminescent cells.

In silico cloning and mutagenesis of recombinant proteins.


Scientific publications will be provided during the course.

Teaching methods

The course consists both in lectures dealing about the topics listed in the program and a series of in silico labs (experiments and/or demonstrations concerning common proteomics procedures and applications).

Assessment methods

At the end of the course oral examination will take place to ascertain the acquisition of the learning outcomes of the course:

- basic knowledge in proteomics (soft impact mass spectrometry technologies and smart sample handling for proteins /peptides quantitative analysis and identification in complex biological matrices).

-knowledge about interactomics strategies (both experimental and bioinformatics tools)

-knowledge about methods based on molecular recognition combined with selective and highly detectable probes and luminescence molecular imaging

Oral exam has an average duration of 20 minutes and consists of 3 questions on the topics of the course. Final score is the average of the marks obtained by the student in the separate questions.

Note: assessment methods could vary in case of extension of the anti-COVID measures. Students will be promptly informed by the  teacher in case of variation.

Teaching tools

Video and overhead projector. Slides of all the lectures are available as PowerPoint files.

Power point presentations used during the lessons and any research material will be provided to the students in electronic format via Internet. The power point presentations used during the course will be uploaded on the site Insegnamenti on line [https://iol.unibo.it/] before the corresponding lesson. It is advisable to consult the ppt presentations before the lesson in order to be able to follow the lesson in a proactive way. It is suggested to download (or print) presentations and bring them to class in order to integrate them with notes.

Possible distance teaching will be given through Microsoft Teams with the support of Microsoft 365 software suite.
