Collaborating across Europe:

Arda’s secondment at ITQB NOVA

Collaboration is key in the EvaMobs project, bringing together expertise from partners across Europe to build the innovative EvaMobs platform. While much of this teamwork happens remotely – bridging institutes and countries – some knowledge simply travels best in person.

When it comes to sharing hands-on lab techniques to optimise our monobody formulations, face-to-face collaboration is essential. That’s why recently, Arda Deniz Tugrul, PhD candidate at NIBRT (UCD) in Dublin travelled to ITQB NOVA for a six-week secondment, to collaborate on improving the stability of monobodies and preventing aggregation (the joining and clustering together of monobodies). He explains:

“The purpose of my visit to ITQB NOVA was to collaborate on this project by studying monobody stability and exploring protein modifications aimed at reducing this aggregation.”

Looking ahead, Arda is preparing to consolidate the findings from his visit: “My next steps involve summarising the work accomplished during the secondment and continuing with formulation screening studies on monobodies.”

“I am very grateful for the support and collaboration I received from ITQB NOVA during my secondment and look forward to continuing our work together in the future.”

Maja Katalinić

Scientific Advisor

Maja Katalinić, PhD, has 20 years of experience in the field of drug discovery research and excellent insight into its high demands. She possesses invaluable experience in enzyme kinetics and enzyme biochemistry in general, as well as in evaluating drugs’ effects on the cell level in the early phase of studies. She has passed several trainings in molecular biology as well as training for lab management/leadership. She was a leader and collaborator on national and international projects involving research on antidotes development for the treatment of organophosphorus compounds poisoning, while in 2017 she establish her research group focusing on the molecular mechanisms underlying the toxicity of antidotes and potential drugs. As a leading researcher of IMI team, Dr Katalinić will be responsible for the overall implementation of cell-based in vitro toxicology assays as a safety assessment to evaluate Mobs toxicity.

João B. Vicente

Auxiliary Investigator

João has a background in protein biochemistry and biophysics, with research dedicated to investigating the molecular mechanisms of proteins related to human disease. He leads the APB lab at ITQB NOVA, which specializes in the production of recombinant proteins and their functional and structural characterization using biophysical methods.

In EvaMobs, the APB lab is responsible for bringing the computationally designed Mobs to life. The lab has been implementing screening approaches based on small-scale Mobs production and purification, followed by analysis of thermal stability and binding affinity. Selected hit Mobs are then produced on a larger scale, their biophysical and functional properties analyzed, and sent to consortium partners for further evaluation in other work packages.
