Since ResearchGate discontinued the project logs, we moved it to our very own website of MALDI-UP. The project log will show you updates about new entries in the MALDI-UP catalogue available for exchange as well as news about protocols or events like the MALDI workshop. Moreover we will send the newest log entry via email to those who are pleased to get the news directly into their mail box. You can cancel your subscription at any time.
