Our Lab got a new device! Yesterday, we exchanged our toy FPLC (thanks for reserving the bench space) for the real thing: a brand new ÄKTA Go for use in our protein production and purification workflows, as well as for analytical projects. Big thanks to Cytiva for setting up and testing the system.

The downside of remote work is that some of us do not meet very often. On the plus side: having everyone in the office at the same time is an occasion to celebrate! 🎉 Here we are enjoying a Bavarian "Weißwurst Frühstück" while connecting with colleagues, having inspring discussions and a great day!

Quantify your #GFP-labeled proteins with our 15N-labeled GFP reference standard. Also for proteins that are difficult to quantify using #massspectrometry (few tryptic peptides, low signal intensity, etc.), GFP tagging may be the solution. Need more information or a quote? www.polyquant.de/contact
