Accelerating GLP-1 Analog Impurity Profiling with the Agilent Pro IQ Plus Followed by Detailed Sequence Analysis using Electron Capture Dissociation
In biotherapeutic development, speed and confidence in impurity profiling are critical to moving candidates forward. This webinar introduces a streamlined workflow designed to accelerate impurity profiling of GLP-1 analogs. It begins with impurity screening using the new Pro IQ Plus single quadrupole mass detector. Then, detailed sequence analysis is performed using the 6545XT AdvanceBio LC/Q-TOF, equipped with an ExD cell to enable electron capture dissociation (ECD). ECD offers a gentler fragmentation approach than traditional CID, preserving labile modifications and enabling detailed structural insights.
We highlight key advantages of ECD including modification localization, isoaspartate investigation, and discuss the importance of spectral quality in sequence confirmation. Whether you're optimizing GLP-1 analogs or exploring new biotherapeutics, this webinar highlights how Agilent’s tools can help get answers faster and go deeper with your data.
