Join us for this webcast to learn about tools for micro- and nano-scale HPLC that are now available, in terms of new column technologies, injection modes (trap and elute), and separation condition strategies, and even connection systems that can help with the miniaturization of analytical scale separations to micro and nano scale. ***On demand available after final airing until Nov. 12, 2021***

IdeS, a cysteine protease, is used for partial digestion of mAbs and generates a (Fab’)2 fragment and two Fc fragments (Fc/2) for better characterization of the Fc fragment.

This application combines cysteine proteases IgdE and IdeS, to observe conserved and hypervariable regions of the antibody, as well as identification of other variants.

IgdE allows for better characterization of the antibody and yields an intact Fc and an intact Fab fragment that can be further isolated and characterized.

Comparing core-shell superficially porous to fully porous particles to determine efficiency required for detection, separation of low-level impurities for subunit analysis.

A reversed-phase method using a superficially porous, wide pore particle morphology for the quantitation of coformulated mAbs leads to high efficiency separations.

For LC–MS analysis of NIST mAb, multiple C4 LC columns are compared to determine which provides necessary separation of impurity and avoids spectral overlap in the MS detector.

For Fc Fusion proteins a reversed-phase LC analytical method is used for either extended characterization and identification for impurities or as a simple purity method.
