Maurice iCE Instrument runs capillary electrophoresis sodium dodecyl sulfate (CE-SDS)

One CE-SDS Instrument, Seamless Method Transfer

Both Maurice and MauriceFlex allow you to use a single instrument for both Turbo CE-SDS and CE-SDS PLUS assays. Method development is effortless, and the data is 21CFR Part 11 compliant, ensuring a smooth transition between stages of biotherapeutic development.


CE-SDS for all Stages of Biotherapeutic Development

Turbo CE-SDS™ - Achieve rapid size analysis in just 5.5 minutes per sample, ideal for early discovery, clone selection, and formulation studies.
CE-SDS PLUS - Fast method development, superior resolution data, and seamless method transfer for analytical development and QC.

Choosing CE-SDS Over SDS-PAGE

Say goodbye to cumbersome and manual SDS-PAGE – no more preparing gels, laborious sample prep, and poor reproducibility. With CE-SDS, you’ll get high quality, quantitative, and reproducible data. You can even get a gel-like representation of your data using Lane View on the Compass for iCE software. Maurice even comes with an optional filtration upgrade for containing those noxious β-ME odors.
