Advantages of CE-SDS over SDS-PAGE
SDS-PAGE is widely used for protein purity analysis but is only semi-quantitative and is limited by challenges like tedious sample prep and poor reproducibility. It then becomes difficult to precisely assess the product's efficacy and/or safety, potentially delaying, even jeopardizing, its approval. In contrast, CE-SDS is a highly quantitative method for purity analysis that gives you high-quality, reproducible data. Other advantages of CE-SDS on Maurice include:
- Automation
- Ease-of-use
- Increased throughput
- Fast turnaround time
- Streamlined workflow
Listen to our podcast with Drug Discovery World (DDW) and Dr. Tufan Aydogdu, Field Applications Scientist, ProteinSimple, a Bio-Techne brand, where they dive into the details of automated CE-SDS and the advantages it brings over SDS-PAGE.
Transition from SDS-PAGE to CE-SDS
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.
Here are some more resources to help you with your transition:

One Instrument for All Your CE-SDS Needs
Whether you're in early discovery or late-stage QC, use one instrument for your CE-SDS methods to save on time, capital, and bench space. Turbo CE-SDS and CE-SDS PLUS cartridges are specifically designed to address your stage-specific CE-SDS needs. Turbo CE-SDS gives you speed and throughput ideal for early development and formulation, while CE-SDS PLUS has the resolution you need for analytical development and QC. Switching between the two is simply a matter of swapping out the cartridges. Method development is fast and easy, method transfer is seamless—even between cartridges—and the data is 21CFR Part 11 compliant.
Turbo CE-SDS™
The Turbo CE-SDS cartridge gives you high throughput with analysis in as little as 5.5 minutes per sample, without any protein labeling. Prepare you samples, plug in the cartridge, load them onto your Maurice instrument, and get high quality data with direct detection. Ideal for use in early discovery, clone selection, and formulation stability studies, where sample throughput is the biggest bottleneck.
CE-SDS PLUS
The CE-SDS PLUS cartridge lets you develop your methods fast, transfer them easily across phases, and gives you superior resolution data, all within 25-35 minutes. Best for use in analytical development and QC.
