Reproducible Intact Protein Analysis: The Right Technology for Your Lab
Intact biotherapeutic analysis is used throughout the product development life cycle to ensure both the proper selection of lead candidates and reproducible product quality. However intact protein characterization of diverse and complex biotherapeutics can be extremely challenging, presenting several analytical performance issues.
SCIEX offers a range of technology solutions specifically designed to address the analytical challenges of intact protein analysis, from candidate selection to post-commercialization. Our innovative LC-MS, CESI-MS and capillary electrophoresis (CE) technologies consistently deliver fast, accurate and reproducible assays and easy to interpret analysis for diverse and complex biotherapeutics.
Solving the Challenges
Your increasing workload means you need highly reproducible intact protein data at your fingertips. SCIEX offers multiple approaches that enable you to routinely analyze even the most complex biotherapeutics throughout the development life cycle. Our powerful LC-MS, CESI-MS and CE technologies provide you with high quality, highly reproducible intact protein characterization data, faster and more efficiently than you thought possible.
“…characterization of biomolecules by CE is a robust technology when the method is well described and controlled. This exercise supports and endorses the increased application of CE methodology within both development and QC laboratories within biopharmaceutical companies.” - Intercompany collaboration on CE-SDS: A Series of Collaborations Between Various Pharmaceutical Companies and Regulatory Authorities Concerning the Analysis of Biomolecules Using Capillary Electrophoresis, Chromatographia 2006, 64, 359–368, B.

Robust and Reproducible Solutions for Intact Characterization
Intact protein analysis is required throughout the drug development pipeline from clone selection to post-commercialization. Whether you need to confirm your protein mass, analyze protein charge variants or execute routine standardized assays in a compliant environment, SCIEX has a tailored solution to meet your needs.
Simplified and Accelerated Accurate Mass Analysis by LC-MS
Intact mass and subunit analysis by LC-MS provides confirmation of therapeutic mass and high-level heterogeneity. You can accelerate your routine intact and subunit biologic protein workflows with the ultra-compact and user friendly X500B QTOF System, designed specifically for biologics and with LC-MS novices in mind. Its simple point-and-click interface makes data acquisition and processing within reach for every operator, regardless of their level of experience. High quality data with good reproducibility means you can confidently determine the accurate mass of your protein isoforms, faster and easier than before.
CESI-MS provides orthogonal separation when compared to traditional LC approaches, delivering a more thorough characterization of complex intact biologic products. SCIEX CESI-MS solutions reduce the complexity of analysis compared to standalone LC, which requires fractionation and MS detection.
Capillary electrophoresis (CE) intact protein assays provide information on purity, identity and charge heterogeneity of your intact biotherapeutics. SCIEX CE is the tried and tested platform with proven assay portability for routine intact protein analysis. Advanced temperature controlled capillary technology results in the most robust and reproducible analyses. The software interface is simple and visual and intuitive, not requiring expertise to run in routine fashion.
For labs needing to gain accurate mass information on biotherapeutics, CESI-MS offers a highly sensitive workflow that streamlines orthogonal charge variant analyses. This is particularly important for samples with limited volumes, or if you are working with toxic molecules such as antibody drug conjugates.
