SEC-MALLS Services for Peptide Development

Related topics:

Size exclusion chromatography (SEC) is the most common technique for aggregate determination. Key advantages are easy handling and good reproducibility. We offer services that include method development of SEC/SEC-MALLS methods and the inclusion of multiangle laser light scattering detection (MALLS) to already existing SEC methods.

Peptides are molecules that are at the lower edge of the size range suitable for classical protein analysis techniques, and too large for established methods for small molecule analysis. Their size thus poses a challenge in analytical method development. Considering this, SV-AUC is an excellent choice for purity assessment of peptide products. Advanced data evaluation approaches are necessary to achieve a resolution that is adequate for this application. We have set up our own computer cluster at ZentriForce Pharma to offer such services, without the need for costumer data to leave our facility. Please follow the link for more information.

Dynamic light scattering is a crucial part of peptide development. It is a fast and efficient screening method for aggregate and particle detection.  In addition, our instrument, the DynaPro®Plate Reader III, allows us to apply static light scattering (SLS) to characterize your peptides. For more information about the use of DLS in peptide development please follow the link.

Although we routinely conduct biosimilarity and gene therapy studies, we are experienced in the development of asymmetrical flow field-flow fractionation (AF4) methods for peptide samples as well.  These experiences also include the application of AF4 within the development of a new peptide-based APIs or within a biosimilarity study (e.g. glatiramer acetate). For more information about the use of AF4 in peptide development please follow the link.

Size Exclusion Chromatography (SEC – MALLS) for Peptide Development

Size exclusion chromatography (SEC) is the standard technique for aggregate determination in biopharmaceutical development. Obvious advantages are the easy handling and the good reproducibility that this method provides. We offer services that range from method development of SEC / SEC-MALLS methods to the inclusion of multiangle laser light scattering detection (MALLS) to already existing SEC methods.

Size exclusion chromatography method development for peptide samples is a challenging task. The species’ small size results in a low resolution. Nonetheless, relying on our experience, state-of-the-art instrumentation and dedicated team, we can offer cutting edge analytical method development.

Why you should use a SEC-MALLS Instrument for Method Development 

The separation of species in SEC is based on an interaction with a stationary phase that may result in unwanted effects on sample components and elution profiles.  Species are indeed not always separated solely by size. In some cases, a combination of different separation mechanisms may be observed. To avoid misleading results, it is essential to develop a method that is not solely based on the observed elution pattern of the sample, but that also characterizes each observed eluted species individually. This is possible by coupling a multiangle laser light scattering detector (MALLS) with the HPLC instrument. The state-of-the-art MALLS detector ( Wyatt DAWN Heleos II ) at ZentriForce Pharma allows us to obtain the molecular weight of all observed species. With this information we can develop a truly feasible SEC method for you. Please follow the link to our light scattering theory page to learn more about light scattering theory, including MALLS.

SEC-MALLS Instrumentation

Our scientists have worked with a wide range of biopharmaceutical products. Our experience keeps your expenses low. Combining the Agilent 1260 Infinity II HPLC, Wyatt DAWN Heleos II MALLS detector and a Wyatt Optilab T-rEX RI detector, we  work with cutting edge instrumentation that offer highest sensitivity,  precision and reproducibility.
