Impurity detection from development to QC

CE-SDS purity analysis kits

Obtain fast, quantitative data for purity and integrity analysis of therapeutic proteins.

Rapid determination of protein purity with capillary electrophoresis sodium dodecyl sulfate

CE-SDS is widely used throughout therapeutic drug development for lot release, stability testing, formulation-buffer screening, process development, cell line development and product characterization.  

Maximize the way you work with validated kits and methods designed to optimize resolution and throughput. 

Validated kits for CE-SDS workflows

SDS-MW analysis kit

The SDS-MW analysis kit is designed for use on the PA 800 Plus system and used for the separation and sizing of protein-SDS complexes. 

  • Estimate molecular weight of an unknown protein 

  • Quantify the amount of protein 

  • Determine the purity of a protein product. 

This kit uses a replaceable gel matrix formulated to provide an effective protein sieving range of approximately 10kDa to 225kDa.

Includes reagent volumes for analysis of 100 samples and components allowing for protein sizing. 

BioPhase CE-SDS protein analysis kit

As the drug development pipeline evolves, so do throughput needs. This kit is for use on the BioPhase 8800 system, designed to meet throughput demands by enabling 8 samples to be run in parallel, significantly increasing throughput and eliminating analytical bottlenecks.

Flexible workflows tailored for high-throughput CE-SDS analysis, for the BioPhase 8800 system optimize time to answer while ensuring excellent intermediate precision, accuracy, and separation efficiency.

IgG purity and heterogeneity kit

This kit is designed for use on the PA 800 Plus and is used to assess the purity and heterogeneity of IgG molecules in both a reduced and non-reduced state, and will detect impurities as low as 0.1%.

This kit provides reagent volumes for analysis of 100 samples.
