CE-SDS purity analysis kits
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
