Protein Electrophoresis

Protein electrophoresis is a key part of your discovery process, and Lonza has the precast gels, stains and buffers you need.  Whether you are just getting started or looking to expand your existing set up, Lonza's protein electrophoresis products have you covered.

Recently, Lonza introduced our novel PAGEr™ EX  ProSieve™ EX products for fast protein electrophoresis and staining or rapid tank transfer for western blotting. Combined they take standard protein methods from over 5 hours down to less than 1 hour:

  • 20-25 minute separation with PAGEr™ EX Polyacrylamide Precast Gels and ProSieve™ EX Running Buffer.
  • 10 minute transfer/Western blot using ProSieve™ EX Western Blot Transfer Buffer
  • 10 minute staining using ProSieve™ EX Safe Stain

  • All PAGEr™ EX gels have a 1 year shelf life

Lonza also offers traditional protein electrophoresis products like Laemmli Tris-Glycine gels for polyacrylamide gel electrophoresis (PAGE) along with high quality prepared Tris-Glycine buffer for separation of native proteins and Tris-Glycine-SDS buffer for denatured proteins (SDS PAGE).  

All precast protein gels are available in sizes that fit most chambers. We have a variety of concentrations and well formats to meet the needs for various protein electrophoresis applications. Every lot of PAGEr™ Precast gels is functionally tested and 100% guaranteed.  

Lonza is an expert in protein electrophoresis as well as DNA and RNA electrophoresis, bringing a strong history of innovation and reliability to your most important research. Our well known product brands set the standard in quality, purity and performance for electrophoresis. From detailed specifications on agarose and size markers, to specific instructions for proteins methods, we cover the basics needed to ensure successful separation, detection and analysis of proteins in agarose and polyacrylamide gels.
