Technical Resources
 for Protein Preparation
 
 Protein extraction and purification represent the first of many challenges in obtaining a quality lysate or purified protein sample that delivers publication-quality Western blot results. Merck’s quality 
extraction kits and 
reagents unite superior performance with speed to reduce exposure of proteins to unfavorable conditions, leading to more stable, intact proteins for downstream analysis.
Purify Proteins
Purify your protein with 
PureProteome™ magnetic beads or agarose beads. PureProteome™ magnetic beads ensure fast, effective isolation of proteins without sample loss and are available in nickel, 
protein A, or 
protein G formats.
Concentrate and Desalt
Simultaneously concentrate and desalt your samples with 
Amicon® Ultra centrifugal filters. Their unparalleled rapid and reproducible performance minimizes protein exposure to harsh buffers. For fast and easy dialysis, use 
D-Tube™ Dialyzers, which provide 89% recovery and 99.9% desalting in as little as two to five hours.
