Protein purification is a vital step in drug discovery, therapeutics, biotech and life science research. The purification process typically involves subcellular or membrane protein extraction with cell lysis kits, separation of proteins from cell debris by filtration or spin columns, and the isolation of proteins of interest from other proteins and impurities with affinity purification (including fusion protein tags and antibody binding proteins A, G and L), immunoprecipitation or chromatographic methods, such as ion exchange, size exclusion and immobilized metal affinity chromatography. All purification methods come in multiple formats for your laboratory needs, including agarose or magnetic beads, resins, columns and filter plates.

ProteaseMax™ Surfactant is a high-quality reagent for use in protein and peptide sample preparation. ProteaseMax™ Surfactant solubilizes proteins and ensures fast and improved protein digestion with trypsin or chymotrypsin. It is designed to degrade over the course of a digestion reaction, yielding products that are compatible with downstream methods such as mass spectrometry (MS) and liquid chromatography (LC). For…
The Strep-tag® / Strep-Tactin® purification system allows the isolation of above 95% pure and functional proteins after one chromatographical step. The Strep-tag system is based on the highly selective and easily controllable interaction between the Strep-tag II peptide and the specially engineered streptavidin called Strep-Tactin. The binding affinity of Strep-tag II to Strep-Tactin is nearly 100 times higher than to Stre…
The recently launched Strep-Tactin® Superflow® high capacity resin offers improved binding capacity but identical high protein purity compared to standard Strep-Tactin® Superflow®.
