Protein Purification Products & Reviews
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.

Catch and Release® v2.0 Reversible Immunoprecipitation System
MerckThis kit allows for quick and reproducible immunoprecipitation (IP) by using a spin column. The system is more reproducible than regular IP's, which are problematic with regards to washing the protein A/G agarose without disrupting the agarose bed. The binding of the antibody/antigen complex in Catch and Release® is reversible, and elution of the immune complex can occur with native or denaturing buffers. The system has been…
Montage® Antibody Purification Kits
MerckMontage Antibody Purification Kits are designed for fast and easy antibody purification from serum, ascites or cell culture supernatants. The kits include spin columns pre-packed with high capacity PROSEP-A or G media. There are no pumps to setup. No columns to pack. All you need is a centrifuge to purify 10–20 mg in less than 60 minutes.The protocol is easy to follow and, unlike traditional gravity flow methods, the use of ce…
