Sample preparation is critical to prepare and purify proteins for functional or structural studies. Our complete range of reagents and enzymes for cell lysis and protein extraction provide you with an array of options so that you can put together the perfect extraction protocol for your particular cells and protein. We offer a wide vareity of products for protein purification, including agarose resins, magnetic beads, and FLAG® tag technology. Our membrane-based, protein sample concentration technologies, including tangential flow filtration (TFF)-based separation, enable fast, easy concentration, desalting and buffer exchange.
Centrifugal and pressurized ultrafiltration devices for protein concentration, desalting, buffer exchange, separation, and diafiltration of biological and environmental samples in preparation for downstream applications.
Fully validated subcellular fractionation and protein enrichment and depletion kits tailored for proteomics research and downstream applications including activity assays, protein microarrays, immunoblotting, ELISA, 2D gel electrophoresis, and mass spectrometry.
Affinity purification resins and buffers for purifying His-tagged, GST-tagged, FLAG® tagged, S-tag™, Strep-Tag II, and T7-tagged proteins under native or denaturing conditions using batch or column purification techniques.
Protease and phosphatase inhibitors and cocktails to prevent proteolysis and protein dephosphorylation, and to preserve the active state of proteins during cell lysis, protein extraction, and sample preparation.
