Product Catalog 
Browse our online catalog by application to find the product you need.

Protein Expression Systems 
Vectors, plasmid controls and cell extracts for high-fidelity cell-free in vitro translation, recombinant protein expression and post-translational modification from RNA or DNA templates. 


Cell Lysis and Protein Extraction 
Protease inhibitors, phosphatase inhibitors, detergents and specialized reagents designed for efficient organelle isolation, subcellular fractionation and protein solubilization from a variety of cell and tissue types. 


Protein Affinity Purification 
Agarose beads and other resins for specific purification of proteins and other target molecules, kits for immunoprecipitation (IP), activated resins for covalent immobilization of ligands, and columns for packing affinity resins. 


Dialysis, Desalting and Buffer Exchange 
Concentrators, dialysis cassettes, desalting columns and other buffer-exchange devices for removing contaminants and concentrating samples to ready them for long-term storage or to make them compatible with downstream applications. 


Protein Assays and Quantitation 
Assay reagents, kits and standards to determine total protein concentration of samples containing different buffer components; protein quantitation is often necessary for isolation, separation, and analysis of proteins by biochemical methods. 


Protein Electrophoresis and Staining 
Precast gels, running buffers, molecular weight markers, and gel stains necessary for sample preparation, loading and analysis when studying proteins by electrophoresis (SDS-PAGE). 


Western Blotting, ELISA and Cell Imaging 
Blocking buffers, secondary antibody conjugates, and substrate detection reagents (colorimetric, chemiluminescent and fluorescent) for sensitive and consistent protein analysis by Western blotting, ELISA and immunohistochemistry (IHC). 


Protein Interactions 
Affinity, crosslinking and detection reagents and kits designed to identify and characterize protein interactions (both stable and transient) by immunoprecipitation, pull-down, far-Western blotting, crosslinking and label transfer. 


Protein Mass Spectrometry and HPLC 
Reagents and kits for peptide and protein analysis (proteomics) by mass spectrometry (MS) and high-pressure liquid chromatography (HPLC). Includes sample prep tools, mass-tagging (TMT) and isotope labeling (SILAC) kits, and derivatization reagents. 


Protein and Antibody Labeling 
Labeling reagents and kits to label an antibody or other protein to make a fluorescent probe, enzyme conjugate, biotinylated binding reagent or iodine labeled tracer for detecting proteins in tissues, cells, or biochemical assays. 


Crosslinking and Protein Modification 
Reagents to modify proteins by crosslinking, fragmenting, denaturing, reducing disulfides, or attaching various prosthetic groups (e.g. PEGylation) to allow manipulation and study of protein function and interactions in any environment. 


Antibody Production and Purification 
Carrier proteins, immunogen preparation reagents, isotyping kits, antibody purification resins and immunoglobulin fragmentation kits to easily create and purify antibodies for any immunodetection technique. 


Antibodies 
Specific polyclonal and monoclonal antibodies to probe, stain, locate, purify and detect virtually any protein, plus secondary antibodies conjugated to the widest array of fluorescent and enzymatic labels for high sensitivity detection. 


Target Specific Assay Kits 
ELISA, ELISPOT, fluorescent arrays and high-content screening (HCS) kits for detection and measurement of specific cytokines, chemokines, cell signaling proteins, transcription factors, and other cellular targets.  


Books 
A collection of books with topics of value to life scientists who work with proteins.
