Protein Research Reagents
Protein Research Reagents
The widest selection of tools for sample preparation, protein modification and protein detection to accomplish your research as accurately and efficiently as possible.
Select the simplest and best method to detect your protein, whether it's the most sensitive ECL detection system for western blotting, the most reliable BCA protein assay, or an In-Cell ELISA to detect a specific cellular protein. Choose from sample preparation including products for cell lysis and protein extraction, dialysis and desalting or protein purification. Investigate our protein modification products to discover the best method for labeling a protein with biotin or a fluorophore, choose the right crosslinker to discover a protein interaction, or find just the right PEGylation reagent.
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.
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.
Cell Lysis and Protein Extraction
Protease inhibitors, phosphatase inhibitors, detergents and whole cell lysis reagents designed for efficient organelle isolation, subcellular fractionation and protein solubilization from a variety of cell and tissue types.
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.
Protein Assays
Protein assay kits, reagents 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.
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 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.
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.
