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.
Thousands of the best primary and secondary antibodies, plus purified recombinant proteins, custom-synthesized peptides, heavy peptides and peptide libraries.
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.
Carrier proteins, immunogen preparation reagents, isotyping kits, antibody purification resins and immunoglobulin fragmentation kits to easily create and purify antibodies for any immunodetection technique.
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.
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 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.
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.
Precast gels, running buffers, molecular weight markers, and gel stains necessary for sample preparation, loading and analysis when studying proteins by electrophoresis (SDS-PAGE).
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.
Vectors and reagent kits for high-fidelity, cell-free, human in vitro translation (human protein expression) and luciferase assays based on spectrally distinct Cypridina, Gaussia, Renilla and firefly luciferase reporters.
