Reagents to add a biotin group to proteins, peptides or antibodies. Choose a biotinylation reagent based on the chemical group you would like to modify: Biotinylation Reagent Selection Guide.

Reagents for every step of the antibody production process from animal immunization to antibody purification, & characterization. This includes: primary and secondary antibodies, adjuvants and carrier proteins, antibody purification resins and buffers, antibody isotyping, antibody fragmentation and, antibody labeling.

Used for protein conjugation to solid surfaces (microplates, beads, particles, microspheres, membranes, glass slides), enzymes, antibodies, chromatography supports and other proteins of interest. See our Crosslinker Selection Guide. 

Use our DyLight dyes to add fluorophores with extended photostability, high quantum yield and sharp emission spectra. Label any biomolecule for easy detection.

Exchange buffers easily and quickly. Resins available to remove endotoxins, detergents or salts from a protein sample. Slide-A-Lyzer cartridges for quick and efficient dialysis.

Tools available for Rapid Equilibrium Dialysis (RED) to assess drug plasma protein binding as well.

Tools to quantitate proteins levels by mass spectrometry analysis.

High purity detergents for various applications.

Reagents to extract and stabilize proteins optimized to extract protein from cells and tissues.
