Protein analysis equipment and supplies
Protein analysis is a key process to study, develop, and produce antibodies and other proteins. To characterize and quantitate proteins with accuracy, Cytiva provides a wide range of solutions for label-free surface plasmon resonance (SPR), electrophoresis, blotting, immunoassays, as well as labeling, hybridization, and molecular imaging. These products help to separate, detect, and analyze proteins precisely, supporting workflows from sample preparation to impurities testing. Browse our range of robust instruments and high-quality reagents to speed up and simplify research and manufacturing.

Agarose IEF
Agarose IEF
Agarose NA
Agarose NA has been prepared to give the optimal combination of these properties: Reliable separation of nucleic acids; low inhibition of enzyme activity on recovered material; and high gel strength.
Amdex - Enzyme Conjugates for ELISA, Antibody Reagents
Amdex - Enzyme Conjugates for ELISA high performance conjugates are based on a unique chemistry - a hydrophilic straight chain dextran backbone to which many hundreds of enzyme molecules (for example, horseradish peroxidase or alkaline phosphatase) are covalently coupled.
Amdex - Enzyme Conjugates for ELISA, Streptavidin
Amdex - Enzyme Conjugates for ELISA high performance conjugates are based on a unique chemistry - a hydrophilic straight chain dextran backbone to which many hundreds of enzyme molecules (for example, horseradish peroxidase or alkaline phosphatase) are covalently coupled.
Amersham Cy3 and Cy5™ Maleimide Mono-Reactive Dye Packs
Cy3 and Cy5 maleimide mono functional dyes are especially suitable for highly selective peptide, oligonucleotide and protein labeling via thiol maleimide coupling.
Amersham CyDye NIR secondary antibodies
Fluorescence detection is a direct Western blotting method in which a secondary antibody is conjugated to a fluorophore, avoiding the need for ancillary detection reagents. Different fluorophores are available for signal detection at either visible light or near-infrared (NIR) wavelengths. Amersham CyDye 700 and 800 secondary antibodies are labeled with NIR fluorophores that emit light at wavelengths of 700 nm or 800 nm. By using Amersham CyDye 700 and 800 secondary antibodies together with a pair of appropriate rabbit or mouse primary antibodies, you can perform multiplexed experiments. Key benefits:
