Protein Assays
Accurately quantifying total protein concentration is a key step in most experiments and workflows involving the isolation, separation, and analysis of proteins. We offer a variety of assay reagents, kits, and standards for protein quantitation using fluorescent or colorimetric detection with fluorometers, spectrophotometers, and plate readers. Additionally, our products are offered with dilution-free protein standards for added ease of use and reduced setup time when generating your standard curve. Dilution-free protein standards are a set of prediluted standards packaged in a multichannel pipette-compatible format, allowing you to easily transfer a full dilution series to your microplate at once. No single reagent can be considered the ideal or best protein assay method. Each method has its advantages and disadvantages. Identify, compare, and choose the best protein assay using the protein assay interactive product selector. Click “Learn more” to browse our broad portfolio and interactive selection tool: filter and compare selections based on sample type, assay time, readout (colorimetric or fluorescent), and compatibility with detergents or reducing agents.
Precast protein gels
Explore our protein gel options. Choose from precast polyacrylamide gel electrophoresis (PAGE) chemistries – Tris-Glycine or Bis-Tris, designed for specific applications including broad range, high – Tris-Acetate, or low molecular weight – Tricine separations, SDS-PAGE, native PAGE, or IEF.

iBlot 3 western blot transfer system
The next-generation dry protein transfer device with ready-to-use consumables that can deliver high performance and convenience. Perform reliable, high-quality transfers fast—in as few as three minutes. In addition, two independently controlled transfer stations allow you to share the device with your coworker, simultaneously running a total of four mini gels or two midi gels with two different programs. With the iBlot 3 system, you can achieve as good or better protein transfer efficiency compared to wet tank transfer and other rapid transfer methods. The preassembled single-use consumables and ultrafast transfer methods help eliminate variability—enabling consistent and repeatable results. In addition, the robust design has built-in cooling to reduce heat buildup and facilitate run-to-run consistency.
iBind western systems
Two devices, one simple technology for automated western blot processing
Invitrogen iBind Western Systems—no shakers, no trays, no timers. Set up in minutes and walk away. The Invitrogen iBind Western Systems are western blot processing benchtop devices that utilize sequential lateral flow (SLF) to perform hands-free blocking, antibody binding, and washes. In less than 3 hours, blots are processed and ready for final detection. You can continue to use your existing chromogenic, chemiluminescent, or fluorescent western blotting protocols, along with your choice of primary antibody or secondary antibody conjugates of HRP, AP, or fluorescent dyes.
Antibodies for Western Blotting
The right antibodies are essential for clean, definitive, and reproducible western blot results. We offer more than 48,000 highly specific and sensitive primary and secondary antibodies to help you gather quality western blot data. All of our antibodies are validated to perform in the stated application and species. HRP- and AP-conjugated secondary antibodies are also available in various degrees of purity to meet all your western analysis needs.

Western Blot Detection Reagents
With a variety of detection techniques for western blotting-chemiluminescence, fluorescence, or colorimetric, to choose from, you can select a technology to match your experimental requirements by clicking “Learn more” below.
Chemiluminescent substrates are popular because they offer several advantages over other detection methods. These advantages have allowed chemiluminescence to become the detection method of choice in most protein laboratories. Key highlights: Greatest sensitivity; Detection and quantitation for a large range of protein concentrations.
Fluorescent reagents are growing in popularity for western blotting because they offer increased time savings over chemiluminescent detection and reduced chemical waste compared to both chemiluminescent or chromogenic detection systems. Key highlights: Multiplexing capability; Direct signal.
