Western blots provide the ability to detect specific protein expression levels from cells or tissues in a convenient format for rapid evaluation that can also be quantitative and offer unparalleled sensitivity. With a variety of detection techniques (chemiluminescence, fluorescence, or colorimetric) to choose from, you can select a technology to match your experimental requirements and the instruments you have available. Whether for quick visualization or precise quantitation, single-probe or multiplexing, we offer a range of reagents and kits for western blot detection and subsequent analysis.
