Enzyme Substrates

Vector Laboratories offers many enzyme substrate kits for use with peroxidase, alkaline phosphatase, and glucose oxidase detection systems that can be used in a variety of applications including immunohistochemistry/immunocytochemistry, blot detection, and enzyme immunoassays.  Along with the traditional chromogenic substrates, Vector Laboratories also offers chemiluminescent and many proprietary colorimetric enzyme substrates. These proprietary substrates provide novel color choices essential for staining antigens in pigmented tissues and melanomas as well as for localizing multiple antigens in the same tissue section. Several substrates can be viewed under darkfield or electron microscopy. Many of our substrates have unique spectral profiles that may be useful in the co-localization of antigens using spectral imaging systems.

All Vector Laboratories substrate kit reagents are supplied in convenient dropper bottles promoting safe handling of chromogens and eliminating wait times for mixing and dissolving powders or tablets. Choose a substrate that matches the enzyme in your detection system.
