Immunohistochemistry (IHC) is a cornerstone technique in biological research and diagnostics, allowing scientists to visualize the location and distribution of specific antigens within tissue samples. Central to the success of IHC is the choice of detection system, and for many, this involves chromogenic substrates. Among these, 3-Amino-9-ethylcarbazole (AEC), also known by its CAS number 132-32-1, stands out as a highly effective and widely utilized reagent.

AEC is a synthetic organic compound that, when acted upon by an enzyme like horseradish peroxidase (HRP) in the presence of hydrogen peroxide, produces an insoluble, colored precipitate. This precipitate is typically reddish-brown, providing a distinct visual signal that marks the presence of the target antigen. Unlike some other chromogens, the precipitate formed by AEC is generally more stable in alcohol-based counterstains, a significant advantage when specific counterstaining protocols are employed.

For researchers and laboratory managers seeking to purchase or source AEC, understanding its benefits and where to find high-quality material is paramount. As a leading chemical supplier, we understand the critical need for consistent purity and reliable availability. Our commitment as a manufacturer ensures that we can meet the demands for AEC, whether for small-scale research or larger production needs.
