Biotinyl tyramide serves as a substrate for the horseradish peroxidase enzyme, acting as a reagent to amplify signals in immunohistochemistry. The Fluorescence-based tyramide signal amplification (TSA) method, widely used in various applications, enhances detection sensitivity up to 100-fold compared to traditional procedures. Chemodex provides a diverse range of Active Pharmaceutical Ingredients (APIs), isolated natural compounds, and Difficult to Access Building Blocks for laboratory experiments in organic chemistry, supporting the synthesis of fluorescent probes and the development of APIs.
