Labelled reagent products are specialized chemicals tagged with detectable markers like fluorescent dyes, radioisotopes, or enzymes. They are essential in various biochemical and molecular biology applications for tracking, detecting, and quantifying specific molecules or interactions. These reagents enhance techniques such as immunoassays, microscopy, and flow cytometry, providing precise and reliable results. High-quality labelled reagents are crucial for accurate diagnostics, research, and development in scientific laboratories.
