Biochemical reagents include a wide range of chemicals and compounds used in molecular biology, enzymology, and cell culture experiments. These reagents are critical for DNA/RNA extraction, protein quantification, enzyme assays, and metabolic pathway studies. They must be of high purity and often require cold storage or sterile handling.

Common examples include buffers, enzymes, substrates, indicators, and electrophoresis reagents. Biochemical reagents are packaged in vials, microtubes, or sealed ampoules and require precise measurement tools to ensure experimental integrity. These reagents are indispensable in medical research, diagnostics, and life science innovation.
