Product Description: TAPS is widely used as a buffering agent in biochemical and molecular biology research due to its effective pH range of 7.7 to 9.1. It is particularly useful in electrophoresis, protein purification, and cell culture applications, where maintaining a stable pH is critical. TAPS is also employed in enzymatic assays and diagnostic kits, as it provides a stable environment for enzyme activity and reaction consistency. Additionally, it is used in cosmetic formulations to stabilize pH and enhance product performance. Its low toxicity and compatibility with biological systems make it a preferred choice in various scientific and industrial applications.
