STE Buffer is widely used in molecular biology for various applications involving nucleic acids. It is commonly employed in the extraction, purification, and storage of DNA and RNA due to its ability to maintain stability and prevent degradation. The buffer is also utilized in gel electrophoresis to prepare samples and ensure consistent migration of nucleic acids. Additionally, STE Buffer is often used in cell lysis procedures to isolate genetic material while preserving its integrity. Its balanced composition makes it suitable for hybridization experiments and other techniques requiring a stable pH and ionic environment.
