Used extensively in molecular biology for buffering cell cultures and biochemical reactions, it maintains a stable pH environment crucial for DNA and RNA manipulation. Ideal for PCR, electrophoresis, and protein purification, it ensures optimal conditions for enzyme activity and nucleic acid stability. Commonly employed in cell-based assays and tissue culture, it supports cell growth and viability. Its high purity makes it suitable for sensitive applications like cloning and sequencing, where contamination could compromise results.
