Used in molecular biology and biochemistry research to stabilize DNA and RNA structures. Helps in the study of nucleic acid folding, particularly in maintaining the integrity of double helix structures under varying conditions. Commonly included in buffer solutions for techniques like gel electrophoresis and PCR to enhance nucleic acid resolution and amplification efficiency. Also applied in cell culture and transfection protocols where it supports nucleic acid delivery into cells. Plays a role in preserving chromatin architecture during isolation procedures.
