Aurintricarboxylic acid is widely used in biochemical research as a potent inhibitor of nucleases, particularly RNases and DNases. This property makes it valuable in protecting RNA and DNA during extraction and purification processes, ensuring the integrity of nucleic acids for downstream applications like PCR, sequencing, and cloning. Additionally, it is employed in studies involving apoptosis, as it inhibits endonucleases responsible for DNA fragmentation during programmed cell death. Its ability to chelate metal ions also finds utility in research exploring metal-dependent enzymatic activities. Beyond molecular biology, aurintricarboxylic acid has been investigated for its potential antiviral properties, particularly in inhibiting the replication of certain viruses by interfering with viral polymerase activity.
