Used in molecular biology research to study DNA hybridization and nucleic acid interactions. Serves as a synthetic polynucleotide template in enzymatic assays, particularly for DNA and RNA polymerases. Helps in investigating the stability and kinetics of double-stranded nucleic acid structures. Also employed in the development and calibration of diagnostic techniques that rely on sequence-specific binding, such as biosensors and microarrays. Its defined base composition makes it useful for probing the effects of homopolymeric sequences on protein-nucleic acid interactions.
