Deoxyribonucleic acid, single stranded from salmon testes CAS Number

Single-stranded salmon testes DNA functions as a non-specific nucleic acid blocking agent that reduces background interference in hybridization assays. By competing for non-specific binding sites on solid membranes, it prevents unwanted probe adsorption to non-target nucleic acids and surfaces. This blocking action significantly improves the specificity and signal-to-noise ratio in nucleic acid hybridization techniques, facilitating clear detection of target sequences.
