5’-Phosphodiesterase is an enzyme used in molecular biology research, particularly for the study and analysis of nucleic acid structures. This enzyme hydrolyzes phosphodiester bonds at the 5’ end of DNA or RNA strands, enabling specific cleavage or fragmentation of nucleic acids. It is ideal for preparing samples for sequencing, gene analysis, or DNA library construction. Additionally, it is employed in PCR techniques and genetic diagnostics to control or inhibit unwanted reactions by removing residual primers after amplification.
