Why 5’ → 3’ Exonucleases Product Type Segment Dominated the Exonucleases Market?
The 5’ → 3’ exonucleases segment held a dominant position in the market with a share of 40% in 2025. 5’ → 3’ exonucleases are widely used to digest nucleotides in the 5’ to 3’ direction on a template ahead of polymerase activity. One of the common examples of 5’ → 3’ exonucleases is Taq polymerase, which catalyzes the cleavage of 5’ DNA flaps from a DNA duplex. The major advantages of these exonucleases are that they can remove mononucleotides or up to 10 nucleotides simultaneously.
3’ → 5’ Exonucleases
The 3’ → 5’ exonucleases segment is expected to grow at the fastest CAGR in the market during the forecast period. 3’ → 5’ exonuclease activity is known as proofreading activity that digests nucleotides with 3’ hydroxyl groups from the 3’ to 5’ direction. They correct mismatched base pairs and terminal 3’ digestion, as well as prevent mutations. They can remove one mononucleotide at a time, allowing researchers to focus on a single nucleotide precisely.
How the DNA Sequencing & NGS Workflows Segment Dominated the Exonucleases Market?
The DNA sequencing & NGS workflows segment held the largest revenue share of 35% in the market in 2025, due to the need for researchers to study disease progression and develop innovative diagnostics and therapeutics. Exonucleases facilitate the precise removal of nucleotides from DNA/RNA. DNA sequencing is an essential procedure to determine the order of DNA bases to read genetic instructions. The growing demand for point-of-care diagnostics boosts the segment’s growth.
PCR Clean-up & Sample Preparation
The PCR clean-up & sample preparation segment is expected to grow with the highest CAGR in the market during the studied years. PCR clean-up is used to purify DNA and remove remaining primers and dNTP left from a PCR reaction. Exonuclease-based real-time PCR uses Taq polymerase to measure PCR product accumulation. PCR clean-up is an essential step as it may interfere with the PCR results.
Why Did the Enzyme-based Digestion Systems Segment Dominate the Exonucleases Market?
The enzyme-based digestion systems segment contributed the biggest revenue share of 50% in the market in 2025, due to the need for precise sample preparation for various applications.
