​Overcoming Polysaccharides and Polyphenols: Improving Plant DNA and RNA Extraction Reliability

Polysaccharides and polyphenols are major inhibitors in plant DNA and RNA extraction.
This article discusses why inhibitor rich plant samples are challenging, why RNA is particularly sensitive, and how laboratories select appropriate workflows to improve reproducibility across diverse sample types.

Why DNA Extraction from Inhibitor‑Rich Environmental Samples Is So Challenging

Environmental DNA (eDNA) analysis is widely used in microbiome research, environmental monitoring and ecological studies. However, extracting high-quality DNA from inhibitor-rich environmental samples such as soil, sludge and water filters remains a major technical challenge.
This article explains why environmental DNA extraction is inherently difficult, how PCR failure is often a downstream symptom of inhibitor interference,and what key factors should be considered to improve reproducibility in eDNA workflows.
