Magen has published DNA and RNA Extraction Troubleshooting, a technical resource for laboratories and distributors supporting nucleic acid sample preparation. The guide brings common extraction problems together in a structured reference, linking typical observations with possible causes and practical checks.

From observations to practical checks

Topics include low recovery, incomplete lysis, column blockage, magnetic bead handling, abnormal purity ratios, unwanted DNA or RNA, degradation and poor downstream performance. The guide covers column, magnetic bead and precipitation workflows, with attention to sample characteristics, target nucleic acids and the point at which a problem first appears.

Throughout the article, measurements are interpreted alongside controls and assay requirements. Examples explain why concentration differs from total yield, why absorbance ratios alone cannot establish inhibition, and how suitable comparisons can help distinguish extraction problems from downstream assay failure.

A resource for laboratories and distributors

The guide is designed to support routine troubleshooting and technical discussions with customers. It complements Magen's purchase guides and product-specific protocols by explaining the factors behind common workflow problems and the information needed to investigate them. Protocol-specific limits and operating conditions remain essential when applying these checks.
