Optimizing the purification of High Molecular Weight Genomic DNA: Overcoming Key Challenges

Posted by The Protein Man on Jul 17, 2025 2:21:22 PM

Extracting high-molecular-weight (HMW) genomic DNA while preserving its integrity presents significant challenges. The primary objective is to obtain long, intact DNA strands free from degradation and contaminants, yet maintaining such structural integrity is far from straightforward. Mechanical shearing and enzymatic activity often compromise yield and purity, hindering the isolation of DNA suitable for cutting-edge applications.  Successfully navigating these challenges requires precise methodologies, specialized reagents, and a thorough understanding of the factors that influence DNA stability.
