Furthermore, the analysis is incredibly swift, taking just a few seconds, and requires only a minimal sample volume of 1-2 microliters. Crucially, the ratio of absorbance at 260nm to 280nm (A260/A280) provides a quick snapshot of purity, indicating the presence of protein or phenol contamination.
Nanodrop Rapid Quantification Method: Speed and Sample Efficiency
The resulting A260/A280 and A260/A320 ratios are then compared against established purity ranges to give an immediate quality assessment. Additionally, it serves a vital function in monitoring protein purification and verifying the concentration of enzymes and other reagents.
This is where the Nanodrop instrument has become an indispensable tool for researchers, clinicians, and quality control laboratories. Its primary role is in nucleic acid quantification for downstream applications like PCR, cloning, sequencing, and microarray analysis, where precise input is essential.
Nanodrop Rapid Quantification Method for Nucleic Acid and Purity Assessment
Integration into Quality Control Workflows In industrial and clinical laboratories, the Nanodrop plays a critical role in quality assurance. For samples with significant cloudiness or particulates, the spectrophotometric measurement may be less accurate, making the fluorometric method a better alternative.
