Protein quantification systems are critical analytical tools used to measure protein concentration, assess purity, and enable downstream proteomic, biochemical, and diagnostic workflows. These systems are essential in drug development, biomarker discovery, protein expression analysis, vaccine production, and clinical diagnostics, where precise quantification of protein content is key to experimental success and regulatory compliance.
Protein quantification can be performed using a range of detection methods including UV absorbance at 280 nm, colorimetric assays such as Bradford, BCA, and Lowry, and fluorescence-based detection for enhanced sensitivity. Automated systems streamline these workflows by allowing for multi-sample throughput, reproducible results, and data integration with LIMS or other software platforms.
Applications include measuring protein yields from recombinant expression systems, evaluating purity during column chromatography, determining protein-to-nucleic acid ratios, and validating samples for Western blotting, ELISA, or mass spectrometry. In biopharma labs, protein quantification supports formulation development, stability studies, and quality control (QC) of biologic products.
Modern protein quantification systems often feature microplate readers, spectrophotometers, or microfluidic analyzers, with capabilities for real-time quantification, pathlength correction, and automated calibration curves. Many systems support small-volume measurements, which is especially important when working with precious or low-concentration samples.
