Used in biomedical research to quantify urine protein levels in human samples, aiding in the assessment of kidney function and detection of renal diseases such as nephrotic syndrome and glomerulonephritis. Enables high-throughput analysis in clinical laboratories and research settings for monitoring disease progression and evaluating treatment efficacy. Supports studies in diabetes, hypertension, and autoimmune disorders where proteinuria is a key biomarker. Provides a sensitive and specific method for measuring low concentrations of protein in urine, essential for early diagnosis and intervention.
