Clinical analysis of human urinary proteins using high resolution electrophoretic methods

Area of Science:

• Biochemistry
• Analytical Chemistry
• Clinical Diagnostics

Background:

• Human urinary protein analysis is vital for diagnosing and monitoring numerous health conditions.
• Electrophoretic techniques have evolved significantly, offering enhanced resolution and sensitivity for protein profiling.
• Understanding the capabilities of different electrophoretic methods is key to accurate urinalysis.

Purpose of the Study:

• To review the application of high-resolution electrophoretic techniques for human urinary protein analysis.
• To provide a historical perspective on the use of these methods in urinalysis.
• To detail the clinical applications of electrophoretic methods in various renal and urogenital tract conditions.

Main Methods:

• Isoelectric focusing (IEF)
• Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE)
• Two-dimensional electrophoresis (2-DE)
• Capillary electrophoresis (CE)

Main Results:

• The review tabulates information on sample preparation, electrophoretic systems, detection methods, and clinical applications for each technique.
• Historical context of each method's use in urinalysis is provided.
• Detailed applications in investigating renal disease, transplantation, Bence Jones proteinuria, diabetes mellitus, cadmium toxicity, nephrolithiasis, and urogenital cancers are discussed.

Conclusions:

• Electrophoretic methods like IEF, SDS-PAGE, 2-DE, and CE are powerful tools for high-resolution analysis of human urinary proteins.
• These techniques have broad clinical applications in diagnosing and managing a wide range of renal and urogenital tract disorders.
• The comprehensive review aids researchers and clinicians in selecting appropriate methods for specific diagnostic challenges.
