Test systems with synthetic peptide substrates in haemostaseology

Area of Science:

• Biochemistry
• Clinical Chemistry
• Hematology

Background:

• Synthetic peptide substrates, developed since the 1970s, are crucial tools in hemostasis analysis.
• These substrates are short peptides (3-5 amino acids) with a chromogenic group, allowing photometric detection after protease cleavage.

Purpose of the Study:

• To review the development and application of synthetic peptide substrates in coagulation and fibrinolysis testing.
• To highlight the impact of these substrates on hemostaseology research and clinical diagnostics.

Main Methods:

• Utilizing the specific cleavage properties of various chromogenic substrates by proteases.
• Developing test systems for clotting factors, fibrinolytic factors, inhibitors, and global coagulation tests.
• Performing tests manually or on automated analytical systems.

Main Results:

• Chromogenic substrate assays offer high specificity, sensitivity, and accuracy in coagulation analysis.
• These methods have significantly advanced hemostaseological basic research, clinical investigation, and routine diagnostics.
• Current diagnostics for coagulation inhibitors and fibrinolytic parameters predominantly use chromogenic substrates.

Conclusions:

• Synthetic chromogenic peptide substrates have become indispensable in modern hemostaseology.
• Their application has led to significant improvements in the accuracy and efficiency of diagnostic testing.
• Future developments include integrating chromogenic substrates into "dry chemistry" methods.
