Summary
Von Willebrand Factor (vWF) exists as high molecular multimers in plasma. Multimer sizing using methods like two-dimensional crossed immunoelectrophoresis is crucial for diagnosing and classifying von Willebrand
Area of Science:
- Biochemistry
- Hematology
- Immunology
Background:
- Normal plasma contains Von Willebrand Factor (vWF) as high molecular multimers.
- These multimers range in size from 8x10^5 to over 15x10^6 Daltons.
Purpose of the Study:
- To highlight the historical significance of multimer sizing in understanding vWF structure.
- To underscore the role of vWF multimer analysis in diagnosing von Willebrand's disease (vWD).
Main Methods:
- Two-dimensional crossed immunoelectrophoresis (2D-IEP) was an early method for vWF multimer investigation.
- Variations of multimer sizing techniques are employed.
Main Results:
- The multimeric structure of vWF has been characterized.
- Multimer sizing has been established as a diagnostic tool.
Conclusions:
- The analysis of vWF multimer size is fundamental in the diagnosis and classification of vWD.
- Historical methods like 2D-IEP laid the groundwork for current diagnostic approaches.
