title: Multimeric analysis of von Willebrand factor by vertical sodium dodecyl sulphate agarose gel electrophoresis, vacuum blotting technology and sensitive visualization by alkaline phosphatase anti-alkaline phosphatase complex.
abstract: To detect von Willebrand factor multimers in plasma samples and factor VIII concentrates, a vertical discontinuous SDS electrophoresis was developed. A vacuum blotting system allowed to improve the transfer to the nitrocellulose membrane. The visualization of the separated multimers was sensitized by applying an alkaline phosphatase anti-alkaline phosphatase staining technique. The reported method clearly shows structural abnormalities of von Willebrand factor and deficiency of high multimers, the vacuum transfer is efficient and the sensitivity of the staining system is very high.
