Fig 4. Multimeric analysis of von Willebrand factor (VWF) in low-resolution SDS-agarose gels in patients with type 2A VWD and some discrepancy.
VWF from platelet lysate (NPt), plasmas of a normal subject (NP), patients with type 2A VWD and a patient with VWD type 2A (IIA) used as a control 2A are shown. (a-b): Patients with discrepancy between ratios and multimeric analysis; (c-d): Patients re-classified as type 2A on the basis of the genetic study.
