Immunohistochemistry Analysis: Paraffin-embedded Parkinson's diseased vascular brain (Fig.1) and human normal placenta (Fig. 2) tissue was prepared using heat-induced epitope retrieval in citrate buffer, pH 6.0. Immunostaining was performed using a 1:300 dilution of L4502-21R. Reactivity was detected using an IHC Detection Kit. Staining pattern appears in vascular tissue (Fig. 1 and Fig. 2) and lewy bodies (Fig. 1).
