Figure 2. Immunoprecipitation analysis of anti-Seca.
Paternal and maternal platelets were surface labelled with biotin and lysed. Labelled platelet lysates were precipitated with control serum (lanes 1), anti-HPA-1a antibodies (lanes 2) and maternal serum (lanes 3). Immunoprecipitates were run on 7.5% SDS-PAGE under non-reducing conditions, transferred onto nitrocellululose membrane and visualised by streptavidin-chemiluminescence system.
