Article Snippet: DIV14-16 Primary hippocampal mouse neurons, plated in 35 mm Mattek No1.5 dishes were simultaneously transfected via combiMag and Lipofectamine with 0.5 μg EB3-miRFP703 (Addgene #79994) or mRuby-Synaptophysin [(pEF Synaptophysin-mRuby was a gift from Edwin Chapman (Addgene plasmid # 188980; http://n2t.net/addgene:188980 ; RRID:Addgene_188980)] or mApple-PSD95 [mApple-PSD95-N-14 was a gift from Michael Davidson (Addgene plasmid # 54941; http://n2t.net/addgene:54941 ; RRID:Addgene_54941)] and either 0.5 μg NC-GFP (Origene TR30013) or KIF11-shRNA-A (Origene TG501174) or tagged KIF11 constructs.
