Laconic8 (link), ATeam, or FLIIPglu700 containing plasmid (Addgene: 44238, 51958, and 17866 respectively) were cloned into Ad5 adenovirus by VectorLabs for construction of Adenovirus-Laconic (Ad-Lac), Adenovirus-ATeam (ad-ATeam), or adenovirus-FLIIPglu700 (ad-Glu). Ad-LifeAct-RFP (ad-LifeAct) was from Ibidi (60122). For transduction into endothelial cells, Ad-Lac at 50:1 multiplicity of infection (MOI), ad-ATeam at 100:1 MOI, and ad-Glu at 200:1 MOI in 1:1 EGM2 media:Opti-MEM (ThermoFisher, 11058021) and 3 μL GeneJammer (Agilent, 204130) per milliliter of final volume was added for 1 hour before replacement of media. For migration and contraction experiments, ad-Lac and ad-LifeAct were co-transduced each with MOI 50:1. Endothelial cells were used 48 hours post transduction to allow for cell recovery and maximal fluorescence.
