Levels of C3 measured by ELISA in the apical and basal conditioned media of RPE cultures showed increased levels of C3 in Efemp1R345W/R345W:C5+/+ and Efemp1R345W/R345W:C5-/- cultures compared to controls. Data from apical and basal side were combined for statistics. This represents the reality with better accuracy, since the basal conditioned media needs to be concentrated three times more, which results in more protein lost in the Amicon filter. Also C3 proteins secreted to the basal side can remain trapped inside the pores of the transwells18. Data represented as average ± SD (2-way ANOVA, *p < 0.05, **p < 0.01).
