a Gel electrophoresis (SDS–PAGE) of the purification fraction of GFP-fused AqpZ. The band in the red dash box displays purified GFP-fused AqpZ (size of ~70 kDa). b microscopic image of AqpZ expression. c DLS intensity graph of size analysis of liposomes and AqpZ liposomes. d Zeta potential of liposomes and AqpZ liposomes. e Stopped flow analysis of liposomes and AqpZ liposomes with rate constants. The inset graph shows the calculated permeability of liposomes and AqpZ liposomes. The readings are based on at least three experiments. The scale bar in (b) is 5 μm. The error bar represents the standard deviation (s.d.).
