The comparison of confocal microscopy images after intracellular uptake of tracer molecules in cell-wall-deficient mutant C. reinhardtii through electroporation using (a) microstructure, (b) commercialized cuvette when 1 kV cm−1 and 45 ms pulse was applied.
The red color indicates the chlorophyll of algal cell. Scale bar means 10 μm.
