Function of 2A peptide in various adult tissues. Sections through the heart (A, A'), lung (B, B'), liver (C, C'), kidney (D, D') and intestine (E, E') of adult CAG-TAG1 and CAG-TAG2 transgenic mice. The enhanced green fluorescent protein signal is depicted in green and TdTomato signal is depicted in magenta. No overlap of the H2B-GFP and Myr-TdTomato signal is seen, demonstrating efficient functioning of the 2A peptide. The scale bar in (A) represents 20 μm and is applicable to all panels.
