pH Lemon LC3B

pH-Lemon – LC3B targets the pH probe into autophagosomes and lysosomes. The construct can be used to image pH variations within these particular vesicles and might, hence, well report the autophagic activity of single cells. The pKa of the probes is appr. 6.7. CFP should be excited at 430 nm and emission can be collected at 480 nm and 535 nm (FRET channel). Alternatively, the pH sensitive YFP can be excited directly using 480 nm illumination light.
