Are CF® dyes sensitive to pH?

CF® dyes are chemically stable within the pH range of at least 2 –11. The fluorescence of most CF® dyes is relatively insensitive to pH, except for that of CF®405M, CF®568, CF®620R, and CF®633. The fluorescence of these four CF® dyes becomes weaker when pH drops below 4.5.
