(A) Drift velocity measurements of ortho-Texas Red DHPE (red curve) and para-Texas Red DHPE (black curve) in 1 mM phosphate buffer with 5 mM NaCl at different pH values. (B) Shows the calculated charge values for both ortho- and para-Texas DHPE using the measurements in (A), the diffusion values from FRAP data and Eq. 12.
