Carboxy SNARF 1
Description
Carboxy SNARF® 1 is a cell-impermeant pH indicator dye. The pKa of ~7.5 makes it useful for measuring pH in the range of pH 7 to pH 8. The emission shifts from yellow-orange at low pH to deep red fluorescence at high pH. Ratiometric fluorometry, therefore, is applied at two emission wavelengths,such as 580 nm and 640 nm.
