5-(And-6)-Carboxyfluorescein
5-(and-6)-FAM (full name: 5-(and-6)-Carboxyfluorescein mixed isomer) has a pKa of 6.5 and can be used as a pH indicator. Its excitation spectrum and fluorescence response to pH are similar to those of BCECF. Carboxyfluorescein can also be used as a tracer dye. The dye is membrane-impermeant and can be loaded into cells by microinjection or scrape loading. </p> <ul> </p> <li> lamba;<sub>Ex</sub>/ lamba;<sub>Em</sub> (pH 9) = 492/514 nm</li> </p> <li> epsilon; (pH 9) = 82,000</li> </p> <li>Yellow orange solid soluble in pH gt;6 water</li> </p> <li>Store at 4°C and protect from light, especially in solution</li> </p> <li>C<sub>21</sub>H<sub>12</sub>O<sub>7</sub></li> </p> <li>MW: 376</li> </p> <li>[72088-94-9]</li> </p> </ul>
