Unlike other hydrophobic dyes, TEFLabs near membrane dyes have a piperazine collar to latch the dye into the membrane, leaving the chelating portion to measure calcium in the gates. Our near-membrane UV-excitable indicators Fura-2 NearMem (formerly FFP-18) , and Indo-1 NearMem (formerly FIP-18), have enjoyed considerable success for their applications, because unlike other hydrophobic indicators, they do not get lost in the membrane.
Indo-1 is also available in High Affinity (Indo-1), Low Affinity (Indo-1 LowAff), and Leakage Resistant (Indo-1 LeakRes) versions.
