Fluo-2 MA is an ideal indicator for HTS and other calcium applications because of its easy loading, bright response, and lower cost compared to Fluo-3 and Fluo-4.
Fluo-2 MA (U.S. Patent No. 5,049,673) is the same molecule as Fluo-8.
TEFlabs is the lowest cost provider of Fluo-2 and Fluo-8 and can apply aggressive discounts to bulk or frequent orders.

Fluo-2 HA – High Affinty
Fluo-2 LA – Low Affinity
Fluo-2 LR- Leakage Resistant*
Fluo-2 NM- Near Membrane*
Fluo-2 Mito- Mitochondrial*
Fluo-2 Variant kd's:
Fluo-2 HA 230 nM
Fluo-2 MA 390 nM
Fluo-2 LA 6.9 uM
Fluo-2 LR 230 nM*
*These products are under development, such that the Kd's assigned to them are estimates based on similar product families (i.e. Fura-2, Fura-2 LA, and Fura-2 LR).
Currently Fluo-2 MA, Fluo-2 HA, and Fluo-2 LA are available and in stock; Fluo-2 NM,Fluo-2 LR, Fluo-2 MITO, and Fluo-2 MAG are still in production.
Leakage Resistant (LeakRes)
These modified indicators are retained in the cell for hours, with little to no change in the properties of their parent compounds. Numerous publications have emanated since their inception in 1994.
Teflabs is the sole manufacturer of the leakage resistant dyes Fura-2 LeakRes (Cat.#0108, formerly Fura-PE3), Indo-1 LeakRes (Cat.# 0144, formerly Indo-PE3), Fluo-2 LeakRes and Asante Calcium Red LeakRes (Cat.# 3150).
TEFLabs’ new fluorescent sodium ion indicator dye, Asante NaTRIUM Green, provides a usable Kd, visible wavelength response to sodium ions. With an excitation maximum near the 488 nm argon laser line Asante Natrium shows a nearly five- fold increase in green emission upon saturating with sodium.
Prices have been reduced for Indo-1.
Indo-1 AM 1mg – $90.00
