Phalloidin-AMCA conjugate is a blue fluorophore that specifically labels filamentous actin (F-actin). It consists of aminomethylcoumarin (AMCA; ex em max = 350 450 nm) conjugated with phalloidin , a mycotoxin that binds F-actin. Phalloidin-AMCA conjugate is used in fixed and permeabilized tissue sections, cell cultures, or cell-free experiments.
Indo-1 (potassium salt) is a ratiometric fluorescent calcium indicator. It is ideal for analyses using flow cytometry, as it uses a single excitation source, typically 349-364 nm light from an argon-ion laser. The emission maximum shifts from 475-485 nm without calcium to 400-410 nm when Indo-1 (potassium salt) binds calcium. Indo-1 (potassium salt) is prone to photobleaching, which limits its usefulness in methods involving microscopy.
DPPP is a probe that reacts stoichiometrically with hydroperoxides to yield the fluorescent molecule diphenyl-1-pyrenylphosphine oxide (DPPP-O). Plasma levels of lipid hydroperoxides of phosphatidylcholine, phosphatidylethanolamine, triglycerides, and cholesteryl esters have been measured by HPLC with a post column detection system using DPPP. DPPP has also been used as a fluorescent probe for the detection of low density lipoprotein and cellular oxidation. Fluorescence of DPPP-O can be monitor using excitation and emission wavelengths of 351 nm and 380 nm, respectively.
The amine-reactive AMCA, SE (7-amino-4-methylcoumarin-3-acetic acid, succinimidyl ester) and its conjugates yield blue-fluorescence (approximate excitation emission maxima ~353 442) that can be used as a contrasting color in multicolor applications.
