31. Fluorescein angiography showed lower leakage from the CNV in UDCA and TUDCA treated groups than the control group.32. Cells that are labeled with fluorescein isothiocyanate-dextran ( FDX ) can be selectively photoablated by fluorescent excitation. 33. These infrared frequencies penetrate retinal layers, allowing ICG angiography to image deeper patterns of circulation than fluorescein angiography. 34. The water at Aachtopf was described as " gorgeously green lit " by the fluorescein and tasting of creosote. 35. Fluorescein can also be conjugated to nucleoside triphosphates and incorporated into a FISH, or targeted by antibodies using immunohistochemistry.36. The tear breakup time can be determined after placing a drop of fluorescein in the cul-de-sac. 37. The fluorescein dye also reappears in the patient urine, causing the urine to appear darker, and sometimes orange. 38. The standard would be fluorescein in NaOH, typical values for a high end instrument are in the femtomolar range. 39. The degeneration ( or decomposition ) of fluorescein is measured as the presence of the antioxidant slows the fluorescence decay. 40. It forms the core structure for various chemicals, most notably fluorone dyes, including fluorescein , erythrosine and rhodamine.
