. 2'7'-Dichlorofluorescein diacetate (DCFH-DA) was used to measure global ROS production as previously described .
aureus ATCC 6538 as determined in real-time fluorometry
NO imaging techniques primarily utilize magnetic resonance (MR), electron paramagnetic resonance (EPR) spectrometry, and fluorometry
. NO is a diatomic free radical that contains one unpaired electron derived from L-arginine via the catalytic action of NOS.

Therefore, calcein-AM only stains viable cells and provides both morphological and functional information of viable cells under microscopy and fluorometry
. In this experiment, calcein staining was performed as described .
The purified samples are ready for sensitive, quantitative analysis using either HPLC or direct fluorometry
Photosynthetic rates of Ulva (Chlorophyta) measured by pulse amplitude modulated (PAM) fluorometry
Salinity responses of halophytic and non-halophytic bryophytes determined by chlorophyll fluorometry
. Journal of Bryology, 31, 11-19.
Determination of ammonium ion by fluorometry
or spectrophotometry after on-line derivatization with o- phthalaldehyde.
Using the image analysis software that we have developed (Tsechpenakis et al., 2007, 2008), we could essentially quantify the plankton field for every centimeter of our tow, and we could match these data centimeter by centimeter with the corresponding environmental data collected by the onboard sensors (pressure [depth], temperature, salinity, and fluorometry
However, PAM fluorometry
was developed for higher plants and not envisioned for studying motile organisms.
The photoluminescence (PL) was measured on a Hitachi F-7000 Fluorometry
with a Xe lamp as the excitation light source at room temperature and the excitation wavelength of 310 nm.
