Spectrophotometric and fluorometric
detections usually require
Using a 3-mm punch from an identical DBS and the previous fluorometric
LAL assay with and without Lalistat-2 (5), we obtained a specific activity of 466 [micro]mol/h/L (within the range of values reported previously) for the LAL component, which is 1.9-fold lower than the activity measured with the new UPLC-MS/MS assay.
In conclusion, we established that the copolymers containing boronic acid and pyrene units can be utilized for the fluorometric
sensing of [H.sub.2][O.sub.2].
Activities of caspase-8 and -9 were determined using fluorometric
In the fluorometric
assay the highly sensitive AR/HRP system has been used for assessment of [H.sub.2][O.sub.2] production by recording changes in resorufin fluorescence .
Due to the lower sensitivity of this method (limit of detection of 2 [micro]g/kg) the samples that were collected in 2009 were analyzed using the VICAM AflaTest[R] immunoaffinity fluorometric
method  (limit of detection of 1 [micro]g/kg) that quantifies total aflatoxin (B1+B2+G1+G2) concentrations using AflaTest[R] Fluorometer Series-4.
deoxyribonucleic acid-deoxyribonucleic acid hybridization in microdilution wells as an alternative to membrane filter hybridizationin which radioisotopes are used to determine genetic relatednessamong bacterial strains.
assay for hydroxyl radical prevention capacity using fluorescein as the probe.
From conserved tissue biopsies we determined the levels of malondialdehyde (MDA) as a marker for OS and glutathione (GSH) as a marker of defense antioxidant mechanism, using the fluorometric
methods according to Conti et al.
As a chemodosimeter, AQCD showed high selectivity toward [Cu.sup.2+] over other competitive cations in aspects of colorimetric and fluorometric
In this paper, we report the construction of a fluorometric
whole cell-based biosensor using A.
The concentration of 4-hydroxynonenal (4-HNE), a marker of oxidative stress, was assayed as a fluorometric
derivative with 1, 3cyclohexandione (CHD) separated on RP [C.sub.18] column by HPLC with spectrofluorometric detection (excitation [lambda] = 380 nm, emission X = 445 nm) .
