2021, Life SciencesCitation Excerpt :It was measured by enzyme-linked immunosorbent assay (ELISA) using mice specific ET-1 kit (Abcam, Cambridge, UK) according to the manufacturer's instructions. The intracellular H2S content of the lung tissue supernatant was assayed using the zinc precipitation method [29] that was further modified by Ang et al. [30]. In brief, each tissue sample was divided into 2 parts one part was homogenized in 50 mM sodium carbonate buffer, pH 9 (at pH 9 free sulfides would be retained in solution), and another one was homogenized in a 50 mM sodium phosphate buffer, pH 6.
Effects of mercury addition on microbial community composition and nitrate removal inside permeable reactive barriers
2018, Environmental PollutionCitation Excerpt :We measured NO3− via chemiluminescence on a Teledyne Technologies model T200 NOx analyzer (Thousand Oaks, CA, USA) according to Cox (1980). We measured ammonium and sulfide colorimetrically on a Shimadzu 1601 spectrophotometer (Kyoto, Japan) following the protocols of Strickland and Parsons and Gilboa-Garber (Strickland and Parsons, 1972; Gilboa-Garber, 1971), respectively. We measured DIC on an Apollo SciTech AS-C3 DIC analyzer (Newark, DE) according to Dickson (Dickson and Goyet, 1994).
