The membrane fractions were used in the assay for the specific binding of 125I-[Sar1, Ile8]Ang II. The percentage of ARB dissociated from the AT1 receptor was calculated by the following formula: 100À((specific binding using cell membrane without ARB treatment with no wash-out)À(...
Phosphorus Triiodide is an unstable inorganic chemical compound with the formula PI3. it BYJU'S to understand the properties, structure and its uses.
Fresh leaves were weighed (FW) and in turn, immersed in water overnight to weigh the water-saturated weight (SW), followed by 24 h of drying at 80 °C for weighing the dry weight (DW). The RWC was calculated based on the formula (FW − DW)/(SW − DW) × 100. The ...

Salvianolic Acid B (Sal B) is a water-soluble component from Danshen (a traditional Chinese herb widely used for chronic renal diseases) with anti-oxidative and cell protective properties. Sal B also has potential protective effects on renal diseases. Tubular epithelial cells can undergo epithelial...
The compounds are used as anti-static agents for polymers.ALSO:Fibres and fabrics are rendered antistatic by immersing them into an aqueous solution or an organic solution of quaternary ammonium salts of the general formula in which Ha is chlorine or iodine, R1 is an aliphatic hydrocarbon ...
The expression levels of the mutant hMC3Rs were calculated as the percentage of WT hMC3R expression using the formula: (mutant – pcDNA3.1)/(WT – pcDNA3.1)×100%, where the pcDNA3.1 were used as control for background staining (Wang et al. 2008, Yang & Tao 2012). Ligand binding ...
