The phrase "a charged reagent" is correct and usable in written English.
It can be used in scientific contexts, particularly in chemistry, to refer to a reagent that carries an electric charge, which can affect its reactivity and interactions.
Example: "In this experiment, we will use a charged reagent to facilitate the reaction between the two compounds."
Alternatives: "an ionized reagent" or "an electrically charged reagent".
Due to the positive charge by means of new functional groups generated on p 4-VP -based p 4-VP -basedmodification, the absorp 4-VP -basedsitely charged reagents such as fluorescein sodium salt (FSS) was increased drastically.
This technique relies on tagging sterols with the Girard P reagent to introduce a charged quaternary ammonium group.
Have a charged cellphone.
Bring a charged electronic game.
The G22C MscL mutant was incorporated in fluorophore-filled vesicles and the channels were activated by adding the positively charged sulfhydryl reagent [2- trimethylammonium)ethyl] methanethiosulfonate bromide (MTSET), which reacts with Cys22 and thereby weakens the gate—allowing for channel activation without applied tension.
In the model, it seems most likely that the conserved lysine residues contribute to binding of the phosphate of ATP as cysteine mutants of these residues show that ATP potency can be increased by positively charged MTS reagents and reduced by negatively charged MTS reagents (Roberts and Evans, 2007; Roberts et al., 2008).
The accessibility of the 20 engineered cysteines to polar charged sulfhydryl reagents was studied in the absence and presence of cocaine or dopamine.
Using charged MTS reagents and Ag+ ions as probes acting on Cys residues engineered in the pore lumen, we found that the S6 transmembrane helices of KCa3.1 cannot form a pore constriction tight enough to prevent ion flow for channels in the closed state.
In most cases, both the functional effects of modification and the rate of modification were similar for negatively and positively charged MTS reagents.
However, at P2X1 receptors, Phe291Cys was inhibited by both positive and negatively charged MTS reagents demonstrating accessibility and suggesting that it contributes to the ATP binding pocket.
