生物活性

Msr-blue is a first turn-on fluorescent probe for methionine sulfoxide reductase with a more than 100-fold fluorescence increment. Msr-blue is used for monitoring the enzyme activity in live cells (λex=340 nm, λem=440 nm)[1].

体外研究
(In Vitro)

Msr-blue is emited blue fluorescence after activation by methionine sulfoxide reductase A (Msr A). Msr-blue responded to Msr A in both a time- and dose-dependent manner, and more than a 100-fold increase in the emission is observed. Msr-blue is converted to its corresponding sulfide (15′) under catalysis by either the purified Msr A or a cell lysate[1].
The 6-OHDA-treated PC12 cells as a cellular model of Parkinson’s disease (PD) is employed and applied Msr-blue to probe the function of Msrs in the cells. With the aid of Msr-blue, a decline of the Msr activity in a PD model was disclosed for the first time[1].

生物活性

Msr-Ratio (Msr-green) is a ratiometric fluorescent probe of methionine sulfoxide reductase (λex=375 nm, λem=550 nm). Msr-Ratio is used for monitoring the enzyme activity in vitro and in live cells[1].

体外研究
(In Vitro)

Msr-Ratio is converted to its corresponding sulfide form by methionine sulfoxide reductase. Msr-Ratio displays favorable properties such as a nearly 400-fold fluorescence change, fast response rate (<30 min), large stokes shift (120 nm), and green emission (550 nm)[1].
There is a very weak background signal in live HL60 cells after the addition of Msr-Ratio. As the Msr-Ratio (10 μM) incubation time increased in cells from 0 to 8 h, the fluorescence signal constantly strengthened[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
