Nem thiol blocking
WebSep 18, 2013 · As a result of the reactivity of thiol-blocking electrophiles with both -SOH itself and the 1,3-dicarbonyl probes used for its labeling, ... Blocking was achieved using NEM (20 m m) in 2.5% SDS, 25 m m HEPES, 1 m m DTPA (diethylene triamine pentaacetic acid, pH 7.7) for 20 min at 50 °C, followed by a cold acetone precipitation. WebNEM and p-BPI increased the non-specific binding of T4 and completely abolished specific binding. All these agents blocked the specific binding of T3. These results demonstrate that T3 and T4 binding sites in the liver nuclei may not be altogether identical and that the different effects of -SH blocking agents on the binding of T3 and T4 is probably …
