WebThe excess thiol-blocking agent (NEM) must be removed in order to prevent any competition for the labeling reaction. This can be done by various techniques of protein precipitation (TCA, EtOH, acetone, etc.) or size-exclusion column chromatography (also possibly dialysis). 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 …
