Structural changes in metallothionein isoforms revealed by capillary electrophoresis and Brdicka reaction

Original language description

Metallothionein (MT) as a potential cancer marker is at the center of interest and its properties, functions and behavior under various conditions is intensively studied. In the present study, two major mammalian MT isoforms (MT-1 and MT-2) were separated using capillary electrophoresis (CE) coupled with UV detector in order to describe their basic behavior. Under the optimized conditions, the separation of both isoforms was enabled as well as estimation of detection limits as subunits and units of ng per mL for MT-2 and MT-1, respectively. Further, the effects of thermal treatment and the presence of denaturing agent such as urea on MT-1 and MT-2 isoforms were studied by CE-UV. Thermal treatment caused an increase in the signals of both isoforms. A new parameter called precipitation rate has been defined based on this finding. This parameter can be expressed as a slope of the linear regression of the time dependency curve recalculated on the MT concentration. The thermal precipitation
