    Abstract:
    SDS-polyacrylamide gel electrophoresis and immunoblot were applied to analysis of plasma proteins immunologically related to inter-alpha-trypsin inhibitor (ITI). In this system, anti-ITI sera were able to identify ITI and other components with an Mr near 120 kDa which would be degradation products of ITI by limited proteolysis. An anti-UTI (urinary trypsin-inhibitor) serum could detect, beside these derivatives, two minor components (Mr values near 90 and 60 kDa). Analysis of perchloric acid supernatants of plasma samples, using the same technic, induced visualization of a new component, similar to urinary trypsin inhibitor which could not be detected by direct analysis. This one was also characterized in a higher content in pathological samples (renal failure and infectious diseases).
