[Electrophoretic examination of protein distribution in guinea pig perilymph].

Perilymph and serum of guinea pigs were investigated using immunoelectrophoresis and polyacrylamide gel electrophoresis. The molecular weights of the perilymph proteins were estimated by electrophoresis in a linear polyacrylamide gel gradient (3-20%). The immunoelectropherograms and the polyacrylamide gel electropherograms of equivalent amounts of perilymph protein and serum protein are nearly the same. The immunological detection of the perilymph proteins indicates that they are serum proteins. The clear identification of the individual proteins fails because of missing monospecific antisera against the individual proteins of guinea pig. High-molecular proteins (range of the molecular weight estimation 67 000-290 000) are also detectable in the perilymph according to the molecular weight estimation.
