that these proteins are immunologically related , but are unrelated to other biliproteins , is reminiscent of previous immunological studies of biliproteins which showed that while the three major spectroscopically distinct classes of biliproteins ( phycoerythrin , phycocyanin , and allophycocyanin ) shared no common antigenic determinants , there was a strong antigenic determinant to specific biliprotein classes which crossed taxonomic divisions .
