A SURVEY IS MADE OF THE IMMUNOCHEMICAL BEHAVIOR OF FOUR OF THE SIX KNOWN TYPES OF CRYPTOMONAD BILIPROTEINS: phycocyanins 612 and 645 and phycoerythrins 545 and 566. They were compared both among themselves and to selected biliproteins isolated from blue-green and red algae. All the cryptomonad biliproteins were shown to be closely related to each other by Ouchterlony double diffusion technics. An antigenic relationship among all the cryptomonad biliproteins and B-phycoerythrin (red alga) and C-phycoerythrin (blue-green alga) was established. Only a very marginal cross-reactivity was found between C-phycocyanin (blue-green algae) and the cryptomonad biliproteins. These results suggest a common ancestor for the photosynthetic units of all three biliprotein-containing phyla.
