Abstract

Peanut agglutinin (PNA) was known for its selective binding to cone cells. In the present study, we investigated whether there was any difference in PNA binding among various subtypes of cone photoreceptor cells in the dace retina. The outer segments of the long-double- and long-single-cone cells were preferentially labeled with PNA. Ultrastructural pre-embedding labeling revealed that the binding sites of PNA were confined to the calycal processes of these cells. By contrast, only slight labeling was discerned on the corresponding regions of other types of cone cells. The results indicate that PNA can distinguish the long-wavelength-sensitive cone from the short-to-middle-wavelength-sensitive cone cells.
