Annotated paper:Felmy F, et al. "Developmental expression of the Ca2+-binding proteins calretinin and parvalbumin at the calyx of Held of rats and mice" Eur J Neurosci. 2004 Sep;20(6):1473-82 PMID:15355314
Figure(s):Figure 6
Annotation description:The paper is describing the expression pattern of Ca2+ binding proteins in the calyx of Held synapse using conventional immunostaining. The calyx of Held is a giant synapse where a clear separation of can be made between the pre and postsynaptic compartments using standard confocal microscopy.
Figure 6 describes the results of a double immuostaining for Rab3 (a presynaptic marker) and calbindin. The staining for calbindin is restricted to the postsynaptic compartment, diffused (Fig. 6A), and does not co-localize with the Rab3 staining (Figure 6B,C).

Cytosolic localization is inferred from the diffuse staining of the protein.
