| Annotation description: | Figure 1D: Quantitative analysis of synaptotagmin 1 immunogold labeling over presynaptic terminal cytoplasm at synapses in the hippocampus of synaptotagmin 1 KO and WT mice. Figure 2A: Ultrastructural examination by immunogold EM show SYT1 localization to the presynaptic cytosol, presynaptic active zone, PSD, postsynaptic cytosol and the postsynaptic membrane (quantified in figure 3) Figure 2B: Ultrastructural examination by immunogold EM shows association of SYT1 to postsynaptic vesicles. Figure 2D-I: confirmation of postsynaptic localization of SYT1 with IF on dissociated hippocampal culture, co-staining with PSD95. |
