Annotation description:	NCS-1 immunoreactivity at the Calyx of Held synapse. Figure 3a shows a prominent immunofluorescence signal for NCS-1 at the presynaptic compartment for calyx of Held synapses, that partially colocalizes with staining against the presynaptic marker Syntaxin (it is not mentioned which isoform). Figure 3b evaluates the antibody specificity (since a KO control is missing): Pretreatment of the NCS-1 antibody with recombinant NCS-1 leads to no NCS-1 immunofluorescence, but has no effect on the syntaxin signal. 30/5/2017 Pim: - Literal: " NCS-1 immunofluorescence signal (green, left) and syntaxin immunofluorescence signal (red, center) partially overlapped (yellow, right), indicating that NCS-1 is expressed in both the presynaptic and postsynaptic compartments."
