Cat. No. 106 011AbRED |
100 µg purified IgG, lyophilized, fluorescence-labeled with abberior STAR RED.
abberior STAR® dyes have been especially developed for for Stimulated Emission Depletion (STED) microscopy which allows higher resolution imaging compared to confocal laser scanning microscopy. For many of the fluorescence labeled antibodies conjugated to abberior STAR® dyes established fluorescence detection systems can be used. This product or portions thereof is manufactured under license from abberior GmbH. Reconstitute immediately upon receipt! Avoid bright light when working with the antibody to minimize photo bleeching of the fluorescent dye. |

Synapsins are neuron-specific phosphoproteins that are exclusively associated with small synaptic vesicles, with little or no expression in other tissues including neuroendocrine cells. In mammals, three distinct synapsin genes (synapsin1, 2, and 3) encode more than eight neuronal isoforms.
Synapsin1 is one of the most specific markers of synapses throughout the central and peripheral nervous system. In addition to synaptic nerve terminals, the protein is also present in certain sensory nerve endings. It is expressed in two splice variants (synapsin 1a and synapsin 1b). Synapsin1 interacts with vesicle membranes as well as with actin and spectrin.
Synapsin2 is expressed in the nervous system and also two splice variants were described so far, while synapsin3 shows a more restricted expression pattern and is mainly found in the hypocampus.
Synapsins are major phosphoproteins and are substrates for several protein kinases such as PKA, CaMK I and CaMK II. Synapsin1 is widely used as reference substrate for calmodulin-dependent protein kinases.
