100 µg purified IgG, lyophilized. Albumin and azide were added for stabilization. For reconstitution add 100 µl H2O to get a 1mg/ml solution in PBS. Then aliquot and store at -20°C to -80°C until use. Antibodies should be stored at +4°C when still lyophilized. Do not freeze! |

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 (synapsin1a and synapsin1b). 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 hippocampus.
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.
