Minute™ Synaptosome Isolation Kit
The ability to isolate synaptosomes from neuronal tissues/cultured cells is essential for understanding the
mechanisms of neurological diseases. Contained in synaptosomes are synaptic vesicles with diameters of
80-200 nm that play an important role in signal transmission. Traditionally, synaptosomes are isolated by
density ultracentrifugation. The procedure is relatively tedious and time-consuming. A larger amountof
starting material is usually required. MinuteTM synaptosome isolation kit provides a simple and rapid method
for isolating synaptosomes from fresh/frozen neuronal tissues/cultured cells. The protocol can be completed
in less than 1 h without using Dounce homogenizer and ultracentrifugation. The amount of starting material
required (10-50 mg tissue) is only a fraction of that required by the traditional method. The buffers used are
detergent-free and synaptosome associated proteins are isolated in native form.
