Compared to PSD fraction, it can be possible to identify the synaptic protein acting on the immature synapse around the dendritic filopodia-rich fraction. We used live neuron to induce phagocytic cap formation. The main advantage of this technique

In this protocol, we introduce a method for purifying the dendritic filopodia-rich fraction from the phagocytic cup-like protrusion structure on cultured hippocampal neurons by taking advantage of the specific and strong affinity between a dendritic filopodial adhesion molecule, TLCN, and an extracellular matrix molecule, vitronectin.
