This uneven distribution is in accordance with the accumulation of neurotransmitters in the axon for information delivery. dendrite cell, AcD) and an AIS either located directly at the origin of the. Higher levels of pyroglutamic acid and glutamic acid are revealed in the axon compared to in the body and dendrite. thickness between 3 m and 18 m, were spaced by 0.5 m. The ionization efficiency from the nano-capillary is enhanced to guarantee mass spectrometric analysis of multiple components from the axon and dendrite. The key is the insertion of a ∼130 nm capillary tip into one axon or dendrite to load the cytosol through electro-osmotic flow. H zone: thick filament (myosin) only I band: thin filament (actin) only. Here, electrosyringe-assisted electrospray mass spectrometry (MS) is established for the first time to achieve intracellular sampling from one axon or dendrite in living neurons for mass spectrometric analysis. Slide 1 Diagram of a Neuron Terms to Know: Dendrite Cell body Nucleus Axon Schwann Cell Myelin Sheath Node of Ranvier dendrite Myelin sheath axon Cell body Nodes of Ranvier. The molecular profiling of single axons and dendrites in living neurons could provide important information for the better understanding of neuron function.
