Neurons are specialized cells of the nervous system designed to transmit chemical and electrical signals throughout the body. A biological marker is an indicator of a biological state. Often times it may be difficult to take biopsy or living tissue sample for medical diagnostics or scientific research purposes. Neuronal markers make it easier to look into the nervous system. Neuronal markers are present in the brain and peripheral nervous system and are indicative of certain neuronal diseases, statuses, or conditions. Neuronal markers are typically very effective diagnostic or prognostic tools in the treatment of sickness. These biomarkers can also be used to identify neural cells or detect expression details of certain types of molecules. Neuron markers sold by Abcore Inc. can be categorized into axon markers, dendrite markers, growth cone markers, soma markers, and synapse markers. A synapse is a junction across which a nerve impulse passes from an axon terminal to a neuron, muscle cell, or gland cell. The space allows the impulse to pass using messengers like neurotransmitters and/or organelles. The electrical impulse from the neuron sending the signal triggers this migration of neurotransmitters or other molecules.

Anti-SV2A antibody binds against the target synaptic vesicle protein 2a. SV2A is localized in the cytoplasmic vesicle, secretory vesicle, and the synaptic vesicle. It is a multi-pass membrane protein that is an integral membrane glycoprotein in all synaptic vesicles. Anti-SAP97 antibody binds against the target protein synapse associated protein 97. Synapse associated protein 97 is localized on the cell membrane and in the cell junction or synapse. It is abundantly expressed in atrial myocardium, lung fibroblasts, cervical epithelial cells, and B cells. SAP97 is an essential multi-domain scaffolding protein required for normal development.
