Gene Information

General description

ABN90P is a Guinea Pig polyclonal version of the Anti-NeuN, clone A60 (MAB377), a highly characterized and cited mouse monoclonal antibody that specifically recognizes the DNA-binding, neuron-specific protein NeuN, which is present in most CNS and PNS neuronal cell types of all vertebrates tested. NeuN protein distributions are apparently restricted to neuronal nuclei, perikarya and some proximal neuronal processes in both fetal and adult brain although, some neurons fail to be recognized by NeuN at all ages: INL retinal cells, Cajal-Retzius cells, Purkinje cells, inferior olivary and dentate nucleus neurons, and sympathetic ganglion cells are some examples. Immunohistochemically detectable NeuN protein first appears at developmental timepoints that correspond with the withdrawal of the neuron from the cell cycle and/or with the initiation of terminal differentiation of the neuron. Immunoreactivity appears around E9.5 in the mouse neural tube and is extensive throughout the developing nervous system by E12.5. Strong nuclear staining suggests a nuclear regulatory protein function. No difference between protein isolated from purified nuclei and whole brain extract on immunoblots has been found.

Specificity

This antibody recognizes the N-terminus of NeuN.

Immunogen

Epitope: N-terminus
