Alexa Fluor® 647 anti-RBFOX3 (NeuN) Antibody, RBFOX3, W18230A,BioLegend,608454

RBFox3, commonly referred to as NeuN, is one of a family of 3 mammalian Fox homologues. Fox was discovered in C.elegansas a gene involved in sex determination, and the name RBFox is an acronym of "Feminizing locus on X". The Fox protein and its 3 mammalian homologues are all about 46 kD proteins, each of which includes a central highly conserved RRM type RNA recognition motif, which corresponds to a small ~70 amino acid structure consisting of 4 beta strands and two alpha-helices. RBFox3 is a protein which has a function in RNA splicing and is expressed heavily and specifically in neuronal nuclei. The antibody reveals strong nuclear and distal cytoplasmic staining for RBFox3/NeuN and the complete absence of staining of astrocytes and other kinds of non-neuronal cells. This RBFox3/NeuN antibody is therefore an excellent marker of neuronal cells.
