Description
filaments in growing primary sensory and motor neurons. In the original paper for E1.9 [PMID: 2300585], the immunogen was described as rat E12, but the subsequent paper from the same authors and in the Depositor's notes it was described as mouse E11. The E1.9 epitope is developmentally regulated. E1.9 recognizes a cytoplasmic epitope in the primary sensory and motor neurons during axonal outgrowth, appearing at E8.5 and disappearing by E12 in the mouse when the same cell populations become positive for mAb B10. It stains neural crest-derived sensory neurons (e.g., neurons of dorsal root ganglia) as well as placode-derived sensory neurons (e.g.neurons of cranial nerves VII and VIII). It is not clear which filaments are recognized by this antibody. For this reason we didn't link it to a Uniprot or gene ID. See mAb B10 for a related antibody.
