A number of ELISA Kits are available that target NOGO C, an alias of the protein, reticulon 4. The human protein is encoded by the gene RTN4. The protein's cellular localization is indicated to be membrane-associated. Additional synonyms or past names for this protein may include: ASY, NI220/250, NOGO, NSP, NSP-CL, Nbla00271, Nbla10545, RTN-X, RTN4-A, RTN4-B1, RTN4-B2, RTN4-C. Homology is conserved in other species, such as Mouse, Rat, Zebrafish, Frog.
