Inx2 protein in the antennal nerve.
Antennal nerve of a wild type animal stained to detect Inx2 using a rabbit polyclonal anti-Inx2 primary antibody and anti-rabbit FITC-conjugated secondary antibody. The antennal nerve is primarily populated by sensory afferents emanating from antennal olfactory sensillae. Spots of Inx2 are present in a linear arrangement along its length. Whether they are neuronal or glial in nature has not been explored. In many tissues, eg. salivary gland cells and in brain glia, wherever Inx2 is detected we have also found Inx3 (Inx3 in the adult brain) and Ogre (Ogre in the adult brain). We would expect this to be the case in the antennal nerve also, especially if the staining in the image above represents glia.
