WormMine: ExpressionPattern Expr2969

• Pattern: Immunofluorescence microscopy of wild-type hermaphrodites using anti-IDA-1 antibodies revealed strong immunoreactivity within the pharyngeal nerve ring, around the vulva and the tail, and variable staining at the nose tip. Males showed weaker staining of the nerve ring and intense staining of male-specific tail neurons. Immuno-reactivity was detectable from the L1 larval stage onwards. The observed cellular expression pattern matches that of a transcriptional pida-1::GFP reporter construct (see Expr843).
• Primary Identifier: Expr2969
• Subcellular Localization: At the subcellular level, the antigen was localized to cell bodies exterior to the nucleus and to neuronal processes. These included amphid sensory dendrites, ALA lateral processes, processes of the ventral and dorsal nerve cords and PHC neurons in the tail spike. Staining along the processes was punctate in appearance and distributed among a large number of small individual elements and a few brighter, apparently larger objects.
