WormMine: ExpressionPattern Expr1233

• Pattern: kel-1 protein became detectable at the 1.5-fold embryo, appearing as a dotted line at the midline of the head region. At the 2-fold embryo, and 3-fold embryo, observed more evidently as a central line along the lumen of the pharynx between posterior end of the buccal cavity and the terminal bulb. At embryonic stages up to the pretzel, but not larval stages, anti-KEL-1 stained a structure appearing to be perpendicular to the pharynx. With laser scanning confocal microscope, this structure appeared to be a ring surrounding the posterior metacorpus. Expression was observed along the pharyngeal lumen throughout the postembryonic development. Cells strongly express KEL-1 were the pharyngeal g1 gland cells.
• Primary Identifier: Expr1233
• Remark: GFP and antibody show the same expression pattern.
