Macromolecules in the receptor lymph of campaniform sensilla.
The receptor lymph of campaniform sensilla on the halteres of the blowfly, Calliphora vicina, was analyzed histochemically. Acid mucopolysaccharides were demonstrated by a test for iron-binding capacity (Hale-reaction). Further characterization by enzyme treatment showed that the receptor lymph contains hyaluronic acid and/or chondroitin sulfate. Ultrahistochemical studies gave evidence for glycoproteins in the inner and outer receptor lymph space. The significance of acid mucopolysaccharides for arthropod sensilla is discussed.
