Immunodetection of haemocyte subpopulations by N-acetylmuramic acid antibody in Planorbarius corneus (L.) (Gastropoda, Pulmonata).

The cell subpopulations in the haemolymph ofPlanorbarius corneus were distinguished by means of flow cytometry. An antibody againstn-acetylmuramic acid was prepared and used as a cellular marker to recognize the cell types forming the subpopulations. The spreading haemocytes showed a positive reaction for anti-n-acetylmuramic acid; round haemocytes gave a negative reaction.
