    Abstract:
    A monoclonal antibody (MAb) specific for rainbow trout thrombocytes was produced and its reactivity was demonstrated by flow cytometry and immuno-electron microscopy. Flow cytometry analysis showed that this MAb (TTL-7D11) reacted positively with about 30% of the peripheral blood leucocytes (PBL) and about 1%, 2%, and 11% of the pronephros, mesonephros, and spleen cells, respectively. Electron microscopy using immunogold labeling demonstrated that this MAb reacted strongly with thrombocytes, where gold beads could be seen attached only to the membrane and canalicular system of these cells. Positive and negative leucocytes for this MAb were obtained by magnetic cell separation. In the positive fraction, 96% of the cells were thrombocytes, while in the negative fraction no more than 3% were, which clearly showed a high purity of the positive fraction. Aggregation studies showed that about 75% of the positive fraction cells aggregated after being mixed with U-46619 thromboxane-mimetic, whereas in the negative fraction only 10% of the cells did so. Thus, utilizing the TTL-7D11 we have succeeded in isolating a pure thrombocyte population, and this would facilitate further studies, particularly on their characteristics and function(s).
