Polyclonal antibodies marking the radial nerve cells in the starfish Asterias amurensis

The results of preliminary studies suggest that the cytoskeletal fraction o f the radial nerve of the starfish Asterias amurensis contained a 32 kDa pr otein, which is tissue specific, This protein was isolated from the radial nerve by preparative electrophoresis and used as an antigen for raising pol yclonal antibodies. When testing these antibodies on sections of the starfi sh tissues, it was shown that they interact only with the proteins, present in the radial nerve cells. A conclusion was drawn that the raised antibodi es may be used as a cell marker when studying regeneration of the nervous s ystem in starfish.
