Abstract

Hemocytes were fractionated by centrifugation on a discontinuous Percoll densitygradient from the hemolymph of Phallusia mamillata. Results obtained from microcultures of thefractionated hemocytes, sugar-inhibition experiments, SDS-PAGE, and immunoblotting indicate that"compartment cells" release cellular-type (CL) lectins that are specific for a-lactose and lactulose.The released lectins have the same properties as the CL lectins that were previously isolated fromsonicated unfractionated hemocytes, but they differ in terms of some molecular and immunologicalproperties from the lectins (SL) purified from the serum. SLs were never found in the supernatantsfrom microcultures ofthe fractionated hemocytes.
