Lectin has been played a key innate immune parameter in invertebrate host defense. Previously, we reported a novel sialic acid specific lectin (MC-sialec) cloned from EST sequence of Manila clam hemocytes infected with Perkinsus olseni. The lectin was expressed in E. coli M 15 and purified by Ni-NTA His binding resin matrix for antibody production. Lectin specific antibody was raised in mice. The presence of this lectin in different tissues of Perkinsus infected manila clam was studied by both Real Time-PCR and immunohistochemical localization assay. The results showed that upon infection, expression of MC-sialec was induced and expressed in foot, gill, adductor, mantle, hemocyte, stomach, intestine and digestive gland, siphon, palp and female gonad. Vibrio Tapetis infection induced expression of MC-sialec in hemocytes.
