Description:
Lectins, carbohydrate-binding glycoproteins that cause agglutination of homologous particles, were found in the mucus and fluid from the mantel (pallial) cavity of eastern oysters Crassostrea virginica. ccurrence in mantle cavity fluid was probably due to dissociation from mucus on the external surfaces of organs. epeated washes of the mantle cavity reduced agglutination titers for bacterial isolates and vertebrate erythrocytes (RCBs), but activity was partially recovered after 2 hours at 23 degrees C. iters of mantle cavity lectins for different RBCs were highly and positively correlated, indicating a strong interdependence regardless of specificity. ositive correlation between titers of mantle cavity lectins (for different RBCs) and titers of hemolymph lectins from the same oysters imply a common source. pecificity of lectins from isolated and homogenized organs (mantle, gill, digestive gland and adductor muscle) was similar to lectins from mantle cavity fluid. solated mantle and gill tissues made the most lectin activity in homogenates, whereas the adductor muscle made the least contribution in both cases.
