متن کاملExpression of Lewis(x), sialylated Lewis(x), Lewis(a), and sialylated Lewis(a) antigens in human lung carcinoma.
One hundred and five cases of various human lung neoplasms were studied immunohistochemically using monoclonal antibodies recognizing the antigens, Le(x), sialylated Le(x) (SLEX), Le(a), and sialylated Le(a) (SLEA). Of the 92 lung cancers examined for antigen expression SLEX was detected in 57% (52 cases), Le(x) in 42% (39), SLEA in 36% (33), and Le(a) in 23% (21). None of these antigens were e...
