the specific reactivity of the polyclonal antiserum confirms the identity of the 48k5 clone and further distinguishes the 48- and the 90-kda core proteins , which do share the 6g12-defined epitope and at least one additional antigenic determinant with the 48k5 cdna-encoded protein , from the 125- , 64- , and 35-kda core proteins of cell surface hspg of human lung fibroblasts which do not react with either antibody preparation .
