title: Serologic relatedness between Thy-1.2 and actin revealed by monoclonal antibody.
abstract: Monoclonal antibodies with affinity for Thy-1.2 on thymocytes also can bind to actin within marsupial, murine, and human cells. A similar cross-reactivity between Thy-1.1 and vimentin was revealed by Dulbecco and co-workers employing monoclonals. A computer-assisted analysis of the amino acid composition provided suggestive evidence for the occurrence of sequence homology between Thy-1.1 or Thy-1.2, actin, and vimentin that likely accounts for the serologic relatedness detected by hybridoma antibodies.
