The other antibodies in this assay did not hinder the interaction of TC with Cbl at all (Table 3) and therefore we cannot draw any conclusions on the involvement of the other parts of TC ... In this case, the lack of binding to the reduced TC is caused rather by loss of the correct three-dimen- sional organization than by disruption of the S-S bond...
