| pubmed-article:6255563 | pubmed:abstractText | A fluorescent derivative of the thyroid hormone 3,3'-triiodo-L-thyronine binds to cultured mouse fibroblasts; such binding is saturable. Video intensification fluorescence microscopy indicates that binding occurs at the plasma membrane. Diffusion coefficients, obtained by fluorescence photobleaching recovery, are consistent with binding to a protein receptor on the cell surface. | lld:pubmed |
