title: Presence of specific binding sites for [3H]sarcophytol-A in cultured human skin fibroblasts.
abstract: The presence of specific binding sites for [3H]sarcophytol-A in human skin fibroblasts was examined using biochemical and morphological methods. The displacement studies clearly revealed that high (KD = 31.0 nM) and low (KD = 6.05 microM) affinity sites were present in the intact cells. Moreover, autoradiographic studies using light microscopy revealed that the specific binding sites may exist in both the cytoplasm and the nuclei.
