A structurally correlated series of cell-permeant thiophene fluorophores, characterized by intense green or red fluorescence inside live mouse embryonic fibroblasts, was developed. The fluorophores displayed rapid internalization, excellent retention inside the cells, and high optical stability in the cytosolic environment and did not alter cell viability and reproducibility. Depending on the molecular structure, they experienced distinct fate inside the cells: from bright and lasting staining of the cytoplasm to selective tagging of a small set of globular proteins.
开发了一系列结构相关的细胞渗透性噻吩荧光团,其特征是活体小鼠胚胎成纤维细胞内强烈的绿色或红色荧光。荧光团表现出快速内化、细胞内出色的保留以及胞质环境中的高光学稳定性,并且不会改变细胞活力和重现性。根据分子结构,它们在细胞内经历了不同的命运:从细胞质的明亮而持久的染色到一小组球状蛋白的选择性标记。
