Single-strand DNA aptamers as probes for protein localization in cells.

Abstract excerpt

The accurate localization of proteins in fixed cells is important for many studies in cell biology, but good fixation is often antagonistic to good immunolabeling, given the density of well-preserved cells and the size of most labeled antibody probes. We therefore explored the use of single-stranded oligonucleotides (aptamers), which can bind to proteins with very high affinity and specificity but which are only...
