Uniform protein labeling in intact tissues is a challenge. An approach that allows antibodies to seep within organs could label proteins in millions of cells. Sahana is a science journalist and an ...
To site-specifically label proteins in living cells, researchers mutate an enzyme to recognize a small fluorophore and catalyze its attachment to a small peptide tag. Fluorescent protein fusions ...
A strategy for labeling cell-surface proteins in living cells with small-molecule fluorophores allowed scientists to study receptor trafficking by single-cell FRET imaging in real time. When ...
