Preparation of SNAP f -Beads for Colocalization Single-Molecule Spectroscopy (CoSMoS) of RNA-Protein Complexes.
Methods in molecular biology (Clifton, N.J.)(2020)
摘要
The SNAP-tag is a chemical tag that allows rapid and highly specific covalent labeling of proteins even in the full complexity of the cellular environment. The SNAP-tag has been instrumental to study native RNA-protein complexes at single-molecule resolution in their cellular environment as efficient labeling of the RNAs and proteins of interest is essential for this colocalization single-molecule spectroscopy (CoSMoS) technique. However, removal of excessive benzylguanine dye after the labeling reaction has remained challenging. Here, we describe a strategy to remove excessive benzylguanine dye using SNAP-tag coated beads as sponges.
