Peptide-PAINT is a cutting-edge technique that has emerged as a powerful tool in super-resolution microscopy, building upon the principles of DNA-PAINT. This method utilizes transient peptide-peptide interactions to achieve remarkable imaging resolution, offering significant advantages for visualizing biological structures at the nanoscale. By employing short peptide sequences that transiently bind, Peptide-PAINT enables scientists to capture detailed images of cellular components with unprecedented clarity, pushing the boundaries of what can be observed in live cells and biological tissues.
At its core, Peptide-PAINT is a single-molecule localization microscopy (SMLM) technique. It operates on the principle of "Point Accumulation for Imaging in Nanoscale Topography" (PAINT), where fluorescence blinking is generated through reversible binding events作者：BK Maity·2023·被引用次数：14—It allowsPeptide-PAINTto be applied to transfected live cells for imaging surface proteins in mammalian cells and neurons under physiological conditions.. Unlike its predecessor, DNA-PAINT, which relies on complementary single-stranded DNA strands, Peptide-PAINT leverages the specific and transient interactions between short peptide sequences.2020年6月11日—LIVE-PAINT: Super-Resolution Microscopy Inside Live Cells Using ReversiblePeptide-Protein Interactions. Curran Oi, Zoe Gidden, Louise ... These peptide-peptide interactions, or sometimes peptide-protein interactions, act as the "docker" and "imager" components, allowing for the controlled association and dissociation of fluorescently labeled molecules. This transient binding creates the necessary blinking events that SMLM techniques require to precisely localize individual molecules and reconstruct a super-resolution image.
The adoption of Peptide-PAINT offers several key advantages for biological imaging.
