Two methods for fluorescence-based actinometry using organic dyes and photoconvertible fluorescent proteins enable rapid and precise measurement of light intensity at the sample in fluorescence microscopes.
Cardinal v.3 is an open-source software for reproducible analysis of mass spectrometry imaging experiments, and includes data processing features such as mass recalibration, statistical analyses such as single-ion segmentation and rough annotation-based classification, and analyses of large-scale multitissue experiments.
SegCLR automatically annotates segmented electron microscopy datasets of the brain with information such as cellular subcompartments and cell types, using a self-supervised contrastive learning approach.
This manuscript describes a refinement protocol that extends the e2gmm method to optimize both the orientation and conformation estimation of particles to improve the alignment for flexible domains of proteins.
DeepSeMi is a self-supervised denoising framework that can enhance SNR over 12 dB across diverse samples and imaging modalities. DeepSeMi enables extended longitudinal imaging of subcellular dynamics with high spatiotemporal resolution.
Enhanced super-resolution radial fluctuations (eSRRF) offers improved image fidelity and resolution compared to the popular SRRF method and further enables volumetric live-cell super-resolution imaging at high speeds.
A phenylalanine-containing peptide probe can be used for discriminating all 20 amino acids via current blockage during translocation through an α-hemolysin (αHL) nanopore. The paper provides proof-of-concept peptide sequencing demonstrations.
Adaptable, turn-on maturation (ATOM) biosensors use monobody or nanobody targeting to control fluorescent protein maturation for fluorescence in the presence of target biomolecules, enabling bright and specific cellular biosensing.
Genetically encoded multimeric particles (GEMs) are 25-nm tags with recognizable structural signatures, which can be used to label specific proteins in mammalian cells to facilitate their subcellular localization in cryo-ET.
A pulsed illumination scheme renders stimulated Brillouin microscopy less phototoxic and allows imaging of the mechanical properties of sensitive samples such as single cells, Caenorhabditis elegans embryos, zebrafish larvae and organoids.
nextPYP is a turn-key framework for single-particle cryo-electron tomography that streamlines complex data analysis pipelines, from pre-processing of tilt series to high-resolution refinement, for efficient analysis and visualization of large datasets.
An engineered RNA A-to-I deaminase (rABE) offers low sequence bias, high activity and low background for REMORA (RNA-encoded molecular recording in adenosines) and enables improved molecular recording of RNA–protein interactions.
This work introduces microbial-enrichment methodology (MEM) that enables removal of host DNA in human intestinal biopsies and characterization of low-abundance microbial taxa down to 1%.
