A detailed workflow covering 3D pathology, including tissue preparation, imaging with light-sheet fluorescence microscopy, tools for initial data processing in Python (e.g., stitching, intensity leveling and false coloring) and data quality control.
Light-activated assembly of split-protein fragment pairs using the covalent SpyTag/SpyCatcher peptide–protein reaction can be used to modulate biological protein activity in solution, biomaterials and cells.
A customized hyperspectral confocal microscope enables the tracking of living cells and sensing of cellular processes by characterizing bio-integrated microlasers with high spectral resolution.
This protocol provides extensive guidelines and detailed steps to generate novel bio-engineered bacterial strains using CRISPR-associated transposase (CAST) systems, with available plasmids and standard molecular biology techniques.
The Protocol Exchange is an open repository of community-contributed protocols. See the latest, including those for an advanced microfluidic tool for rapid buffer exchange and in situ imaging of phase separation in immobilized giant unilamellar vesicles, carbon and nitrogen nutrient analysis of eucalyptus leaves, and the isolation of viable Plasmodium falciparum merozoites
Our authors are invited to write blog posts that describe how they conceived and developed their protocols, prior to publication at Nature Protocols. These stories are published on a community website for researchers who are interested in techniques and methods.
As part of our ongoing promotion of excellence in protocol and method reporting, we will be contributing to the “Love Methods Week” organized by the Berlin Institute of Health. Online and virtual events will take place 29 January 2024 – 02 February 2024.
This protocol describes an efficient method to reconstitute the onset of gametogenesis by co-culturing resetting hPGCLCs with human hindgut organoids, providing a new framework to clarify the physiological and pathological crosstalk between hPGCs and the hindgut.
The identification and quantitative characterization of tau posttranslational modifications in brain tissue using mass spectrometry provide a comprehensive and untargeted approach to profiling pathological tau in neurodegenerative diseases.
RNA-binding proteins orchestrate many aspects of plant development and environmental responses. This protocol describes an optimized plant individual-nucleotide-resolution cross-linking and immunoprecipitation method for genome-wide identification of RNA-binding protein binding sites on their cognate RNAs at single-nucleotide resolution.
This protocol describes a method for sampling the microbiome of food-processing facilities and analyzing it by using whole-metagenome sequencing. The protocol includes sampling and DNA-extraction and DNA-purification steps optimized for low-biomass samples.

A web-based tool to guide the lead optimization process by improving calculation of substructure modifications of candidate compounds with improved absorption, distribution, metabolism, excretion, and toxicity profiles.
The formation and functional relevance of N6-methyladenosine sites are key unanswered questions in the field of RNA biology. The protocol describes an unbiased sequencing-based method for the characterization of the global distribution and stoichiometry of N6-methyladenosine sites.
Light-activated assembly of split-protein fragment pairs using the covalent SpyTag/SpyCatcher peptide–protein reaction can be used to modulate biological protein activity in solution, biomaterials and cells.
Antigen-specific B cells constitute a small proportion of the total B cell population, making identification for downstream analysis challenging. Here, this is achieved by pairing fluorescent antigen tetramer probes with a sensitive enrichment approach.
