This protocol describes toxin activation–inhibition conjugation (TAC–TIC), a reverse genetics screening approach that can be used to identify triggers or blockers of bacterial toxin–antitoxin or phage immunity systems.
The buildup and operation of a custom single-molecule localization microscope with state-of-the-art performance and advanced features bridges the gap between entry-level open-source projects and costly commercial systems.
This protocol details the generation of cortical organoids with complex neural oscillations through a ‘semi-guided’ protocol, and their functional characterization using microelectrode array measurements, calcium imaging and adeno-associated virus transduction.
Ancient proteins carry genetic information from fossils that are too old or degraded for ancient DNA recovery. This protocol describes the extraction and tandem mass spectrometry sequencing of million-year-old dental enamel proteins for phylogenetic inference.
This protocol details methods for using methanol in methylation reactions, including the synthesis of suitable transition metal-containing catalysts, and in the synthesis of heterocycles. The methods described produce only H2 and H2O as by-products.
Isotope ratio mass spectrometry as described in this protocol can be used to determine natural variation in the abundance of stable isotopes in individual compounds to provide information relevant to metabolism, ecology or climate change.
Surface photovoltage microscopy as described in this protocol allows high spatial and energy resolution mapping of surface-charge distributions on photocatalyst particles, enabling rational design of improved materials.
NanoLuciferase- and HaloTag-based screening technologies are versatile tools suitable for the live-cell analysis of the entire small-molecule-induced degradation cascade to uncover the mode of action of proximity-inducing compounds such as PROTACs.
This protocol describes the preparation of long-lasting aggregation-induced emission-based, near-infrared afterglow luminescence nanoprobes. Their enhanced afterglow intensity results in improved imaging sensitivity and depth in vivo.
A protocol for the generation of induced blastoids, an in vitro integrated model of the human blastocyst derived via somatic reprogramming. This model overcomes restrictions associated with the use of human blastocysts in embryology research.
Activated neutrophils labeled with NIR-II lanthanide downshifting nanoparticles can be sequentially imaged through the intact skull of a mouse model of ischemic stroke during adhesion, crawling and extravasation processes
This protocol describes the establishment of a reversible replication barrier using plasmid templates containing a lacO array bound by LacR repressor. The method allows fine control of replication fork movement and replication fork encounter with DNA lesions.
It can be challenging to obtain meaningful and accurate structural information for air-sensitive proteins. This protocol describes the application of customized vacuum manifold and anaerobic chamber setups for the purification and cryo-electron microscopy analysis of air-sensitive nitrogenase enzymes.
Attempts to reproduce the computational steps described in published omics research often fail. This review provides guidelines for the packaging and containerization of software so that readers can use the exact programs used in published work.
Isotopically labeled amino acids are useful in pharmacology and for medical imaging. In this protocol, C1-labeled α-amino acids are prepared via late-stage carboxylate exchange of unprotected α-amino acids with [*C]CO2 where *C is 13C, 11C or 14C.
We present a protocol for achieving efficient generation of hPSC-CM aggregates in suspension culture, emphasizing process simplicity, robustness and GMP compliance. The strategy promotes clinical translation and other applications that require large numbers of CMs.
This protocol can be used to generate three-dimensional vascularized bone marrow organoids from human induced pluripotent stem cells. The organoids contain key stromal and hematopoietic cell types and can be engrafted with normal and malignant cells from adult donors to model niche interactions.
Cell engineering using polymeric material is an area that remains largely unexplored. This protocol describes two light-driven approaches for synthesizing bioactive polymers within intricate intracellular settings.
This protocol is for using PanSyn, the first software package for the identification of micro- and macrosynteny and their functional integration for comprehensive characterization of genome architecture and regulatory evolution.
Genetic interactions have been found to influence phenotypes in a variety of systems, yet their specific contribution to complex diseases remains unclear. This protocol describes Bridging Gene sets with Epistasis (BridGE), a computational approach for discovering interactions between biological pathways from genome-wide association studies data.
