Protocols for In vitro Transcription (IVT) and tRNA Binding Assay

Experiment Tags: T-box (T-box), EMSA (EMSA), RNA-RNA Interaction, TRNA (tRNA), In Vitro Transcription

Experiment Summary: This protocol describes the coupling of (i) “live” in vitro RNA transcription with (ii) binding by a radiolabeled, pre-formed tRNA followed by native gel electrophoresis and phosphorimager scan to visualize the complex.

Protocol on Respiratory Syncytial Virus Infection in Mice and Detection of Viral Genomes in the Lung Using RT-qPCR

Experiment Tags: Respiratory Syncytial Virus, Respiratory Infection, Virus Detection

Experiment Summary: In this protocol, we discuss in detail how to infect BALB/c mice with RSV and how to detect the RSV genome in mouse lungs using reverse transcription quantitative PCR (RT-qPCR).

Protocol for Transient yet Robust Expression of Proteins in the Mouse Liver via Intravenous Injection of Lipid Nanoparticle-encapsulated Nucleoside-modified mRNA

Experiment Tags: Nucleoside-Modified mRNA, Lipid Nanoparticle, Liver Regeneration, Protein Expression, Retro-orbital Injection

Experiment Summary: In this protocol, we describe in detail the necessary steps to deliver mRNA-LNP to the murine liver and, following intravenous injection of eGFP mRNA-LNP, verify transfection efficiency using flow cytometry and liver cell specificity using immunofluorescence analyses.

Protocol for Selecting Vaccinia Virus Recombinants Using CRISPR/Cas9

Experiment Tags: Recombinant Virus, Vaccinia Virus, VACV (VACV), CRISPR/Cas9 Selection, Virotherapy, Vaccine Development

Experiment Summary: In this protocol, we describe protocols for the generation and enrichment of recombinant vaccinia viruses using targeted Cas9 as a selection tool. This novel use of Cas9 is a simple addition to current homologous recombination-based methods that are widespread in the field, facilitating implementation in laboratories already working with poxviruses.

Protocol for Detection of Cytoplasmic and Nuclear Circular RNA via RT-qPCR

Experiment Tags: Subcellular Fractionation, RT-qPCR, Circular RNA, circRNA, Cytoplasmic circRNA, Nuclear circRNA, Low-Abundance circRNA

Experiment Summary: In this protocol, we present a protocol for the subcellular fractionation of cells to detect circRNA via RT-qPCR with divergent primers. Moreover, detailed steps for the generation of specific circRNAs-enriched cDNA included in this protocol will enhance the amplification and detection of low-abundance circRNAs.

Preparation of dsRNA by In Vitro Transcription Protocol

Experiment Tags: dsRNA Synthesis, In Vitro Preparation

Experiment Summary: In this protocol, we describe a simple and widely used in vitro transcription reaction for the preparation of double-stranded RNA using PCR templates. The dsRNA prepared by this method can be used to induce RNA interference in certain cells or tissues.
