Comprehensive Guide to Stable Lentiviral Cell Line Construction

Experiment Tags: Lentiviral Vectors, Stable Cell Line, Gene Expression, Viral Transduction, Cell Culture, Puromycin Selection, Virus Packaging, Mammalian Cells, Transgene Expression

Experiment Summary: This protocol details the generation of stable cell lines using lentiviral vectors. The method covers plasmid preparation, 293T cell transfection for viral packaging, PEG8000-based virus concentration, target cell infection, antibiotic selection parameters, and single-clone isolation. Includes MOI calculation guidance, troubleshooting for common challenges like low viral titer and poor infection efficiency, and validation strategies for ensuring stable transgene expression.

Ex Vivo Infection of Live Tissue with Oncolytic Viruses

Experiment Tags: Oncolytic viruses, tissue processing, viral infection, fluorescence microscopy, luciferase expression, plaque assay

Experiment Summary: As cancer treatments, oncolytic viruses (OVs) have potential, and determining whether living tissue specimens are infectious ex vivo prior to treatment offers a distinct benefit. This protocol describes the steps involved in preparing tissues for oncolytic virus ex vivo infection and the subsequent measurement of viral activity.

Modeling Hepatitis B Virus Infection in Non-Hepatic 293T-NE-3NRs Cells

Experiment Tags: HBV Infection Model, cell culture, HepG2, Co-culture

Experiment Summary: Current HBV research primarily focuses on hepatocytes, limiting insights into HBV-related pathology in non-hepatic tissues. This study introduces a protocol using non-hepatic 293T and hepatoma cells to investigate HBV infection. Two HBV infection methods were developed based on 293T-NE-3NRs.

Retroviral Capsid Core Stability Assay Protocol

Experiment Tags: Retrovirus, Enveloped Virus, MLV, HIV, Capsid Core Stability Assay, Fate of Capsid Assay, Glycosylated Gag, gPr80, TRIM5α

Experiment Summary: In this protocol, we describe a method using an in vitro detergent-based approach combined with ultracentrifugation for assessing viral capsid core stability. The results show that this method is a significantly simpler and faster way to assess relative capsid core stability.

Antibody-Based CAR T Cells Produced by Lentiviral Transduction Protocol

Experiment Tags: Lentiviral Transduction, CAR T cells

Experiment Summary: In this protocol, an easy and reliable approach for CAR T cell generation is described. T cells are first isolated from peripheral blood and afterwards activated for one day with anti-CD3/CD28 Dynabeads. The gene transfer is performed by lentiviral transduction and gene transfer rate can be verified by flowcytometric analysis.

Varicella Zoster Virus Replication Assays

Experiment Tags: Varicella Zoster Virus (VZV), Replication Assays

Experiment Summary: This protocol describes a basic VZV replication assay using a recombinant VZV-GFP reporter virus. This reporter virus-infected cell line can be used in combination with siRNA gene depletion or cDNA overexpression transfection protocols to determine the effect of individual cellular genes on virus replication.

Protocol for Intrathoracic Inoculation of Zika Virus in Aedes aegypti

Experiment Tags: Aedes aegypti, Mosquito, Zika virus, Arbovirus, Intrathoracic Inoculation, Microinjection

Experiment Summary: This protocol describes herein a protocol for the intrathoracic inoculation of ZIKV in Ae. aegypti. This method bypasses the midgut, which leads to a more rapid and higher proportion of disseminated infections in comparison to oral challenge, and mosquitoes become infected with a consistent dose of virus.

Protocol for Delivering AAV to Express Fluorescent Biosensors in the Juvenile Mouse Hippocampus

Experiment Tags: Adeno-Associated Viruses, Acute Brain Slices, Genetically-Encoded Fluorescent Biosensors, Hippocampus, Intracranial Injection, Dentate Granule cells

Experiment Summary: In this protocol, we describe a protocol for intracranial injections of two viral vectors encoding the metabolic biosensor Peredox and the calcium biosensor RCaMP1h. When combined with 2-photon microscopy and fluorescence lifetime imaging, this protocol allows the simultaneous quantitative assessment of changes in the cytosolic NADH/NAD+ ratio and the intracellular Ca2+ levels in individual dentate granule cells from acute hippocampal slices.
