High-throughput, Automated Extraction of DNA and RNA from Clinical Samples using TruTip Technology on Common Liquid Handling Robots

1Application Development, Akonni Biosystems, Inc., 2Manufacturing, Akonni Biosystems, Inc., 3Engineering, Akonni Biosystems, Inc., 4Research & Development, Akonni Biosystems, Inc.


JoVE 50356

TruTip is a simple nucleic acid extraction technology whereby a porous, monolithic binding matrix is inserted into a pipette tip. Consequently, the sample preparation format is compatible with most liquid handling instruments, and can be used for many medium to high-throughput clinical applications and sample types.

Extraction of High Molecular Weight DNA from Microbial Mats

1Department of Environmental Health Sciences, Arnold School of Public Health, University of South Carolina


JoVE 2887

We provide an improved protocol for extracting high molecular weight DNA from hypersaline microbial mats. Microbial cells are separated from the mat matrix prior to DNA extraction and purification. This enhances the concentrations, quality, and size of the DNA. The protocol may be used for other refractory samples.

DNA Extraction from Paraffin Embedded Material for Genetic and Epigenetic Analyses

1Department of Integrative Oncology, BC Cancer Research Centre, 2Interdisciplinary Oncology Program, University of British Columbia - UBC, 3Photography/Video Production, Multi-Media Services, BC Cancer Agency, 4Department of Pathology and Laboratory Medicine, University of British Columbia - UBC


JoVE 2763

This video demonstrates the protocol for DNA extraction from formalin-fixed paraffin-embedded material. This is a multi-day procedure in which tissue sections are deparaffinized with xylene, rehydrated with ethanol and treated with proteinase K to purify and isolate DNA for subsequent gene-specific or genome-wide analysis.

A Simple Chelex Protocol for DNA Extraction from Anopheles spp.

1Malaria Institute at Macha, 2Department of Molecular Microbiology & Immunology, Johns Hopkins Bloomberg School of Public Health


JoVE 3281

A rapid and affordable way to extract quality malaria parasite and vector DNA from mosquito specimens is described. Capitalizing on chelating properties of Chelex resin, the simple method enables genotyping of malaria parasites in mosquito mid-gut and salivary gland phases, as well as molecular identification of the Anopheles sibling species by PCR.

DNA Extraction from 0.22 μM Sterivex Filters and Cesium Chloride Density Gradient Centrifugation

1Department of Microbiology and Immunology, University of British Columbia - UBC


JoVE 1352

We describe a method for extraction of high molecular weight genomic DNA from planktonic biomass concentrated on 0.22 μm Sterivex filters, followed by cesium chloride density gradient centrifugation for purification.

Polymerase Chain Reaction: Basic Protocol Plus Troubleshooting and Optimization Strategies

1Microbiology, Immunology, and Molecular Genetics, University of California, Los Angeles


JoVE 3998

PCR has emerged as a common technique in many molecular biology laboratories. Provided here is a quick guide to several conventional PCR protocols. Because each reaction is a unique experiment, optimal conditions required to generate a product vary. Understanding the variables in a reaction will greatly enhance troubleshooting efficiency, thereby increasing the chance to obtain the desired result.

A Practical and Novel Method to Extract Genomic DNA from Blood Collection Kits for Plasma Protein Preservation

1Division of Gastroenterology, Hepatology and Nutrition, Department of Pediatrics, Emory University School of Medicine and Children's Health Care of Atlanta, 2Division of Rheumatology, Department of Pediatrics, Emory University School of Medicine and Children's Health Care of Atlanta


JoVE 4241

We are describing a new method of isolating genomic DNA from whole blood collected for plasma/serology. After plasma collection, the compacted blood is usually discarded. Our novel method represents a significant improvement over existing methods and makes DNA and plasma available from a single collection, without requesting additional blood.

Chromatin Interaction Analysis with Paired-End Tag Sequencing (ChIA-PET) for Mapping Chromatin Interactions and Understanding Transcription Regulation

1Genome Institute of Singapore, Agency for Science, Technology and Research, Singapore, 2A*STAR-Duke-NUS Neuroscience Research Partnership, Singapore, 3Department of Biochemistry, National University of Singapore, Singapore


JoVE 3770

Chromatin Interaction Analysis by Paired-End Tag Sequencing (ChIA-PET) is a method for de novo detection of chromatin interactions, for better understanding of transcriptional control.

An Affordable HIV-1 Drug Resistance Monitoring Method for Resource Limited Settings

1Africa Centre for Health and Population Studies, College of Health Sciences, University of KwaZulu-Natal, Durban, South Africa, 2Unit D11, Jembi Health Systems, 3Academic Medical Center, Department of Global Health, Amsterdam Institute for Global Health and Development (AIGHD), University of Amsterdam, 4Division of Infectious Diseases and Geographic Medicine, Centre for AIDS Research, Stanford Medical School


JoVE 51242

Drug resistance testing for HIV-1 infected individuals failing antiretroviral therapy (ART) can guide future therapies and improve treatment outcomes. Optimizing individual and population health outcomes in high HIV prevalence but resource-limited settings will ultimately require affordable and accessible drug resistance genotyping and interpretation methods.
