Protease- and Acid-catalyzed Labeling Workflows Employing 18O-enriched Water

1Boston Biomedical Research Institute


JoVE 3891

Stable isotope labeling workflows employing 18O-enriched water (LeO-workflows) are versatile tools for quantitative and qualitative proteomics studies. In protease-assisted (PALeO) workflows, 18O-atoms are introduced by proteolytic cleavage and carboxyl oxygen exchange reactions mediated by proteases. In the acid-catalyzed (ALeO) workflow, 18O-atoms are introduced by carboxyl oxygen exchange at low pH.

F1FO ATPase Vesicle Preparation and Technique for Performing Patch Clamp Recordings of Submitochondrial Vesicle Membranes

1Department of Internal Medicine, Yale University


JoVE 4394

A method to isolate submitochondrial vesicles enriched in F1FO ATP synthase complexes from rat brain is described. These vesicles allow the study of the activity of F1FO ATPase complex and its modulation using the technique of patch clamp recording.

Glycan Profiling of Plant Cell Wall Polymers using Microarrays

1Australian Centre of Excellence in Plant Cell Walls, School of Botany, University of Melbourne, 2Plant Cell Biology Research Centre, School of Botany, University of Melbourne, 3CSIRO Plant Industry, Black Mountain Laboratories, 4Department of Plant Biology and Biotechnology, University of Copenhagen


JoVE 4238

A technique called Comprehensive Microarray Polymer Profiling (CoMPP) for the characterisation of plant cell wall glycans is described. This method combines the specificity of monoclonal antibodies directed to defined glycan-epitopes with a miniature microarray analytical platform allowing screening of glycan occurrence in a broad range of biological contexts.

Chemically-blocked Antibody Microarray for Multiplexed High-throughput Profiling of Specific Protein Glycosylation in Complex Samples

1Institute for Hepatitis and Virus Research, 2Department of Microbiology and Immunology, Thomas Jefferson University, 3Drexel University College of Medicine, 4Van Andel Research Institute, 5Institute for Hepatitis and Virus Research, Serome Biosciences Inc.


JoVE 3791

In this study, we describe an improved protocol for a multiplexed high-throughput antibody microarray with lectin detection method that can be used in glycosylation profiling of specific proteins. This protocol features new reliable reagents and significantly reduces the time, cost, and lab equipment requirements as compared to the previous procedure.

A Lectin HPLC Method to Enrich Selectively-glycosylated Peptides from Complex Biological Samples

1Obstetrics, Gynecology and Reproductive Sciences, University of California, San Francisco - UCSF, 2Buck Institute for Age Research, 3Department of Chemistry, Purdue University


JoVE 1398

Lectin-conjugated POROS beads were employed for HPLC. Glycopeptide standards served as positive and negative controls. MARS-14 depleted, trypsin-digested human plasma was chromatographed and flow-through (FT) and bound fractions collected for ESI-LC-MS/MS analyses. Glycopeptides were enriched in the bound fraction as compared to FT.

An Allelotyping PCR for Identifying Salmonella enterica serovars Enteritidis, Hadar, Heidelberg, and Typhimurium

1Department of Population Health, University of Georgia


JoVE 3130

We describe a multiplex PCR for the rapid detection of Salmonella enterica serovars Enteritidis, Hadar, Heidelberg, and Typhimurium. Specific Salmonella serovars can be identified by targeting a multiplex PCR to genes and sequences unique to the O-antigen biosynthesis cluster and flagellin of a given serovar. Serovar is assigned then to a Salmonella isolate based on the appearance of specific, size amplicons (PCR product) corresponding to the target allele.

Non-radioactive in situ Hybridization Protocol Applicable for Norway Spruce and a Range of Plant Species

1Department of Evolutionary Functional Genomics, Evolutionary Biology Center, Uppsala University, 2Department of Plant Biology and Forest Genetics, Uppsala BioCenter, Swedish University of Agricultural Sciences


JoVE 1205

We describe a modified DIG in situ hybridization protocol, which is fast and applicable on a wide range of plant species including Norway spruce. With just a few adjustments, including altered RNase treatment and proteinase K concentration, the protocol may be used in studies of different tissues and species.

Aseptic Laboratory Techniques: Plating Methods

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


JoVE 3064

When working with media and reagents used to culture microorganisms, aseptic technique must be practiced to ensure contamination is minimized. A variety of plating methods are routinely used to isolate, propagate, or enumerate bacteria and phage, all of which incorporate procedures that maintain the sterility of experimental materials.

Analyzing Protein Dynamics Using Hydrogen Exchange Mass Spectrometry

1Zentrum für Molekulare Biologie der Universität Heidelberg (ZMBH), University of Heidelberg


JoVE 50839

Protein conformation and dynamics are key to understanding the relationship between protein structure and function. Hydrogen exchange coupled with high-resolution mass spectrometry is a versatile method to study the conformational dynamics of proteins as well as characterizing protein-ligand and protein-protein interactions, including contact interfaces and allosteric effects.
