SDS-PAGE/Immunoblot Detection of Aβ Multimers in Human Cortical Tissue Homogenates using Antigen-Epitope Retrieval

1Yerkes National Primate Research Center, Emory University, 2Department of Neurology, Institute of Clinical Medicine, Tsukuba University, 3Department of Pathology, New York University School of Medicine, 4Department of Neurology, Emory University


JoVE 1916

We describe a technique for the preparation of clarified human cortical homogenates, protein separation by SDS-PAGE, antigen retrieval and immunoblotting with an antibody to the Aβ peptide. Using this protocol, we consistently detect monomeric and multimeric Aβ in cortical tissue from humans with Alzheimer's pathology.

Denaturing Urea Polyacrylamide Gel Electrophoresis (Urea PAGE)

1School of Biological Sciences, Nanyang Technological University, Singapore - NTU, 2Singapore-MIT Alliance for Reserach and Technology (SMART)


JoVE 1485

Denaturing urea polyacrylamide gel electrophoresis is used to separate single-stranded DNA or RNA up to a limit of 500 nucleotides. Urea in combination with heat denatures samples and unstructured single strands migrate within the gel matrix according to their molecular weight.

Blue Native Polyacrylamide Gel Electrophoresis (BN-PAGE) for Analysis of Multiprotein Complexes from Cellular Lysates

1Spemann Graduate School of Biology and Medicine (SGBM), University of Freiburg, 2Centre for Biological Signalling Studies (bioss) and Biology III, Faculty of Biology, University of Freiburg, 3Department of Molecular Immunology, Max-Planck-Institute of Immunology and Epigenetics


JoVE 2164

In this video, we describe the characterization of multiprotein complexes (MPCs) by blue native polyacrylamide gel electrophoresis (BN-PAGE). In a first dimension, dialyzed cellular lysates are separated by BN-PAGE to identify individual MPCs. In a second dimension SDS-PAGE, MPCs of interest are further subdivided to analyze their constituents by immunoblotting.

Protein WISDOM: A Workbench for In silico De novo Design of BioMolecules

1Department of Chemical and Biological Engineering, Princeton University


JoVE 50476

We developed computational de novo protein design methods capable of tackling several important areas of protein design. To disseminate these methods we present Protein WISDOM, an online tool for protein design (http://www.proteinwisdom.org). Starting from a structural template, design of monomeric proteins for increased stability and complexes for increased binding affinity can be performed.

Using Continuous Data Tracking Technology to Study Exercise Adherence in Pulmonary Rehabilitation

1Individualized Program, Concordia University, 2Department of Exercise Science, Concordia University, 3Centre de Recherche, Axe Maladies Chroniques, Hôpital du Sacré-Coeur de Montréal


JoVE 50643

Pulmonary rehabilitation is widely recognized in the management of respiratory diseases. A key component to successful pulmonary rehabilitation is adherence to the recommended exercise training. The purpose of the present protocol is to describe how continuous data tracking technology can be used to precisely measure adherence to a prescribed aerobic training intensity.

Using an Automated 3D-tracking System to Record Individual and Shoals of Adult Zebrafish

1R&D, xyZfish


JoVE 50681

The use of a 3D automatic video system that can track individual and groups of zebrafish is described. As application example we explore the effects of the NMDA-receptor antagonist MK-801 on shoals of zebrafish.

Detection of Architectural Distortion in Prior Mammograms via Analysis of Oriented Patterns

1Department of Electrical and Computer Engineering, Schulich School of Engineering, University of Calgary, 2Department of Radiology, University of Calgary


JoVE 50341

We demonstrate methods for the detection of architectural distortion in prior mammograms. Oriented structures are analyzed using Gabor filters and phase portraits to detect sites of radiating tissue patterns. Each site is characterized and classified using measures to represent spiculating patterns. The methods should assist in the detection of breast cancer.

Automated, Quantitative Cognitive/Behavioral Screening of Mice: For Genetics, Pharmacology, Animal Cognition and Undergraduate Instruction

1Department of Psychology, Rutgers University, 2Department of Psychology, Koç University, 3Center for Neural Science, New York University, 4Department of Mathematics & Computer Science, Fairfield University


JoVE 51047

Fully automated system for measuring physiologically meaningful properties of the mechanisms mediating spatial localization, temporal localization, duration, rate and probability estimation, risk assessment, impulsivity, and the accuracy and precision of memory, in order to assess the effects of genetic and pharmacological manipulations on foundational mechanisms of cognition in mice.

Measuring Material Microstructure Under Flow Using 1-2 Plane Flow-Small Angle Neutron Scattering

1Center for Neutron Science, Department of Chemical and Biomolecular Engineering, University of Delaware, 2NIST Center for Neutron Research, National Institute of Standards and Technology, 3Institut Laue-Langevin


JoVE 51068

A shear cell is developed for small-angle neutron scattering measurements in the velocity-velocity gradient plane of shear and is used to characterize complex fluids. Spatially resolved measurements in the velocity gradient direction are possible for studying shear-banding materials. Applications include investigations of colloidal dispersions, polymer solutions, and self-assembled structures.

Designing a Bio-responsive Robot from DNA Origami

1Faculty of Life Sciences and the Institute for Nanotechnology & Advanced Materials, Bar-Ilan University


JoVE 50268

DNA origami is a powerful method for fabricating precise nanoscale objects by programming the self-assembly of DNA molecules. Here, we describe how DNA origami can be utilized to design a robotic robot capable of sensing biological cues and responding by shape shifting, subsequently relayed to a desired effect.
