Fluorescence-microscopy Screening and Next-generation Sequencing: Useful Tools for the Identification of Genes Involved in Organelle Integrity
DOE Plant Research Laboratory, Michigan State University
A fundamental quest in cell biology is to define the mechanisms that underlie the identity of the organelles that make eukaryotic cells. Here we propose a method to identify the genes responsible for the morphological and functional integrity of plant organelles using fluorescence microscopy and next-generation sequencing tools.
Rapid Genotyping of Mouse Tissue Using Sigma's Extract-N-Amp Tissue PCR Kit
Department of Developmental and Cell Biology, University of California, Irvine (UCI)
The complete genotyping of a mouse tail sample, including tissue digestion and PCR readout, is done in one and a half hours using Sigma's SYBR Green Extract-N-Amp Tissue PCR kit.
Electrophoretic Separation of Proteins
Proteomic Center, Keck Graduate Institute of Applied Life Sciences
In this video, we demonstrate a method for electrophoretic separation of proteins using poly-acrylimide gel electrophoresis (PAGE).
Immunoblot Analysis
1UVP, LLC, 2Proteomic Center, Keck Graduate Institute of Applied Life Sciences
Immunoblotting (western blotting) is a rapid and sensitive assay for the detection and characterization of proteins that works by exploiting the specificity inherent in antigen-antibody recognition. This video provides protocols for protein separation, blotting proteins onto membranes, immunoprobing, and visualization using chromogenic or chemiluminescent substrates.
Staining Proteins in Gels
1Keck Graduate Institute of Applied Life Sciences, UVP, LLC, 2Proteomic Center, Keck Graduate Institute of Applied Life Sciences
Following separation by electrophoretic methods, proteins in a gel can be detected by several staining methods. Staining of proteins with Coomassie Blue, Silver Staining, SYPRO Orange, SYPRO Ruby are demonstrated in this video.
MISSION esiRNA for RNAi Screening in Mammalian Cells
Max Planck Institute of Molecular Cell Biology and Genetics
Here we use a human esiRNA library in a high-throughput screen for genes involved in cell division. We demonstrate how to set up and conduct an esiRNA screens, as well as how to analyze and validate the results.
Detection of Protein Interactions in Plant using a Gateway Compatible Bimolecular Fluorescence Complementation (BiFC) System
1Department of Biology, University of Western Ontario, 2Southern Crop Protection and Food Research Centre, Agriculture and Agri-Food Canada
We have developed a technique to test protein-protein interactions in plant. A yellow fluorescent protein (YFP) is split into two non-overlapping fragments. Each fragment is cloned in-frame to a gene of interest via Gateway system, enabling expression of fusion proteins. Reconstitution of YFP signal only occurs when the inquest proteins interact.
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
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.
Tissue Determination Using the Animal Cap Transplant (ACT) Assay in Xenopus laevis
Department of Ophthalmology, SUNY Upstate Medical University
Animal caps overexpressing gene product(s) are transplanted to the flank of developing Xenopus laevis embryos in order to establish whether tissue is determined.
A High Throughput in situ Hybridization Method to Characterize mRNA Expression Patterns in the Fetal Mouse Lower Urogenital Tract
Department of Comparative Biosciences, School of Veterinary Medicine, University of Wisconsin-Madison
Here, we describe an efficient high throughput in situ hybridization (ISH) method for visualizing patterns of mRNA expression in developing fetal mouse prostate tissue sections. The method can be easily adapted to visualize mRNA expression patterns in other mouse tissues or in tissues from other species.
