A PCR-based Genotyping Method to Distinguish Between Wild-type and Ornamental Varieties of Imperata cylindrica
1Department of Biological Sciences, The University of Alabama, Huntsville, 2USDA-APHIS-PPQ, Center for Plant Health Science and Technology
We provide a cost-effective and rapid molecular genotyping protocol that employs variety-specific PCR primers that target DNA sequence differences within the chloroplast trnL-F spacer region to differentiate between varieties of Imperata cylindrica (cogongrass) that cannot be distinguished by morphology alone. These varieties include the federally listed noxious weed, cogongrass and closely-related, wide-spread ornamental variety, I. cylindrica var. koenigii (Japanese blood grass).
Cellular Toxicity of Nanogenomedicine in MCF-7 Cell Line: MTT assay
1Research Center for Pharmaceutical Nanotechnology, Faculty of Pharmacy, Tabriz University (Medical Sciences), 2Gifted and Talented Students Office, Educational Development Center, Tabriz University (Medical Sciences), 3School of Advanced Biomedical Sciences, Tabriz University (Medical Sciences)
The MTT assay is an easy and reproducible colorimetric assay for evaluation of cell viability based on reduction of yellow MTT and production of water insoluble purple formazan. Here, the viability of MCF-7 cells upon treatment of nanogenomedicine has been evaluated.
Modified ES / OP9 Co-Culture Protocol Provides Enhanced Characterization of Hematopoietic Progeny

Procedure for fertilizing Xenopus oocytes by the host transfer method.
Determining the Reactivity and Titre of Serum using a Haemagglutination Assay
School of Pharmacy and Medical Sciences, University of South Australia
Haemagglutination is a form of agglutination where antibodies bind to red blood cells. Red blood cells are both readily available and the results are readily observable using the naked eye. This video demonstrates the steps involved in a haemagglutination assay, interpreting the results and determining the titre.
How to Create and Use Binocular Rivalry
1Department of Psychology, New York University, 2Centre for Neural Science, New York University, 3Department of Psychology, Princeton University, 4Neuroscience Institute, Princeton University
Binocular rivalry occurs when the eyes are presented with different images at the same location: one image dominates while the other is suppressed, and dominance alternates periodically. Rivalry is useful for investigating perceptual selection and visual awareness. Here we describe several easy methods for creating and using binocular rivalry stimuli.
Infection of Zebrafish Embryos with Intracellular Bacterial Pathogens
1Department of Molecular Cell Biology, Institute of Biology, Leiden University, 2Department of Medical Microbiology and Infection Control, VU University Medical Center, 3Australian Regenerative Medicine Institute, Monash University
Transparent zebrafish embryos have proved useful model hosts to visualize and functionally study interactions between innate immune cells and intracellular bacterial pathogens, such as Salmonella typhimurium and Mycobacterium marinum. Micro-injection of bacteria and multi-color fluorescence imaging are essential techniques involved in the application of zebrafish embryo infection models.
The Use of Thermal Infra-Red Imaging to Detect Delayed Onset Muscle Soreness
1Loma Linda University, 2Azusa Pacific University
The purpose of this investigation was to assess whether using an infra-red thermal camera is a valid tool for detecting and quantifying the muscle soreness after exercising.
Chromosomics: Detection of Numerical and Structural Alterations in All 24 Human Chromosomes Simultaneously Using a Novel OctoChrome FISH Assay
Genes and Environment Laboratory, University of California, Berkeley
A novel fluorescence in situ hybridization (FISH) method that simultaneously examines both numerical and structural chromosome alterations, particularly the specific chromosomal translocations associated with leukemia and lymphoma, of all 24 human chromosomes on a single device in one hybridization, is described.
Single Cell Fate Mapping in Zebrafish
1Division of Developmental Biology, Cincinnati Children's Hospital Medical Center, 2Division of Hematology/Oncology, Cincinnati Children's Hospital Medical Center
A method is described to photoactivate single cells containing a caged fluorescent protein using two-photon absorption from a Ti:Sapphire femtosecond laser oscillator. To fate map the photoactivated cell, immunohistochemistry is used. This technique can be applied to any cell type.
