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).
A Protocol for Comprehensive Assessment of Bulbar Dysfunction in Amyotrophic Lateral Sclerosis (ALS)

Objective assessments of the physiological mechanisms that support speech are needed to monitor disease onset and progression in persons with ALS and to quantify treatment effects in clinical trials. In this video, we present a comprehensive, instrumentation-based protocol for quantifying speech motor performance in clinical populations.
Depletion of Specific Cell Populations by Complement Depletion
BloodCenter of Wisconsin, Blood Research Institute
To effectively study the function of immune cell populations their purification is often required. Complement depletion is a fast and inexpensive technique for the isolation of immune cell populations with high purity.
High-throughput Saccharification Assay for Lignocellulosic Materials
Center for Novel Agricultural Products, University of York
A simple, rapid method for determining the saccharification potential of large numbers of plant biomass samples is described. The automated platform for this analysis involves the preparation of the plant biomass for analysis in 96 well plates and the subsequent performance of pretreatment, hydrolysis and quantification of the sugars released.
Electrolytic Inferior Vena Cava Model (EIM) of Venous Thrombosis
1Conrad Jobst Vascular Research Laboratories, Section of Vascular Surgery, University of Michigan , 2Department of Pharmacology, University of Michigan
The electrolytic induction of endothelial activation to the internal surface of the Inferior Vena Cava results in venous type thrombus formation due to endothelial activation and partial blood stasis, two components of Virchow's triad.
OLIgo Mass Profiling (OLIMP) of Extracellular Polysaccharides
1Energy Biosciences Institute, University of California, Berkeley, 2Department of Plant and Microbial Biology, University of California, Berkeley
A rapid way is described to gain insights into the structure of polysaccharides in an extracellular matrix. The method takes advantage of the specificity of glycosylhydrolases and the sensitivity of mass spectrometry allowing minute amounts of materials to be analyzed. This technique is adaptable to be used directly on tissue itself.
Purification of Specific Cell Population by Fluorescence Activated Cell Sorting (FACS)
Blood Research Institute, BloodCenter of Wisconsin
For many scientific studies requiring a biological and chemical analysis of cell populations the cells must be in a high state of purity. Fluorescence activated cell sorting (FACS) is a superior method in which to obtain pure cell populations.
Isolation of Mouse Peritoneal Cavity Cells
BloodCenter of Wisconsin, Blood Research Institute
The peritoneal cavity in mammals contains different immune cell populations crucial for innate immune responses. An efficient isolation method is required for biochemical and functional analyses of these cells. Here we provide a comprehensive method for the isolation of peritoneal cavity cells in the mouse.
Isolation and Culture of Pulmonary Endothelial Cells from Neonatal Mice
Blood Research Institute, BloodCenter of Wisconsin
Here, we describe a protocol for isolation and culture of murine pulmonary endothelial cells. This method comprises mechanic and enzymatic lung tissue dissociation as well as a 2-step purification process using anti-PECAM-1 and anti-ICAM-2 antibodies conjugated to magnetic beads, which produces a pure endothelial cell population of mostly microvascular origin.
Introducing Shear Stress in the Study of Bacterial Adhesion
Blood vessels as a target for infection, Paris center for cardiovascular research, INSERM U970
During the infection process, a key step is the adhesion of pathogens with host cells. In most instances this adhesion step occurs in the presence of mechanical stress generated by flowing liquid. We describe a technique that introduces shear stress as an important parameter in the study of bacterial adhesion.
