A Quantitative Evaluation of Cell Migration by the Phagokinetic Track Motility Assay
1Department of Microbiology and Immunology, Louisiana State University Health Sciences Center, 2Center for Molecular and Tumor Virology, Louisiana State University Health Sciences Center, 3Department of Microbiology and Immunology, SUNY Upstate Medical University, 4Feist-Weiller Cancer Center, Louisiana State University Health Sciences Center
The phagokinetic motility track assay is a method used to assess the movement of cells. Specifically, the assay measures chemokinesis (random cell motility) over time in a quantitative manner. The assay takes advantage of the ability of cells to create a measurable track of their movement on colloidal gold-coated coverslips.

Comprehensive Profiling of Dopamine Regulation in Substantia Nigra and Ventral Tegmental Area
Dopamine is distinctly regulated in the midbrain nuclei, which contain the cell bodies and dendrites of the dopamine neurons. Here we describe a dissection and sample-handling approach to maximize results, and thus conclusions and insights, on dopamine regulation in the midbrain nuclei of the substantia nigra (SN) and ventral tegmental area (VTA) in rodents.

Isolation and Culture of Rat Embryonic Neural Cells: A Quick Protocol
1LSU Health Sciences Center - New Orleans, 2Medical School and Stanley S. Scott Cancer Center
We describe a rapid methodology to isolate and culture hippocampal and cortical neurons from rodent embryos. This protocol allows us to perform experiments in which nearly pure neuronal cultures are required.

Quantitative Analysis of Random Migration of Cells Using Time-lapse Video Microscopy
1Department of Biochemistry and Molecular Biology, LSU School of Medicine, 2Department of Oral Biology, LSU School of Dentistry, 3Stanley S. Scott Cancer Center, LSU School of Medicine
This method allows monitoring of cells in real time and quantitative measurements of different cell migration parameters such as speed, displacement, and velocity. Unlike the traditional methods, this real time approach is not based on endpoint quantitative migration measurements; instead it allows monitoring and calculating different parameters continuously.

Methods to Assay Drosophila Behavior
1Department of Pharmacology and Experimental Therapeutics, Louisiana State University Health Sciences Center, 2Department of Genetics, Louisiana State University Health Sciences Center
Drosophila melanogaster is a genetically and behaviorally tractable model system that has been used to understand the molecular and cellular basis of many important biological processes for over a century 1. Drosophila has been well exploited to gain insights into the genetic basis of fly behavior.

Measurement of Cytosolic Ca2+ in Isolated Contractile Lymphatics
Department of Physiology, School of Medicine, Louisiana State University Health Sciences Center
We introduce an approach to evaluate the cytosolic Ca2+ concentration in isolated lymphatics to study Ca2+-dependent and Ca2+-sensitizing mechanisms of lymphatic smooth muscle contraction.

Protocols for Vaginal Inoculation and Sample Collection in the Experimental Mouse Model of Candida vaginitis
Louisiana State University Health Sciences Center
Key techniques to be used in the evaluation of Candida vaginitis in an experimental animal model are described. The methods will allow rapid collection of vaginal specimens and lymphocytes from draining lumbar lymph nodes. These techniques could give rise to mouse models of other diseases in the female lower genital tract.

Isolation of Mouse Lung Dendritic Cells
Pathobiological Sciences, Louisiana State University
A highly purified preparation of mouse lung dendritic cells is described. Specific emphasis is given to the isolation of conventional dendritic cell subset.

Study of the Actin Cytoskeleton in Live Endothelial Cells Expressing GFP-Actin
Department of Physiology, Louisiana State University Health Sciences Center
Microscopic imaging of live endothelial cells expressing GFP-actin allows characterization of dynamic changes in cytoskeletal structures. Unlike techniques that use fixed specimens, this method provides a detailed assessment of temporal changes in the actin cytoskeleton in the same cells before, during, and after various physical, pharmacological, or inflammatory stimuli.

Bioassays for Monitoring Insecticide Resistance
1Division of Plant Sciences, University of Missouri, Delta Research Center, 2Department of Entomology, Louisiana State University Agricultural Center
This manuscript demonstrates and discusses techniques used to survey pesticide susceptibility and detect resistance to contact and systemic pesticides in arthropod pests.

Testing Protozoacidal Activity of Ligand-lytic Peptides Against Termite Gut Protozoa in vitro (Protozoa Culture) and in vivo (Microinjection into Termite Hindgut)
Department of Entomology, Louisiana State University Agricultural Center
We present procedures for demonstrating that ligands bind to the surface membrane of the cellulose-digesting protozoa in the gut of Formosan subterranean termites using fluorescent microscopy and that ligands coupled with lytic peptides kill these protozoa in vitro (anaerobic protozoa culture) and in vivo (injection into the termite hindgut).
