High-Throughput Measurement and Classification of Organic P in Environmental Samples
School of Engineering, University of Vermont
This protocol describes a high-throughput method of enzymatic hydrolysis that utilizes a microplate reader to measure and classify soil phosphorus as P monoesters, P diesters and inorganic P. Up to 96 samples can be measured at one time in a standard laboratory.
Peptides from Phage Display Library Modulate Gene Expression in Mesenchymal Cells and Potentiate Osteogenesis in Unicortical Bone Defects
1Orthopaedics Research, University of Virginia, 2Biological Sciences, University of Delaware, 3Orthopaedic Surgery, University of Virginia
A phage display library was used to identify peptide sequences that target bone. The objective was to investigate the effect of these peptides on mesenchymal cell differentiation and to determine their effect on bone regeneration.
PAR-CliP - A Method to Identify Transcriptome-wide the Binding Sites of RNA Binding Proteins

RNA transcripts are subject to extensive posttranscriptional regulation that is mediated by a multitude of trans-acting RNA-binding proteins (RBPs). Here we present a generalizable method to identify precisely and on a transcriptome-wide scale the RNA binding sites of RBPs.
Quantification of γH2AX Foci in Response to Ionising Radiation
1Epigenomic Medicine, Baker IDI Heart and Diabetes Institute, The Alfred Medical Research and Education Precinct, 2Department of Pathology, The University of Melbourne, 3Epigenetics in Human Health and Disease, Baker IDI Heart and Diabetes Institute, The Alfred Medical Research and Education Precinct
Quantification of DNA double-strand streaks using γH2AX formation as a molecular marker has become an invaluable tool in radiation biology. Here we demonstrate the use of an immunofluorescence assay for quantification of γH2AX foci after exposure of cells to radiation.
Isolation and Analysis of Hematopoietic Stem Cells from the Placenta
Jonsson Comprehensive Cancer Center, University of California, Los Angeles
We have identified the placenta as a major hematopoietic organ during development. We found that hematopoietic stem cells (HSCs) are both generated and expanded in the placenta in unique microenvironmental niches. Here, we describe experimental techniques required for isolation and visualization of HSCs in the mouse placenta.
Generation of Induced Pluripotent Stem Cells by Reprogramming Human Fibroblasts with the Stemgent Human TF Lentivirus Set
Research and Development, Stemgent
We demonstrate the protocol for the generation of induced pluripotent stem cells from human somatic cells using lentivirus-mediated delivery of the human factors Oct4, Sox2, Nanog, and Lin28. Pluripotency was confirmed by morphology and the presence of embryonic stem (ES) cell-specific markers.
Genome-wide Analysis of Aminoacylation (Charging) Levels of tRNA Using Microarrays
Department of Biochemistry and Molecular Biology, University of Chicago
We describe a method for microarray analysis to determine relative aminoacylation levels of all tRNAs from S. cerivisiae.
Western Blotting: Sample Preparation to Detection
Research and Development, EMD Chemicals Inc.
Western blotting is an analytical technique used to detect specific proteins in a given sample of tissue homogenate or extract.
A Cell Free Assay System Estimating the Neutralizing Capacity of GM-CSF Antibody using Recombinant Soluble GM-CSF Receptor
1Bioscience Medical Research Center, Niigata University Medical and Dental Hospital, 2First department of Internal Medicine, School of Medicine, Kyorin University, 3Neosilk Laboratory, Immuno Biological Laboratories Co., Ltd.
We designed a cell-free receptor binding assay in order to estimate the binding of granulocyte-macrophage colony-stimulating factor (GM-CSF) to the receptors. It enables us to evaluate competitive inhibition of biotinylated GM-CSF binding to soluble GM-CSF receptor alpha by GM-CSF autoantibody with excellent reproducibility.
Live Dissection of Drosophila Embryos: Streamlined Methods for Screening Mutant Collections by Antibody Staining
Division of Biology, California Institute of Technology
We describe a streamlined protocol for generating "fillet" preparations of Drosophila embryos of specific genotypes. This protocol allows efficient execution of a variety of genetic screens. It also allows excellent visualization of structures in the late embryo.
