Lumi-ImagerTM F1


Book Description

The instrument Lumi-Imager was developed for the detection and accurate quantification of chemiluminescent signals on blots and in microtiter plates. It contains a cooled CCD camera, a specially developed lens system and software. In addition to luminescence, Lumi-Imager F1 can also detect and quantify UV-excited fluorescent signals in gels. Here we describe the components and features of this instrument as well as some of its applications.

Statistical Parametric Mapping: The Analysis of Functional Brain Images


Book Description

In an age where the amount of data collected from brain imaging is increasing constantly, it is of critical importance to analyse those data within an accepted framework to ensure proper integration and comparison of the information collected. This book describes the ideas and procedures that underlie the analysis of signals produced by the brain. The aim is to understand how the brain works, in terms of its functional architecture and dynamics. This book provides the background and methodology for the analysis of all types of brain imaging data, from functional magnetic resonance imaging to magnetoencephalography. Critically, Statistical Parametric Mapping provides a widely accepted conceptual framework which allows treatment of all these different modalities. This rests on an understanding of the brain's functional anatomy and the way that measured signals are caused experimentally. The book takes the reader from the basic concepts underlying the analysis of neuroimaging data to cutting edge approaches that would be difficult to find in any other source. Critically, the material is presented in an incremental way so that the reader can understand the precedents for each new development. This book will be particularly useful to neuroscientists engaged in any form of brain mapping; who have to contend with the real-world problems of data analysis and understanding the techniques they are using. It is primarily a scientific treatment and a didactic introduction to the analysis of brain imaging data. It can be used as both a textbook for students and scientists starting to use the techniques, as well as a reference for practicing neuroscientists. The book also serves as a companion to the software packages that have been developed for brain imaging data analysis. - An essential reference and companion for users of the SPM software - Provides a complete description of the concepts and procedures entailed by the analysis of brain images - Offers full didactic treatment of the basic mathematics behind the analysis of brain imaging data - Stands as a compendium of all the advances in neuroimaging data analysis over the past decade - Adopts an easy to understand and incremental approach that takes the reader from basic statistics to state of the art approaches such as Variational Bayes - Structured treatment of data analysis issues that links different modalities and models - Includes a series of appendices and tutorial-style chapters that makes even the most sophisticated approaches accessible







Development of Methods for Directed and Structured Immobilization of Biomolecules


Book Description

Surface immobilized molecules play a crucial role in applied as well as in basic research. They can be found in DNA or protein-array as well as in cell-migration or biochemical interaction experiments. Especially for proteins the immobilization can critically affect molecule accessibility and activity. In this work two essential aspects of protein immobilization were investigated: the identification of suitable surface functionalization by two array approaches and the generation of laterally structured gray scale protein patterns by projection lithography. In proof-of-concept experiments a new strategy to create an array of different, neighboring functionalizations on the same surface was successfully tested. In "mechanical protection" inert plungers were applied to protect distinct surface areas from the surface functionalization reagents and allowed a selective modification of individual regions in serial reactions. In a particle based alternative approach a high spot density surface array was fabricated using functionalized, polyvinyl acetate, melamine and silicon oxide-based particles. The in situ encoded bead-based array (IEBA) allowed the study of immobilization conditions and the effect of protein adhesion. For the reliable and fast analysis of array-images with several thousand individual particles a custom open-source evaluation software was developed. To create protein patterns a custom-built projection lithography device was utilized to generate high definition protein patterns. Patterning conditions were optimized with respect to deposition speed and signal to noise ratio while retaining a biocompatible process flow. The established technology provides protein patterns with great control over the deposited surface density, patterns were transferred within seconds to minutes to functionalized glass slides. To obtain three-dimensional, surface-functionalized surfaces this approach was transferred to thin polymer films. The substrates were demonstrated to be biocompatible with mouse fibroblasts. These surfaces allow a novel level of control addressing both the chemical surrounding and the shape of a cell microenvironment.




Autophagy: Lower Eukaryotes and Non-Mammalian Systems, Part A


Book Description

This is the companion volume to Daniel Klionsky's Autophagy: Lower Eukaryotes, which features the basic methods in autophagy covering yeasts and alternative fungi. Klionsky is one of the leading authorities in the field. He is the editor-in-chief of Autophagy. The November 2007 issue of Nature Reviews highlighted his article, "Autophagy: from phenomenology to molecular understanding in less than a decade. He is currently editing guidelines for the field, with 230 contributing authors that will publish in Autophagy.Particularly in times of stress, like starvation and disease, higher organisms have an internal mechanism in their cells for chewing up and recycling parts of themselves. The process of internal "house-cleaning in the cell is called autophagy – literally self-eating. Breakthroughs in understanding the molecular basis of autophagy came after the cloning of ATG1 in yeast. These ATG genes in yeast were the stepping stones to the explosion of research into the molecular analysis of autophagy in higher eukaryotes. In the future, this research will help to design clinical approaches that can turn on autophagy and halt tumor growth. - Establishes the functional roles of specific cellular proteins in selective and nonselective autophagy in mammalian cells, which aides researchers in determining why autophagy is shut down in neoplastia (growth of abnormal tissue mass) and turned on during bacterial invasion - Includes methods to evaluate the role of autophagy in the drug-induced cell death of cancer cells in culture, which helps researchers design clinical approaches that can turn on autophagy and halt tumor growth - Covers higher eukaryotes including lifespan in C.elegans to marine organisms and bridging into the clinical aspects, including autophagy in chronic myelogenous leukemia (CML is one of four types of leukemia), lung cancer, prostate cancer, and cardiac cells
