Production of Disulfide-stabilized Transmembrane Peptide Complexes for Structural Studies Pooja Sharma1,2, Mariam Kaywan-Lutfi1, Logesvaran Krshnan1,2, Eamon F. X. Byrne1,2, Melissa Joy Call1,2, Matthew Edwin Call1,2 1Structural Biology Division, The Walter and Eliza Hall Institute of Medical Research, 2The University of Melbourne Biophysical and biochemical studies of interactions among membrane-embedded protein domains face many technical challenges, the first of which is obtaining appropriate study material. This article describes a protocol for producing and purifying disulfide-stabilized transmembrane peptide complexes that are suitable for structural analysis by solution nuclear magnetic resonance (NMR) and other analytical applications.
Isolation and Analysis of Brain-sequestered Leukocytes from Plasmodium berghei ANKA-infected Mice Victoria Ryg-Cornejo1, Lisa J. Ioannidis1, Diana S. Hansen1 1The Walter and Eliza Hall Institute of Medical Research A method for isolation of adherent inflammatory leukocytes from brain blood vessels of Plasmodium berghei ANKA-infected mice is described. The method allows quantification as well as phenotypic characterization of isolated leukocytes after staining with fluorescent antibodies and subsequent analysis by flow cytometry.
Using Bioluminescent Imaging to Investigate Synergism Between Streptococcus pneumoniae and Influenza A Virus in Infant Mice Kirsty R. Short1, Dimitri A. Diavatopoulos2, Patrick C. Reading1, Lorena E. Brown1, Kelly L. Rogers3, Richard A. Strugnell1, Odilia L.C. Wijburg1 1Department of Microbiology and Immunology, University of Melbourne, 2Laboratory of Pediatric Infectious Diseases, Radboud University Nijmegen Medical Centre, 3The Centre for Dynamic Imaging, The Walter and Eliza Hall Institute for Medical Research A concurrent infection with influenza A virus is one of the factors implicated in the induction of invasive pneumococcal disease during asymptomatic Streptococcus pneumoniae carriage. Here we describe a mixed infection method using infant mice to investigate the synergism between these two respiratory pathogens.
