Whole-genome Identification of Transcriptional Start Sites by Differential RNA-seq in Bacteria

Authors: Ramón Cervantes-Rivera and Andrea Puhar, date: 09/20/2020, view: 1461, Q&A: 0

Gene transcription in bacteria often starts some nucleotides upstream of the start codon. Identifying the specific Transcriptional Start Site (TSS) is essential for genetic manipulation, as in many cases upstream of the start codon there are ...

Plaque Assay to Determine Invasion and Intercellular Dissemination of Shigella flexneri in TC7 Human Intestinal Epithelial Cells

Authors: Atin Sharma and Andrea Puhar, date: 07/05/2019, view: 2685, Q&A: 0

Shigella flexneri invades the epithelial cells lining the gut lumen and replicates intracellularly. The specialized Type III Secretion System (T3SS) and its effector proteins, encoded on a large virulence plasmid, assist the bacterium to ...

Quantification of Neisseria meningitidis Adherence to Human Epithelial Cells by Colony Counting

Authors: Sara Sigurlásdóttir, Sunil D Saroj, Olaspers Sara Eriksson, Jens Eriksson and Ann-Beth Jonsson, date: 02/05/2018, view: 5509, Q&A: 0

To cause an infection, the human specific pathogen Neisseria meningitides must first colonize the nasopharynx. Upon tight interaction with the mucosal epithelium, N. meningitidis may cross the epithelial cellular barrier, reach the ...

Cytosolic and Nuclear Delivery of CRISPR/Cas9-ribonucleoprotein for Gene Editing Using Arginine Functionalized Gold Nanoparticles

Authors: Rubul Mout and Vincent M. Rotello, date: 10/20/2017, view: 9117, Q&A: 1

In this protocol, engineered Cas9-ribonucleoprotein (Cas9 protein and sgRNA, together called Cas9-RNP) and gold nanoparticles are used to make nanoassemblies that are employed to deliver Cas9-RNP into cell cytoplasm and nucleus. Cas9 protein is ...

Chromatographic Assays for the Enzymatic Degradation of Chitin

Authors: Sophanit Mekasha, Tina R. Tuveng, Gustav Vaaje-Kolstad and Vincent G. H. Eijsink, date: 05/05/2021, view: 32, Q&A: 0

Chitin is an insoluble linear polymer of β(1→4)-linked N-acetylglucosamine. Enzymatic cleavage of chitin chains can be achieved using hydrolytic enzymes, called chitinases, and/or oxidative enzymes, called lytic polysaccharide

Polyamine Transport Assay Using Reconstituted Yeast Membranes

Authors: Sarah van Veen, Shaun Martin, Marleen Schuermans and Peter Vangheluwe, date: 01/20/2021, view: 1103, Q&A: 0

ATP13A2/PARK9 is a late endo-/lysosomal P5B transport ATPase that is associated with several neurodegenerative disorders. We recently characterized ATP13A2 as a lysosomal polyamine exporter, which sheds light on the molecular identity of the unknown
