Paulo W. Pires 1, Fabrice Dabertrand 2, Scott Earley 1
1Department of Pharmacology, University of Nevada School of Medicine, 2Department of Pharmacology, University of Vermont College of Medicine

This manuscript describes a simple and reproducible protocol for isolation of intracerebral arterioles (a group of blood vessels encompassing parenchymal arterioles, penetrating arterioles and pre-capillary arterioles) from mice, to be used in pressure myography, immunofluorescence, biochemistry, and molecular studies.

In Vitro Characterization of Histone Chaperones using Analytical, Pull-Down and Chaperoning Assays
Ruchir C. Bobde *1,2, Ketul Saharan *1,2, Somanath Baral 1,3, Surajit Gandhi 1,2, Archana Samal 1,2, Rajivgandhi Sundaram 1, Ashish Kumar 1,4, Ajit K. Singh 1,5, Aritreyee Datta 1, Dileep Vasudevan 1
1Institute of Life Sciences, 2Regional Centre for Biotechnology, 3School of Biotechnology, KIIT University, 4Department of Molecular Biophysics and Biochemistry, Yale University, 5Department of Pharmacology, University of Vermont College of Medicine

This protocol describes a battery of methods that includes analytical size-exclusion chromatography to study histone chaperone oligomerization and stability, pull-down assay to unravel histone chaperone-histone interactions, AUC to analyze the stoichiometry of the protein complexes, and histone chaperoning assay to functionally characterize a putative histone chaperone in vitro.
