Lipid droplets are important organelles for the replication of several pathogens, including the Hepatitis C Virus (HCV). We describe a method to isolate lipid droplets for quantitative mass spectrometry of associated proteins; it can be used under a variety of conditions, such as virus infection, environmental stress, or drug treatment.
We present a genome engineering workflow for the generation of new in vitro models for HIV-1 infection that recapitulate proviral integration at selected genomic sites. Targeting of HIV-derived reporters is facilitated by CRISPR-Cas9-mediated, site-specific genome manipulation. Detailed protocols for single-cell clone generation, screening, and correct targeting verification are provided.
This protocol focuses on chromatin preparation from snap frozen tissues and it is suitable for Crosslinking Chromatin Immunoprecipitation (X-ChIP) followed by either quantitative PCR analysis (X-ChIP-qPCR) or next generation sequencing approaches (X-ChIP-seq).
