Visualize Histones in live cells: Histone-Chromobody

Posted by Christoph Eckert on Aug 3, 2017 1:22:32 PM

The ChromoTek Histone-Chromobody®* is a novel probe to visualize endogenous histone H2A-H2B heterodimer in live cells:

  • Monitors chromatin dynamics
  • Tested in yeast, flies, and mammals
  • Non-invasive and real-time analysis

The Histone-Chromobody consists of a functional intracellular antibody, also called “nanobody”, VHH, or single domain antibody (sdAb), derived from alpaca. The VHH is genetically fused to enhanced Green Fluorescent Protein (EGFP).

After expression, the small 42 kDa Histone-Chromobody is a superior probe for real time analysis of endogenous H2A-H2B heterodimer in live cells. The Histone-Chromobody is optimized for live cell imaging and live cell microscopy.
