  Nuclear Actin-Chromobody®plasmid

  Visualize the actin dynamics in real time in the nucleus with the nuclear Actin-Chromobody®. Upon transformation, your cells express the nuclear Actin-Chromobody® and transport the nuclear Actin-Chromobody into the nucleus. The nuclear cytoskeleton is visualized in real time by binding of the fluorescent Chromobody® to Actin.Actin-Chromobody®

  

Nuclear Actin live cell imaging

 

  Courtesy of Matthias PlessnerNIH 3T3 cells (murine fibroblasts) transfected with the nuclear Actin-Chromobody® (TagGFP2, green) and the Lamin-Chromobody® (TagRFP2, red) were starved in serum-free medium for 24 hours. Nuclear Actin-Chromobody-probed endogenous F-actin assembly and distribution is shown 30 s after stimulation with serum.

  Trace actin dynamics in cell nuclei non-invasively

  With the nuclear Actin-Chromobody® plasmid you obtain the sequence of the Alpaca antibody to Actin, also termed VHH-Actin or Actin-nanobody, fused to TagGFP (Evrogen) and a nuclear localization sequence (NLS). The transient binding does not influence cell viability or motility and thus offers you the unique possibility to observe the cytoskeleton in your cell nuclei.
