Validation Data Gallery

• 

  Nuclear Actin-Chromobody: NIH 3T3 cells (murine fibroblasts) transfected with the nuclear Actin-Chromobody (TagGFP2, green) and the Lamin-Chromobody (TagRFP, 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. Courtesy of Matthias Plessner.

Product Information

DNA plasmid encoding for anti-Actin VHH (anti-Actin Nanobody) fused to TagRFP.

• Description: The Actin-Chromobody allows imaging of actin dynamics in real-time in living cells.

  • Easily transfect your cells and non-invasively visualize actin cytoskeleton in real-time

  • Target and trace microfilaments in your cell line of interest

  • Use Actin-Chromobody as a marker of cellular morphology and as a probe for cellular motility

  • Actin-Chromobody has no notable effect cell viability or migration

• Applications: Live cell imaging; Visualizing actin dynamics; Actin as biomarker or control
• Specificity: Actin microfilaments in human, rodent and plant cells, zebrafish, Toxoplasma gondii
• Reporter: TagRFP
• Vector type: Mammalian expression vector
• Promoter: Constitutive CMV IE
• Codon usage: Mammalian
• Selection: Kan/Neo
• Nuclear localization signal (NLS): No
• Sequence: With the Actin-Chromobody plasmid you obtain the sequence of the Alpaca antibody to Actin fused to TagRFP or TagGFP2, as well as the full vector sequence.
• Transfection: Transfection of Chromobody plasmids into mammalian cells can be done with standard DNA-transfection methods, e.g. lipofection (Lipofectamine 2000® from Thermo Scientific), according to the manufacturer’s protocol for the transfection reagent. Please choose the transfection method that works the best for your cell type.
• Microscopy techniques: Wide-field epifluorescence microscopy; confocal microscopy; super-resolution microscopy e.g. STED
• Storage Condition: Shipped at ambient temperature. Store at -20 °C
