Product Information

DNA plasmid encoding for anti-Actin VHH (anti-actin Nanobody)with nuclear localization signal (NLS) fused to TagGFP2.

DescriptionThe nuclear 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

The nuclear Actin-Chromobody® plasmid has been published and described by Prof. Dr. Robert Grosse, Institute of Pharmacology, BPC, University of Marburg, Germany under license from ChromoTek:Matthias Plessner, Michael Melak, Pilar Chinchilla, Christian Baarlink, Robert Grosse (2015).

SequenceWith 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.
TransfectionTransfection 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 techniquesWide-field epifluorescence microscopy; confocal microscopy; super-resolution microscopy e.g. STED
Storage ConditionShipped at ambient temperature. Store at -20 °C
