Product Information

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

DescriptionThe 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

ApplicationsLive cell imaging
Visualizing actin dynamics
Actin as biomarker or control
SpecificityActin microfilaments in human, rodent and plant cells, zebrafish, Toxoplasma gondii
Vector typeMammalian expression vector
PromoterConstitutive CMV IE
Codon usageMammalian
Nuclear localization signal (NLS)No
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
