The Fuse-It Technology Fusogenic Liposome Endocytotic Liposome Liposomal Carrier Lipoplex Membrane Fusion FUSION Lipofection ENDOCYTOSIS IMMEDIATE RELEASE INTO THE CYTOPLASM Endosome Fuse-It Membrane Fusion Is Superior to Lipofection ENDOSOMAL RELEASE Basic principle: The Fuse-It liposomal carrier simply fuses with the cell membrane, then releases the included molecule of interest directly into the cytoplasm. This results in immediate and efficient transfer without processes such as endocytosis, lysosomal degradation, and mitosis. LYSOSOMAL DEGRADATION Lysosome Cardiomyocytes T cells Macrophages Endothelial cells Supreme biocompatibility: In contrast to classical lipofection reagents, the Fuse-It reagents are non-toxic. Even sensitive and difficult-totransfect cells, such as primary neurons, keratinocytes, and stem cells, retain high viability with maximized fusion efficiency.

Fuse-It-P Immediate Transfer of Soluble s Deliver your protein of interest directly into living cells without the interfering effects of artificial overexpression Perform functional imaging, such as speckle analysis, FRAP, or single molecule analysis Fuse-It-P Controlled quantity: Fuse-It-P is optimized for the efficient transfer of low to intermediate amounts of water-soluble proteins. Instant activity: s are freed directly into the cytoplasm within 1 20 minutes. Efficient transfer: No lysosomal degradation can occur, which is in contrast to endosomal uptakedepending protein transfection methods. Versatile application: Use the most suitable buffer for your protein. Burgstaller, G., et al., Multidimensional immunolabeling and 4D time-lapse imaging of vital ex vivo lung tissue.

Phase Contrast Infrared Control Dye R-Phycoerythrin Efficiency and Easy Visualization CHO-K1 cells directly after fusion with Fuse-It-P and R-Phycoerythrin. Note: When using Fuse-It-P, the amount of transfected protein is much less in comparison to plasmid DNA or transfection. Since there is no amplification of the delivered proteins, the fluorescence signal of a transfected reporter protein, such as GFP, is generally weak. What seems to be a disadvantage for fluorescence microscopy is a benefit for protein functionality: when using Fuse-It-P, the proteins are delivered at a physiological level without artificial overexpression, keeping their natural functionality inside the living cell.

LifeAct Visualization of F-Actin in Living Cells Brilliantly visualize F-actin with unrestricted functionality no interference with cytoskeletal dynamics in vitro and in vivo LifeAct, a 17-amino acid peptide, is derived from a protein found in Saccharomyces cerevisiae. It stains filamentous actin (F-actin) structures in living or fixed eukaryotic cells and tissues with excellent signal-to-noise ratio. Z-stack of HT-1080 LifeAct-TagGFP2 cells in a 3D hydrogel environment. LifeAct Plasmid After transient or stable transfection of cells with the LifeAct plasmid, F-actin can be brilliantly visualized using the fluorescence markers GFP2 or RFP. Please note: The LifeAct Plasmid is not compatible with the available Fuse-It products. LifeAct Adenoviral and Lentiviral Vectors The LifeAct viral vectors are especially suited for difficult-to-transfect cells and for the generation of stable cell lines. They mediate efficient transduction, integration, and longterm expression into dividing and non-dividing cells, both in vitro and in vivo. LifeAct The recombinant LifeAct is especially useful for very fast staining of F-actin in living cells. In fixed cells, it represents the non-toxic alternative to phalloidin. Stable LifeAct Expressing Cell Line The stable human fibrosarcoma cell line HT-1080 LifeAct-TagGFP2 allows perfect visualization of highly dynamic F-actin, which is ideal for studies on migration, chemotaxis, and wound healing.
