pAcGFP1-Nuc Vector
pAcGFP1-Nuc encodes a humanized green fluorescent protein (GFP) derived from Aequorea coerulescens. The fluorescent protein is fused at its C-terminus to three copies of the nuclear localization signal (NLS) of the SV40 T-antigen. This vector is designed a marker for visualizing the nucleus in living or fixed cells by fluorescence microscopy.
Use of AcGFP1 for fusions and fluorescence microscopy applications
Use of AcGFP1 for fusions and fluorescence microscopy applications. Panels A and B. Activation of Protein Kinase C alpha was monitored with Living Colors AcGFP1. Panel A. HEK 293 cells were stably transfected with a plasmid encoding AcGFP1 fused to PKC alpha. Panel B. Cells were induced with 1.5 µg/ml PMA for 3 min. The PKC alpha-AcGFP1 fusion moves from the cytosol to the plasma membrane, a result consistent with the known mobilization pattern of PKC alpha. Panel C. HeLa cells were transiently transfected with pAcGFP1-Actin and visualized by fluorescence microscopy.
AcGFP1 is a monomeric protein
AcGFP1 is a monomeric protein. Panel A. Recombinant AcGFP1 protein was analyzed by FPLC gel filtration chromatography. Overall protein absorbance (A280) and chromophore excitation (A477) of the eluted material were monitored simultaneously. AcGFP1 elutes from the column at a retention time corresponding to a molecular weight of 24 kDa. The calculated molecular weight of AcGFP1 is 26.9 kDa. Panel B. Recombinant AcGFP1 protein was analyzed by sucrose density ultracentrifugation using a continuous gradient. Panel C. Pseudonative gel analysis of proteins. The oligomeric structure of proteins is preserved during SDS-PAGE analysis if samples are kept at 4°C and not boiled prior to loading on a gel. Boiled and unboiled recombinant proteins (7.5 μg) were separated by SDS-PAGE electrophoresis (12% acrylamide). In both the boiled (denatured) and unboiled (nondenatured) samples, AcGFP1 runs as a uniform band of ~30 kDa due to its monomeric structure. The unboiled (nondenatured) DsRed-Express runs at a much higher molecular weight than its denatured (boiled) counterpart due to its oligomeric structure.
AcGFP1 is ideal for multicolor and fluorescence microscopy applications
AcGFP1 is ideal for multicolor and fluorescence microscopy applications. AcGFP1 and DsRed2 protein fusions were transiently transfected and visualized by fluorescence microscopy. Panel A. pAcGFP1-Mito (mitochondria) and pDsRed2-Nuc (nucleus) in HEK 293 cells. Panel B. pAcGFP1-Golgi (Golgi apparatus) and pDsRed2-Nuc (nucleus) in HEK 293 cells.
Organelles targeted by the subcellular localization vectors
Organelles targeted by the subcellular localization vectors.
Subcellular localization vectors encode fusions of fluorescent proteins with localization signals or subcellular structural proteins, which target the fluorescent protein to a specific organelle or subcellular structure
Subcellular localization vectors encode fusions of fluorescent proteins with localization signals or subcellular structural proteins, which target the fluorescent protein to a specific organelle or subcellular structure. The vectors are available in a variety of organelle- and cytoskeleton-targeted color variants.
