pAcGFP1-Tubulin Vector

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.
