pAcGFP1-N2 Vector

Description

pAcGFP1-N2 encodes a green fluorescent protein fromAequorea coerulescens. pAcGFP1-N2 is designed for studies in mammalian systems. This vector allows expression of a protein of interest as an N-terminal fusion to AcGFP1. The fusion vector can also be used as a cotransfection marker since the unmodified vector will express fluorescent protein. The fluorescent protein coding sequence in this construct has been human-codon-optimized for efficient expression and enhanced brightness in mammalian cells.

Each vector contains a hygromycin selection cassette. These vectors can be used together with our standard N1/C1 vectors containing the neomycin selection cassette to establish double stable cell lines expressing two different Living Colors proteins. Back 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 4C and not boiled prior to loading on a gel. Boiled and unboiled recombinant proteins 7.5 mug 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. Back Back Use of AcGFP1 for fusions and fluorescence microscopy applications.Panels AandB. 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 mug/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. Back
