pDsRed-Monomer-F Vector

DsRed-Monomer is soluble when expressed in mammalian cells

DsRed-Monomer is soluble when expressed in mammalian cells. HeLa cells were transfected with pDsRed-Monomer-N1 and fixed in 4 paraformaldehyde 24 hr post-transfection. DsRed-Monomer fluorescent protein displays an even, consistent, and homogeneous distribution.

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.

DsRed-Monomer is a monomeric protein

DsRed-Monomer is a monomeric protein. Panel A. Recombinant DsRed-Express and DsRed-Monomer fluorescent proteins (100 μg) were analyzed by FPLC gel filtration chromatography. Overall absorbance (A280) and chromophore excitation (A557) of the eluted material were monitored simultaneously. DsRed-Monomer elutes from the column at a retention time (39 min) corresponding to a molecular weight of 28 kDa. The calculated molecular weight of DsRed-Monomer is 26.8 kDa. DsRed-Express is a tetrameric protein that elutes at an earlier retention time (33 min) corresponding to a molecular weight of 89 kDa. Panel B. 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, DsRed-Monomer fluorescent protein 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 boiled (denatured) counterpart due to its tetrameric structure.
