Can I use TOP10F' competent cells for transformation of my TOPO vector that contains the ccdB gene?
Strains that contain an F plasmid, such as TOP10F', are not recommended for transformation and selection of recombinant clones in any TOPO vector containing the ccdB gene. While the F plasmid does encode the CcdA protein, which acts as an inhibitor of the CcdB gyrase-toxin protein, the half-life of the CcdA protein is shorter than that of the CcdB protein. Overexpression of the CcdB protein causes cell death when its action is not prevented by sufficient CcdA.

Identification and functional analysis of the rat caspase-3 gene promoter.

Caspase-3 is the major effector in apoptosis triggered by various stimuli. Previous studies demonstrated a significant increase in transcriptional activity of the caspase-3 gene during neuronal apoptosis. Recent findings suggest that differential expression of the caspase-3 gene may underlie the regulation of apoptotic susceptibility during brain development and after acute ... More

Overcoming immune tolerance of the growth factors associated with tumor growth should be a useful approach to cancer therapy by active immunity. We used vascular endothelial growth factor (VEGF) as a model antigen to explore the feasibility of the immunogene tumor therapy with a vaccine based on a single xenogeneic ... More
