High efficiency cell-specific targeting of cytokine activity

Cell-specific targeting by engineered M13 bacteriophage expressing VEGFR2 nanobody

Objective(s): Filamentous bacteriophage M13 was genetically engineered to specifically target mammalian cells for gene delivery purpose. Materials and Methods: A vascular endothelial growth factor receptor 2 (VEGFR2)-specific nanobody was genetically fused to the capsid gene III of M13 bacteriophage (pHEN4/3VGR19). A mammalian expression construct containing Cop-green fluorescent protein (Cop-G...

High Efficiency Diffusion Molecular Retention Tumor Targeting

Here we introduce diffusion molecular retention (DMR) tumor targeting, a technique that employs PEG-fluorochrome shielded probes that, after a peritumoral (PT) injection, undergo slow vascular uptake and extensive interstitial diffusion, with tumor retention only through integrin molecular recognition. To demonstrate DMR, RGD (integrin binding) and RAD (control) probes were synthesized bearing ...

Engineering High-Affinity T Cell Receptor/Cytokine Fusions for Therapeutic Targeting

Analysis of biological selections for high-efficiency gene targeting.

A two-marker selection system that allows the efficient isolation of diploid gene knockouts by two sequential rounds of targeted homologous recombination has been developed. A systematic evaluation of the biological parameters that govern the selection process showed that a successful strategy must match the expression level of the target gene, the efficacy of the marker, and the selection stri...

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
