摘要:
The transformation yield of electroporation is increased by using higher DNA concentrations and DNA affinity purification. Fusion proteins of a viral coat protein variant and a heterologous polypeptide are useful in phage display systems.
摘要:
The invention provides a recombinant targeted bacteriophage for expressing a transgene in a target cell transduced with the bacteriophage. The bacteriophage comprises a first nucleic acid sequence encoding a pill capsid minor coat protein that is configured to display a cell-targeting ligand for enabling delivery of the bacteriophage to a target cell, a second nucleic acid sequence encoding at least one pVIII capsid major coat protein that is configured to display a foreign peptide thereon, and a transgene which encodes a protein which exerts a biological effect on the target cell.
摘要:
The invention provides a targeted bacteriophage-polymer complex comprising a recombinant targeted-bacteriophage and a cationic polymer. The complex has a net positive charge. The invention provides methods of preparing bacteriophages and complexes thereof, and to their uses for the delivery of transgenes in a variety of gene therapy applications.
摘要:
The present invention provides a composition for treating a bacterial biofilm, comprising a first bacteriophage that is capable of infecting a bacterium within said biofilm, and a first polysaccharide lyase enzyme that is capable of degrading a polysaccharide within said biofilm. The composition preferably further comprises a pharmaceutically-acceptable antimicrobial agent, and may also include a DNase. Also provided are modified bacteriophages, methods of creating modified bacteriophages, use of said compositions and bacteriophage for treating biofilms, and methods for treating biofilms using the bacteriophages and compositions of the invention.
摘要:
A method for identifying suitable targets for antibacterial agents based on identifying targets of bacteriophage-encoded proteins is described. Also described are compositions useful in the identification methods and in inhibiting bacterial growth, and methods for preparing and using such compositions.
摘要:
Filamentous phage particles displaying a ligand on their surface are used to deliver a therapeutic gene to a cell. The ligand is a fusion protein with a phage capsid protein, covalently conjugated to phage particles, or complexed with modified phage particles.
