Abstract
The present invention relates to a method by which one can target an undesired target molecule or target antigen, preferably a protein. The method comprises the intracellular expression of an antibody capable of binding to the target. A DNA sequence is delivered to a cell, the DNA sequence contains a sufficient number of nucleotides coding for the portion of an antibody capable of binding to the target operably linked to a promoter that will permit expression of the antibody in the cell(s) of interest. The antibody is then expressed intracellularly and binds to the target, thereby disrupting the target from its normal actions.
Claims5
An antibody, wherein the antibody contains a secretory signal and further contains an intracellular retention sequence.
A single chain antibody, wherein the antibody does not contain a secretory signal, and wherein the single chain antibody contains an intracellular localization sequence.
