Method of identifying the molecules and molecules that home to a selected organ or tissue in vivo

摘要

The present invention provides an in vivo method for identifying molecules that home to a selected organ or tissue. In addition, the invention provides peptides that home to a selected organ or tissue. For example, the invention provides peptides that selectively home to an organ such as brain or kidney or to a tissue such as a tumor tissue. The invention further provides methods of using an organ homing molecule, for example, to target an agent such as a drug to a selected organ or to identify the target molecule expressed by the selected organ.
