    摘要: The invention includes a method for determining the differences between the molecular interactions of two different mixtures of molecules and identifying ligands specific for molecules in one mixture. The method utilizes a combinatorial library to compare the molecular interactions of the two mixtures and eliminates those interactions that are common to both mixtures and those that are unique to the first mixture, such that interactions essentially unique to the target mixture are identified. Ligands specific for molecules in the target mixture can then be identified. The invention also includes a method of screening a combinatorial library to distinguish between true positive beads and false positive beads and to provide for the identification of ligands specific for target molecules.

    摘要: The invention includes a cell-growth-on-bead assay for screening a one-bead-one-compound combinatorial bead library to identify synthetic ligands for cell attachment and growth or proliferation of epithelial cells. Cells are incubated with a compound bead library for 24 to 72-hours, allowing them to attach and grow on the beads. Those beads with cells growing are removed, and the ligand on the bead is identified. Also provided are ligands specific for epithelial cancer cells. The invention also includes a method of capturing epithelial cells from body fluids. In this method, beads are prepared with a known ligand specific for a particular type of cell and incubated for 24 to 72 hours with a sample of the body fluid being tested. Those cells attached to the beads are removed and identified.

    摘要: The present invention provides amphiphilic telodendrimers that aggregate to form nanocarriers characterized by a hydrophobic core and a hydrophilic exterior. The nanocarrier core may include amphiphilic functionality such as cholic acid or cholic acid derivatives, and the exterior may include branched or linear poly(ethylene glycol) segments. Nanocarrier cargo such as hydrophobic drugs and other materials may be sequester in the core via non-covalent means or may be covalently bound to the telodendrimer building blocks. Telodendrimer structure may be tailored to alter loading properties, interactions with materials such as biological membranes, and other characteristics.
