Abstract: Provided are isolated antibodies, and fragments and derivatives thereof, which bind to tumor antigens. Also provided are compositions and delivery agents that include the disclosed antibodies and fragments and derivatives thereof; cells that produce the same; methods for producing the same; methods of using the same for detecting, targeting, and/or treating tumors and/or metastatic cells derived therefrom and/or tumor stem cells; and methods for predicting the recurrence of cancer in a subject.
Abstract: The invention comprises curing polyamic acid solutions into polyimide solutions by adding a hydrophilic reagent to a polyamic acid solution. The hydrophilic reagent is selected to have little or no reactivity with amines or carboxylic acids, and is of the type that will react with water to form by-products that shift the equilibrium between polyamic acid as a reactant and polyimide and water as products toward the production of polyimide.
