摘要： A method for recovering a metal, capable of recovering a metal easily without requiring the use of an organic medium, is provided. A first complex between a first chelating agent and a metal present in a sample is formed in a first mixture prepared by mixing the first chelating agent and the sample. Then, the first complex is recovered from the first mixture, and a second complex between the metal derived from the first complex and a second chelating agent is formed in a second mixture prepared by mixing the first complex and an aqueous solution of the second chelating agent. The aqueous solution is under the pH conditions where the first chelating agent can be insoluble in the aqueous solution. Then, a liquid fraction containing the second complex is recovered from the second mixture. Thus, the metal can be recovered.

摘要： The current invention provides a method for directly converting histopathologically processed biological samples, tissues, and cells into a multi-use biomolecule lysate. This method allows for simultaneous extraction, isolation, solublization, and storage of all biomolecules contained within the histopathologically processed biological sample, thereby forming a representative library of said sample. This multi-use biomolecule lysate is dilutable, soluble, capable of being fractionated, and used in any number of subsequent experiments.
