    摘要： This invention relates to the delivery of agents to the body. One particular class of such agents are contrast agents useful in medical imaging techniques. The agents may be metals useful as contrast agents in magnetic resonance imaging (MRI), or in nuclear imaging, including positron emission tomography (PET), or as therapeutic agents in radiotherapy. The agents may alternatively be contrast agents useful in X-ray imaging. The invention also relates to methods by which agents for delivery to the body can be coupled to carriers and to targeting moieties effective to direct the agent to a specific locus within the body.

    摘要： A process is provided for the preparation of albumin which has extremely low levels of or is essentially free of colorants, metal ions, human proteins, host proteins, fragments of albumin, polymers or aggregates of albumin and viruses, and which is essentially non-glycated, relatively high in free thiol and with an intact C-terminus. The process comprises passing albumin (preferably expressed and secreted by transformed yeast) through positive mode cation exchange and then positive mode anion exchange chromatography. Other steps may also be employed, ultrafiltration, gel permeation chromatography, affinity chromatography binding the albumin by using blue dyes) and affinity chromatography binding contaminants by using an aminophenylboronic acid resin. Elution of albumin, with a compound having affinity for albumin, from a material having no specific affinity for albumin is also disclosed, as is removal of ammonium ions with a counter-ion.
