摘要： The present invention relates to recombinant albumins fused with poly-cysteine peptide and methods for preparing the same, more precisely recombinant albumins in which cysteines that can be used for drug binding are amplified at N-terminal and C-terminal of the albumin and methods for preparing the same. The recombinant albumin of the present invention demonstrates improved albumin-drug conjugation efficiency when it is used for drug delivery system, indicating that it can effectively deliver a large amount of drug to a target tissue. At the same time, the recombinant albumin of the present invention can be used as an excellent drug deliverer with reduced side effects, compared with the conventional albumin carriers, by regulating the amount of drug conjugated to each unit of albumin by regulating the number of cysteine fused thereto. In addition, the recombinant albumin of the present invention can be used for the screening of a novel drug and for the non-invasive real-time diagnosis and treatment of disease by combining with a fluorescent material or a contrast agent for molecular imaging.
