PLGA10K-PEG2K-Cys-Arg-Glu-Lys-Ala（CREKA）

Cys-Arg-Glu-Lys-Ala（CREKA)sequence has been identified as a tumor homing peptide,which can effectively bind to coagulation plasma protein.The results have been compared with the reported separation of CREKA(peptide without dye). It is found that fluorescein affects the energy distribution of the minimum energy conformation,and the repulsive spatial interaction produced by the dye shifts the energy distribution of the minimum energy conformation to a higher energy value.
