1,2-distearoyl-sn-glycero-3-phosphoethanolamine-polyethylene glycol is a PEG-modified lipids. It is a long circulating liposome membrane,formation of micelles in water dispersion,the critical micelle concentration(CMC)ratio of surfactant is 102 times lower,so the drug stability is better, even by hemodilution,can maintain the integrity of the micelle particle,has certain targeting, easy accumulation in solid tumors.Tetramethylrhodamine (TMR,TRITC)has been a widely used fluorophore for preparing bioconjugates, especially fluorescent antibody and avidin derivatives used in immunochemistry.Under the name TAMRA,the carboxylic acid of 6-TAMRA has also achieved prominence as a dye for oligonucleotide labeling and automated DNA sequencing applications.
