N-glutaryl phosphatidyl ethanolamine

N-glutaryl-phosphatidyl ethanolamine (NGPE) (Avanti Polar Lipids, Inc.). Stored at -80°C. 

Using N-terminus modified polylysine, we developed a synthesis for an amphiphilic polychelator, A,a-(DTPA-polylysyl)glutaryl phosphatidyl ethanolamine (DTPA-PL-NGPE). This polychelator was incorporated into the liposomal membrane and micelle core during liposome or micelle preparation. This system sharply increased the number of chelated Gd atoms attached to a single lipid anchor. This increased the number of bound reporter metal atoms per vesicle and decreased the dosage of an administered...
