Title
Proton relaxation enhancement by means of serum albumine and poly-L-lysine labeled with : relaxivities as function of molecular weight and conjugation efficiency
Author
Abstract
A series of poly-L-lysine chains, with molecular weight ranging from 3300 up to 102,000 Da, were labeled with DTPA-Gd3+. No significant differences in longitudinal and transversal relaxivity, could be demonstrated as a function of the chain length. The R1 and R2 relaxivities were respectively 2.5 and 5 times superior to those of plain DTPA-Gd3+ (at 2.4 T). Bovine serum albumin was also labeled in a way that a wide (DTPA-Gd3+)/BSA range (3-39) was obtained. The longitudinal relaxivity, of these paramagnetically labeled albumins, increased with increasing (DTPA-Gd3+)/BSA ratios. This effect was most pronounced at very low (DTPA-Gd3+)/BSA ratios.
