SQAG9, a new class of immunosuppressive sulfoquinovosylacylglycerol, and its biotinylated derivatives have been synthesized. A T7 Phage library, composed of random cDNA fragments from Drosophila melanogaster, displayed a possible binding peptide of 14 amino acids. The immobilized synthetic peptide on a sensor chip showed a dissociation constant of K-D = 1.5 x 10(-6) against SQAG9 in a surface plasmon resonance experiment. (C) 2004 Elsevier Ltd.
