dc.description.abstract | β-Casomorphin-7 (BCM-7), a seven amino acid peptide, is released during digestion of β-casein A1 variant of milk which is speculated to be associated with certain diseases. Fifteen ssDNA aptamers having high affinity toward BCM-7 were identified from a 72 nt long random library after ten rounds of systematic evolution of ligands by exponential enrichment. Dissociation constant values of selected aptamers were in the range of 7.7–156.7 nM. Seq6 aptamer exhibited the lowest Kd value. Nine aptamers were evaluated for their binding toward BCM-7, BCM-9A1, and BCM-9A2 peptides, and binding was variable. SeqU5 exhibited the lowest binding with BCM-9A1 and BCM-9A2. Aptamer-coated gold nanoparticles (GNPs) resulted in color change of GNPs in the presence of BCM-7, thereby establishing recognition of BCM-7 by aptamers. The enzyme-linked aptamer-sorbent assay (ELASA) was evaluated as an assay of BCM-7 in biological fluids. BCM-7-peroxidase competed with BCM-7 in ELASA, performed with BCM-7 solution and BCM-7 spiked urine pretreated with urease, plasma, and β-casein digest samples. | en_US |
