Using in vitro selection, high affinity DNA aptamers to the food allergen Lup an 1, ß-conglutin, were selected from a pool of DNA, 93 bases in length, containing a randomised sequence of 49 bases. ß-conglutin was purified from lupin flour and chemically crosslinked to carboxylated magnetic beads. Peptide mass fingerprinting was used to confirm the presence(More)
The rapid and sensitive detection of small molecules is garnering increasing importance, and aptamers show great promise in replacing expensive, elaborate detection platforms exploiting chromatographic separation or antibody-based assays. The characterization of aptamer interaction with small molecule targets is not facile, and there is a mature need for a(More)
