Abstract
The present invention provides a nucleic acid aptamer specifically recognizing β-lactoglobulin and use thereof. The nucleic acid aptamer has a sequence as shown in SEQ ID NO:1, a sequence having 60% or higher homology to the sequence as shown in SEQ ID NO:1 and specifically recognizing β-lactoglobulin, or a sequence derived from the sequence as shown in SEQ ID NO:1 and specifically recognizing β-lactoglobulin. The nucleic acid aptamer specifically binds to the allergen β-lactoglobulin in cow milk and dairy products, thereby providing a new tool for the high-sensitivity and low-cost detection of the allergen β-lactoglobulin.
