Abstract

Disclosed herein are a DNA aptamer specifically binding to pLDH ( Plasmodium Lactate Dehydrogenase), a composition for the diagnosis of malaria, comprising the same, and a diagnostic kit for malaria using the same. Superior in specificity and stability to antibodies which are conventionally used to diagnose malaria, the DNA aptamers specifically binding to pLDH ( Plasmodium Lactate Dehydrogenase) in accordance with the present invention can be developed into biosensors which determine pLDH levels with high sensitivity and accuracy, greatly contributing to the diagnostic accuracy of malaria.

Claims (7)

1. A DNA aptamer specifically binding to pLDH (plasmodium lactate dehydrogenase), wherein the DNA aptamer comprises a base sequence having a homology of 70% or higher with SEQ ID NO: 1 or 2.

2. A composition for diagnosis of malaria comprising the DNA aptamer of claim 1 .

3. A diagnostic kit of malaria using comprising the DNA aptamer of claim 1 .

4. A method of diagnosis of malaria, the method comprising:

providing the DNA aptamer of claim 1 ;

contacting the DNA aptamer with a sample comprising pLDH (plasmodium lactate dehydrogenase) selected from the group consisting of pvLDH (plasmodium vivax lactate dehydrogenase), pfLDH (plasmodium falciparum lactate dehydrogenase), pmLDH (plasmodium malariae lactate dehydrogenase), poLDH (plasmodium ovale lactate dehydrogenase) and a combination thereof; and

detecting a complex of the DNA aptamer and pLDH.
