ELISA Detection of Urine DEK to Predict and Diagnose Bladder Cancer in Humans

摘要

The present invention is directed to a method of detecting a DEK protein in a human urine sample using an ELISA assay. Methods and compositions for detection of DEK using mAb 260-6F9F6 (as detection antibody) and mAb 16-2C9C3 (as capture antibody) in human urine are provided herein. Specifically, the ELISA assay utilizes a capture mAb and a detection mAb to yield a high sensitivity of <50 ng/mL. The presence of DEK in urine is useful in predicting or diagnosing the occurrence of bladder cancer in humans.
