Detecting small amounts of analytes, especially antibodies, presents a significant challenge in high-throughput methods. Fortunately, nucleic acid amplification techniques provide a promising solution. We have successfully developed and tested an innovative technology for detecting anti-glycan antibodies, utilizing a printed glycan array combined with a rolling circle amplification reaction based on the ABO blood group antibody model. This breakthrough has dramatically enhanced the sensitivity of our immunoassay, improving it by over an order of magnitude and allowing us to detect concentrations as low as 1 ng/ml. This advancement opens new approaches for research and clinical applications, making previously undetectable analytes accessible for study.
