Molecular diagnostic is a rapid developing field. With more and more biomarker, nowadays people are able to predict, diagnostic or tracing many diseases. Many people are focusing on how to increase the sensitivity of detection reagents or devices. But actually, the most important step is to catch DNA/RNA first. Because if we can’t catch those genes, even the detection method is extreme sensitive, we still can’t detect it. iCATCHER is focusing on get higher quality of DNA/RNA from Liquid Biopsy and Solid Biopsy because we know that DNA/RNA purification is the first step of achieving “Precision Medicine”.
