We are interested in understanding low frequency somatic mutation in cancer tissues. This article introduces the application for low frequency mutation detection method based on our Sanger sequencing in angioimmunoblastic lymphoma test, providing a basis for applying this method to other disease tests. Currently there are low frequency mutation detection methods such as quantitative PCR, digital PCR, and NGS.
But there's no report on detection of IGHV7-3 low frequency mutation based on Sanger sequencing, of which detection limit is only 5%to 20%Generally due to technical limitations, low frequency detection based on Sanger sequencing cannot be accurately quantified. Our technique offers high sensitivity, low cost, and strong flexibility, making it an ideal choice for low frequency mutation detection. We are planning to design pseudogene primers as well as multiplex GCR primers to explore their application in blood diseases.
