TY - JOUR AU - Kim, Yong-Sam AB - Targeting aberrant glycoforms has been validated for in vitro cancer diagnostic development, and several assays are currently in routine clinical use. Because N-glycans in Fc region of antibodies show cross-reactivity with various lectins, high-quality aglycosylated antibodies are exceptionally important for immunoassay platform-based quantitative measurements. Previously, aglycosylated antibody acquisition relied on incomplete, uneconomical and onerous enzymatic and chemical methods. Here, we edited four murine immunoglobulin G genes using adenine base-editing and homology-directed recombination (HDR)-mediated gene editing methods to generate aglycosylated antibody-producing mice. Resulting aglycosylated antibodies showed required analytical performances without compromised protein stability. Thus, this aglycosylated monoclonal antibody-lectin coupled immunoassay for the quantification of tumour markers (ALIQUAT) method can provide a robust, versatile and accessible immunoassay platform to quantify specific glycoforms in precision cancer diagnostics. Moreover, the engineered mice can be used as a host to produce various aglycosylated antibodies in a convenient and robust fashion, thereby expanding in vitro diagnostic development opportunities that utilize glycoforms as a disease-specific biomarkers.
