LingVitae’s ‘genetic binary code’

Overview: Norwegian start-up LingVitae is developing a tool to translate biological data of interest into a form that can be more readily detected. It’s using a restriction and ligation enzyme system to cleave two end bases at a time from target DNA fragments of around 4- 40 bases[1], and effectively replace such two base combinations with predetermined, longer sequences of DNA (or DNA bound to labels), which are then concatenated into a new and much longer DNA strand. The process can be thought of as making a genetic binary code, where A, T, G, and C are replaced with, for example, 0-0, 0-1, 1-0, and 1-1 (where 0’s and 1’s correspond to distinct 10-base-long units). The resulting DNA concatemers would be amenable to hybridization with probe oligonucleotides[2]. In addition, a similar overall method could be used to convert protein sequences into nucleic acid sequences for detection[3]. Continue reading
