Gxstrands emerged from a global supply scarcity of long-chain single-stranded DNA. Given the high cost of single-stranded DNA made by using existing chemical or enzymatic methods, there was a necessity to develop an alternative production method in order to enable basic research and then also development of commercial products that use single-stranded DNA. Initially, the demand came from material science and nanotechnology applications, but it turns out that single-stranded DNA has probably its greatest potential as starting material and also as active substance in genomic medicines. Today we offer our novel and proprietary fermentation-based technology for scalable single-stranded DNA manufacturing that ensures sequence flexibility and high quality, and removes previous limitations on scalability.
