摘要: Genetically engineered reporters have revolutionized the understanding of many biological processes. MRI-based reporter genes can dramatically improve our ability to monitor dynamic gene expression and allow coregistration subcellular genetic information with high-resolution anatomical images. We developed a biocompatible MRI based on human gene, protamine-1 (hPRM1). The arginine-rich hPRM1 (47% arginine residues) generates high contrast chemical exchange saturation transfer (CEST) mechanism. 51 amino acid- long protein was fully synthesized using microwave-assisted technology, CEST characteristics this were compared other CEST-based agents. Both bacterial cells express an optimized showed higher controls. Live expressing embedded in three-dimensional culture, also generated wild-type live cells.
