By complete coincidence, some Hungarian scientists stumbled upon something that could change the world of pharmaceuticals.

Researchers have developed a method using bioorthogonal chemistry to create stable covalent bonds between proteins and fluorescent markers. This approach allows for selective labeling of target proteins in complex biological environments without interfering with natural cellular processes. The method has shown promising results in various proteins, achieving a 62% labeling rate for the BRD2 protein. It opens new avenues for studying biomolecular interactions and could have potential medical applications, including drug delivery systems. The findings were published in Angewandte Chemie International Edition.
