Researchers have introduced an advanced method for labeling proteins in intact tissues, addressing a longstanding challenge in biological research. The technique, designed to ensure even distribution of antibodies across entire organs, has been demonstrated across multiple tissue types. This approach could significantly improve the accuracy of cellular studies by preserving tissue structure while enabling more precise protein detection. Scientists expect the method to aid in the study of complex biological systems, providing insights into cellular functions without altering the natural architecture of tissues. Breakthrough in Protein Labeling According to a study published in Nature Biotechnology, the technique, known as continuous redispersion of volumetric equilibrium (CuRVE), was developed at the Massachusetts Institute of Technology (MIT). The research team, led by Kwanghun Chung, Associate Professor of Chemical Engineering and Neuroscience at MIT, tested the method on various biological samples, including rodent and human tissues. By controlling the speed of antibody-antigen interactions and enhancing molecular diffusion through stochastic electrotransport, the process allowed for uniform protein labeling in a fraction of the time required by conventional methods.
