CLEAR Technology: Advancing Protein Imaging and Precision Medicine

CLEAR Technology

Context

Recently, researchers at the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) with contributions from the Indian Institute of Science (IISc) developed CLEAR (Cleavable Light-Erased Antibody Reporter), a new imaging platform that enables detailed protein mapping within cells and tissues in biological samples and holds promise for biomedical research and precision medicine.

About CLEAR (Cleavable Light-Erased Antibody Reporter) Technology

  1. The platform enables imaging of multiple proteins within a single sample using a single fluorescent marker, overcoming a major challenge in spatial protein mapping.
  2. It employs a light-cleavable probe system that allows repeated cycles of protein labelling and imaging within the same spectral window.
  3. The fluorescent signal can be erased using a 365 nm LED light pulse, enabling successive rounds of protein analysis in the same sample.

Significance

  1. Facilitates the generation of high-resolution protein maps across specimens ranging from single cells to complex tissue sections.
  2. Combines high multiplexing capability, speed, spatial resolution, and compatibility with live biological samples, unlike conventional multiplex imaging methods.
  3. Holds potential for the early detection of cancers and neurological disorders.
  4. Enhances understanding of immune responses and cellular behaviour, supporting advanced biomedical research.
  5. Can contribute to precision medicine through detailed molecular profiling for targeted and personalised therapies.
