Indian Scientists Develop CLEAR Technology, Breakthrough Protein Imaging Platform for Precision Medicine

A scientific breakthrough comes as Indian researchers have developed the advanced imaging platform which called CLEAR (Cleavable Light-Erased Antibody Reporter). This will significantly improve the diagnosis of the diseases such as cancer, neurological disorders and immune related conditions. It is developed by scientists at Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), Bengaluru and it will allows the researchers to visualize the unprecedented number of proteins within the same biological sample using just a single fluorescent marker.

What is CLEAR Technology?

CLEAR (Cleavable Light-Erased Antibody Reporter) is the novel imaging technology which is designed to map the proteins inside biological samples with exceptional detail.

Proteins are among the most important molecules in the human body because they control nearly every biological function including the cell communication, immune responses, growth and repair.

In disease diagnosis, specially in cancer and neurological disorders, understanding where the proteins are located and how they interact inside the tissues is critically important.

Traditional this imaging methods struggle to visualize large numbers of proteins simultaneously and CLEAR solve this challenge.

Why Protein Mapping Matters in Disease Detection

Proteins serve as the key disease indicators.

A detailed protein map can help the doctors and researchers understand,

How the cancer cells behave
How immune cells respond to any infections
What changes occur in to neurodegenerative diseases
Which therapeutic targets may work best for individual

This field is called the spatial proteomics, where scientists study the protein identity and exact location inside tissues.

Accurate protein mapping can significantly improve the early diagnosis and treatment decisions.

How CLEAR Technology Works

The CLEAR platform uses the clever ‘erase and reuse’ concept. Think like as a chalkboard.

Scientists first label the specific proteins inside a biological sample by using fluorescent tags.

The sample is then imaged to be under a microscope.

After imaging, a gentle 365 nm LED light pulse is used to erase the fluorescent signal without damaging any part of the sample.

This same sample can then be relabelled with the new protein target and imaged again.

This cycle can be repeated multiple times.

This allows the scientists to create extremely detailed protein maps from the same sample.

What Makes CLEAR Different from Existing Technologies?

Current multiplex imaging methods faces the major limitations.

These includes the,

Requirement of a multiple fluorophores
Limited protein detection capacity
High technical complexity
Slower imaging workflows
Difficulty with the fragile biological samples

CLEAR offers the major advantages.

Key Benefits Are,

Uses only one fluorophore
Supports the high multiplex imaging
Works with a live cells
Provides high spatial resolution
Faster imaging workflow
Compatible with a delicate biological tissues
Enables virtually unlimited protein visualization

This makes the CLEAR as a potentially transformative innovation.

Who Developed CLEAR Technology?

The technology was developed by the researchers at Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), Bengaluru which is an autonomous institute under the Department of Science and Technology (DST).

The research team was led by the Prof. Sarit S. Agasti.

Key contributions included,

Probe design and a synthesis
Imaging workflow development
Experimental validation
Data analysis

Researchers from the Indian Institute of Science (IISc), Bengaluru has been collaborated in testing the platform in complex biological systems and specially immune cell applications.

The findings were published in the prestigious journal Chemical Science, which is published by the Royal Society of Chemistry.
