Background:

Mapping co-localized proteins at the sub-cellular level is crucial for understanding biological processes.
Current immuno-fluorescence microscopy techniques for protein mapping exhibit signal variability across runs.
Standardization of multiplexed bioimaging (MBI) data is essential for reliable downstream analysis.

Purpose of the Study:

To compare various normalization protocols for MBI data.
To propose a robust normalization technique for MBI data acquired using the Toponome Imaging System (TIS).
To enhance the consistency and comparability of MBI data across different experimental runs.

Main Methods:

Comparative analysis of different normalization protocols for MBI data.
Development and validation of a novel normalization technique for TIS data.
Evaluation of normalization performance using expert assessment (pathologists and biologists) and quantitative metrics (Kullback-Leibler divergence).

Main Results:

The proposed normalization method demonstrated consistent results on TIS MBI data.
Expert evaluation by pathologists and biologists favored the normalization results produced by the proposed method.
The method achieved higher between-class KL divergence and lower within-class KL divergence for cell phenotypes in colorectal cancer and normal samples.

Conclusions:

A robust normalization technique for MBI data from the TIS has been developed and validated.
The proposed method effectively reduces data variability, enabling more reliable analysis of cell phenotypes.
This standardization is critical for advancing research in complex diseases like colorectal cancer using high-content bioimaging.
