Background:

Protein post-translational modifications (PTMs) are crucial for cellular functions and implicated in diseases.
Current high-throughput methods like mass spectrometry (MS) and protein arrays have limitations.
Protein arrays are restricted by pre-purified proteins and high costs, while MS is limited by protein abundance.

Purpose of the Study:

To develop a novel, integrated microfluidic platform for analyzing multiple PTMs.
To overcome the limitations of existing protein array technologies.
To enable high-throughput PTM analysis using freshly synthesized proteins.

Main Methods:

Integration of microfluidics with in situ protein expression from a cDNA microarray.
Development of a modular integrated microfluidic platform for multiple PTM analysis (IMPA).
Demonstration of the system's capabilities for tyrosine phosphorylation and ubiquitination analysis.

Main Results:

The IMPA platform enables analysis of freshly synthesized protein arrays.
The system demonstrated potency, specificity, and flexibility in analyzing PTMs.
The approach utilizes minute biological samples and cost-effective technology.

Conclusions:

The IMPA platform addresses limitations of current PTM analysis technologies.
This novel approach offers unlimited design and protein composition flexibility.
The technology is applicable to basic, biomedical, and biomarker research.
