Detecting Protein Arginine Deiminase (PAD) Activity in Human Tissues and SERA

Description:

Reference #: 00844

Background

The abundance of citrullinated proteins in human tissue has become a hallmark of many diseases, including cancer, rheumatoid arthritis, colitis, and multiple sclerosis. Proteins are citrullinated by a class of enzymes termed Protein Arginine Deiminases (PADs), which convert peptidyl-arginine to peptidyl-citrulline through an enzymatic reaction called deimination. Developing PAD inhibitors has become a focus of much research due to the apparent roles of PADs in the aforementioned diseases.

Invention Description:

Dr. Paul Thompson and his research team have developed a novel, easy, straightforward method of measuring PAD activity in mammalian tissue using a solution based assay suitable for a 96-well microplate. The method was developed using mouse tissue and sera, but can readily be adapted to human tissue and sera.

Potential Applications:

The ability to rapidly screen for dysregulated PAD activity in human tissues and sera will provide for early detection and diagnosis of PAD-related diseases.

Advantages and Benefits:

The developed method is simple and straightforward and can be adapted for human tissue and serum with little difficulty. The invention therefore creates a remarkable tool for detecting disease incidence and progression, as well as disease severity.
