A High-Throughput Biochemical Fluorometric Method for Measuring HDL Redox Activity
- 技術優勢
- • More accurate indicator of cardiovascular risk• Inexpensive• Rapid• Scalable/high-throughput• Cell-free assay of HDL function
- 技術應用
- • Clinical heart disease diagnostic tool• Research heart disease diagnostic tool• HIV research• Autoimmune disease research
- 詳細技術說明
- Dr. Theodoros Kelesidis, Dr. Otto Yang, and Dr. Srinivasa Reddy have invented a method of measuring the functionality of HDLs by measuring their redox activity using the Amplex Red fluorochrome. This reproducible assay has a 96 well format, making it inexpensive, rapid, and suitable for high throughput screening applications. This invention can be used both in cardiovascular disease research to better understand the relationship between HDL redox activity and arthrosclerosis, and in clinical settings as a tool for measuring cardiovascular risk in patients. This technology has the additional potential to be used in the research of many systemic inflammatory diseases such as AIDS and autoimmune diseases, as there are also studies that correlate dysfunctional HDL with HIVi and rheumatoid arthritisii.

- *Abstract
-
UCLA researchers in the Department of Medicine have developed a method of screening for the functional properties of high-density lipoprotein (HDL) in the blood that may serve as a more accurate risk indicator of cardiovascular disease.

State Of Development
The assay has been fully developed and tested, with current work involving testing multiple patient populations and using the assay to study HDL function.
Background
Cardiovascular disease remains the number one cause of death for both men and women in the United States. According to a 2011 study by the Center for Disease Control, approximately 600,000 people die of heart disease in the United States every year, which is 1 in every 4 deathsi.HDLs and cardiovascular disease show an inverse correlation. However, growing evidence suggests that higher HDL levels are not always beneficial since the proteins can become dysfunctional. Current methods of HDL testing only indicate the overall levels in the blood and say nothing about their size, density, composition, and functionality. All of these properties are associated with atherosclerosis, and the ability to measure them could become a great tool for diagnosing cardiovascular risk.
