Isolation and Separation of Angiotensin I and II from Human Serum Using a New Chromatographic Matrix that Excludes High Molecular Weight Proteins
This innovation introduces a novel chromatographic matrix that effectively isolates and separates angiotensin I and II, key biomarkers involved in blood pressure regulation, from human serum. The system uses a hybrid combination matrix that selectively removes small molecular weight polypeptides while excluding large serum proteins. By integrating chelating...

Analytical Technology for the Isolation of 3-Nitrotyrosine as a Biomarker from Urine to Assess Depression and Acute Kidney Injury
This invention uses a novel separation technique to isolate specific biomarkers from urine, as a measure to detect and monitor depression and acute kidney injury (AKI). The system employs a hybrid chromatographic matrix that rejects biomolecules of specific sizes and allows only the desired small compounds, such as 3-nitrotyrosine (which has been linked...

Isolation of Protein Biomarkers from Saliva as a Technology to Assess and Monitor Cardiac Infarction
This technology introduces a novel separation method designed to isolate small protein biomarkers directly from saliva, enabling a rapid and non-invasive diagnostic approach for cardiac infarction. The system employs a hybrid chromatographic matrix that selectively rejects large proteins while allowing smaller biomarkers to interact with affinity sites...
