Exploring the Causes of Cancer
Queen's research to understand the regulation of a cell surface protein involved in cancer.
Measuring microRNAs in Blood to Speed Cancer Detection
A simple, ultrasensitive microRNA sensor holds promise for the design of new diagnostic strategies and, potentially, for the prognosis and treatment of pancreatic and other cancers.
Novel Proteins Linked to Huntington's Disease
University of Florida Health researchers have made a new discovery about Huntington's disease, showing that the gene that causes the fatal disorder makes an unexpected "cocktail" of mutant proteins that accumulate in the brain.
Enzyme Critical to Maintaining Telomere Length Discovered
New method expected to speed understanding of short telomere diseases and cancer.
New Method Identifies Up to Twice as Many Proteins and Peptides
An international team of researchers developed a method that identifies up to twice as many proteins and peptides in mass spectrometry data than conventional approaches.
Metabolic Profiles Distinguish Early Stage Ovarian Cancer with Unprecedented Accuracy
Studying blood serum compounds of different molecular weights has led scientists to a set of biomarkers that may enable development of a highly accurate screening test for early-stage ovarian cancer.
New Way to Force Stem Cells to Become Bone Cells
Potential therapies based on this discovery could help people heal bone injuries or set hardware, such as replacement knees and hips.
Long-Sought Protein Sensor for the ‘Sixth Sense’ Discovered
In a study led by scientists from The Scripps Research Institute (TSRI)the sensor protein for propioception has been identified.
How Viruses Commandeer Human Proteins
Researchers have produced the first image of an important human protein as it binds with ribonucleic acid (RNA), a discovery that could offer clues to how some viruses, including HIV, control expression of their genetic material.
Tracking How Herpes Simplex Virus Moves Through Cells
In a recent study, Derek Walsh, PhD, associate professor of Microbiology-Immunology, and his team showed how the herpes simplex virus (HSV) exploits microtubule plus-end tracking proteins to initiate transport and infection in human cells.

Novel ProteoPrep® 20 Immunoaffinity Depletion Resin for Human Plasma

Sigma Aldrich

The study of the human plasma proteome is an area of hugeimportance, especially for the pharmaceutical potential ofidentifying disease biomarkers. Many proteins of interestappear at low concentrations in the plasma and are, therefore,difficult to detect.

Identification of potential biomarkers is especially difficult dueto the presence of higher abundance proteins. To addressthese issues, an affinity resin has been developed for removalof 20 high abundance proteins from 8 µl of plasma. Depletionof these abundant proteins allows for visualization of proteinsthat co-migrate with, and are masked by, the high abundanceproteins during 1-D or 2-D gel electrophoresis andHPLC separations. Plasma proteins can then be loaded ontogels, IPG strips, or HPLC columns at higher levels for improvedvisualization/detection of low copy number proteins.
