Convenient diagnostics for lab and point-of-care.

New platform technology for detecting antibodies and protein biomarkers in clinical samples.

About Us

Solutions

image9

  • Researchers at the University of Calgary have created a fast, inexpensive point-of-care technology for the detection of biomarkers of infectious and chronic diseases in clinical samples. This innovative method has a high degree of specificity and sensitivity, without any need for sample preparation or purification and all this in a timely manner.
  • Our TreAsure Assay technology is based on enzyme complementation and produces glucose as a signalling molecule, which can be easily measured with a glucometer. This glucose level is proportional with antibodies/biomarkers in the sample. Frequent testing and support by a smart phone app allows you to follow up on the stage of the infection or disease and take action.

Technology

TreAsure Assays

Creative Protein Solutions (CPS) has created biosensors for infectious diseases and inflammation biomarkers, using the patent-pending TreAsure Assay technology, developed at the University of Calgary. 


This new approach relies on split enzyme complementation and produces glucose as the signalling molecule, which can be easily measured using existing or custom made glucometers. 

The enzyme trehalase (TreA), split into two non-functional fragments, is fused to specific sensing elements. For detecting antibodies, the enzyme fragments are fused with specific antigens. For detecting biomarkers of chronic disease other sensing elements are incorporated. Binding of the sensing element to the antibodies or biomarkers leads to complementation and activation of TreA, which will catalyse the hydrolysis of the substrate trehalose, resulting into glucose molecules.


Lab-based TreAsure Assays convert glucose into a colorimetric signal. 

Point-of-Care TreAsure Assays are integrated with existing or CPS's own glucometer technology.
