Biotech Support Group Release: BindPro™ Cited in U.S. Patent 20120296189 Titled Methods of Collecting and Analyzing Samples

Published: Dec 03, 2012

Dec 02, 2012 - MONMOUTH JUNCTION, NJ.– Inventors John Bhogal, Alva Karinka, Timothy Henning, David Cunningham, Udo Hoss, Andrew Naegeli, John Latour and assignee Abbott Diabetes Care Inc published United States Patent Application 20120296189 titled, Methods of Collecting and Analyzing Samples. The patent cites BindPro™ from Biotech Support Group and details a method for measuring interstitial fluid glucose concentration via ion chromatography. The patent describes methods for measuring analyte concentrations in interstitial fluid samples and methods of extracting interstitial fluid.

The NERL D-Glucose standard of known concentration assay method was implemented to determine the concentration of glucose in samples. Standard solutions were prepared by adding volume of NERL D-Glucose standard solution with DI water followed by mixing and transfer to a microfuge tube. BindPro™ suspension was added to the tube and the filtrate was placed on an autosampler vial. Duplicate standard solutions were prepared with different concentrations and volumes. For clinical sample preparation, human interstitial fluid (ISF) in aqueous benzoic acid solution was frozen until ion chromatography analysis. The clinical samples are thawed and BindPro™ is added and filtrate is transferred to the autosampler vial. The samples are prepared for ion chromatography injection sequence for analyzing interstitial fluid samples.

Characteristics Of BindPro™ Metabolomics - Protein Removal & Enrichment of Metabolites/Analytes From Serum or Plasma

§ Protein removal >95% from serum, plasma, tissue etc.

§ Linearly scaleable, unlike chemical precipitation or membrane filtration.

§ Fast process, less than 30 minutes from application to separation

§ Applicable for drug binding/screening and metabolomics

§ Removes proteins from many species including human, mouse, sheep, bovine, goat, rat, and calf

§ The process could be scaled up or down.

§ The bound protein can be eluted from the surface quantitatively.

§ It is supplied as dry powder.

§ Compatible with high throughput systems such as 96 well plate.

BindPro™ is an umbrella trademark for polymeric reagents designed as alternative to ultrafiltration and solvent precipitation for applications that require protein removal and/or concentration in a more versatile or scaleable format. BindPro™ can be used in lieu of solvents for drug binding studies, especially useful for analytes or metabolites.
