Biomarkers Shared Resource

The Biomarkers Shared Resource is a component of the laboratory of Dr. Virginia Kraus.

This shared resource assists investigators with the design and implementation of molecular and protein assays to evaluate biochemical and inflammatory markers. In addition this shared resource specializes in analyses of joint tissue metabolites.  

Services include:

  • Training and education in biomarker analysis techniques
  • Advice in sample management and preparation as well as to the design for optimizing biomarker analyses
  • Biospecimens for pilot analyses to determine species specificity and feasibility of specific biomarker analyses
  • Collaboration: The Kraus laboratory maintains a strong interest in advancing the qualification of biomarkers for clinical use and welcomes any inquiries concerning potential collaborations to further this aim
