3M Poster Session

Gretchen presented her latest uFFE work at the 3M Poster Session on campus last week! The University, in partnership with 3M, hosts this annual event as an  opportunity for grad students and post-docs to share their research with industry-minded executives, scientists, and engineers from 3M.

Pittcon 2024

Gretchen traveled to San Diego last week to present her research at the 75th Annual Pittcon Conference, where she gave an oral presentation on her research progress, “An Online Micro Free Flow Electrophoresis Platform for Continuous Monitoring of Peptide Messengers.” It was a great week hearing from other analytical chemists and exploring San Diego with some Bühlmann & Stein group members!

Bowser Group Awarded NIH Grant

The Bowser group was recently awarded a $1.25 million NIH grant: Online Affinity Micro Free Flow Electrophoresis Assays for Continuous Monitoring of Biochemical Messengers!

Funding Agency:  National Institutes of Health (NIGMS)

Amount:  $1.25 million

Our goal is to develop an online, flow-through, affinity assay that can continuously monitor the efflux of biochemical messengers from dynamically changing biological systems in real time.  Microfluidic integration of a perfusion chamber, online mixing of affinity reagents and continuous micro free flow electrophoresis (µFFE) separations will directly address limitations that have prevented the development of time responsive affinity-based assays to date.  Continuous affinity µFFE assays will enable researchers to study how biochemical messenger systems (i.e. neurotransmission, energy regulation and immune response) change over time or respond to external stimuli.
