Lili Wang, Paul Patrone, Anthony Kearsley, Jerilyn Izac, Adolfas Gaigalas, John Prostko, Hang Xie, Linhua Tian, Elzafir Elsheikh, Edward Kwee, Troy Kemp, Simon Jochum, Natalie Thornburg, Clifford McDonald, Adi Gundlapalli, Sheng Lin-Gibson
COVID-19 has highlighted the need for more accurate and reproducible measurements of humoral immunity, including antibody levels and neutralization potential, which are critical for diagnostics, seroprevalence estimates, and development of vaccines and

Quantitation and integrity evaluation of RNA genome in lentiviral vectors by direct reverse transcription-droplet digital PCR (direct RT-ddPCR)

September 2, 2023
Author(s)
Zhiyong He, Edward Kwee, Megan Cleveland, Kenneth Cole, Sheng Lin-Gibson, Hua-Jun He
Abstract Lentiviral vectors (LV) have proven to be powerful tools for stable gene delivery in both dividing and non-dividing cells. Approval of these LVs for use in clinical applications has been achieved by improvements in LV design. Critically important

Large Field of View Quantitative Phase Imaging of Induced Pluripotent Stem Cells and Optical Pathlength Reference Materials

February 23, 2018
Author(s)
Edward J. Kwee, Alexander W. Peterson, Jeffrey R. Stinson, Michael W. Halter, Liya Yu, Michael P. Majurski, Joe Chalfoun, Peter Bajcsy, John T. Elliott
Induced pluripotent stem cells (iPSCs) are reprogrammed cells that can have heterogeneous biological potential. Quality assurance metrics of reprogrammed iPSCs will be critical to ensure reliable use in cell therapies and personalized diagnostic tests. We
