Schaaf T, Li A, Grant B, Peterson K, Yuen S, Bawaskar P, et al.
Biosensors (Basel) . 2018 Oct; 8(4). PMID: 30352972
We have developed fluorescence resonance energy transfer (FRET) biosensors with red-shifted fluorescent proteins (FP), yielding improved characteristics for time-resolved (lifetime) fluorescence measurements. In comparison to biosensors with green and red...

Schaaf T, Peterson K, Grant B, Bawaskar P, Yuen S, Li J, et al.
SLAS Discov . 2016 Dec; 22(3):262-273. PMID: 27899691
A robust high-throughput screening (HTS) strategy has been developed to discover small-molecule effectors targeting the sarco/endoplasmic reticulum calcium ATPase (SERCA), based on a fluorescence microplate reader that records both the...

Schaaf T, Peterson K, Grant B, Thomas D, Gillispie G
SLAS Discov . 2016 Nov; 22(3):250-261. PMID: 27879398
We have developed a microplate reader that records a complete high-quality fluorescence emission spectrum on a well-by-well basis under true high-throughput screening (HTS) conditions. The read time for an entire...

Rebbeck R, Essawy M, Nitu F, Grant B, Gillispie G, Thomas D, et al.
SLAS Discov . 2016 Oct; 22(2):176-186. PMID: 27760856
Using time-resolved fluorescence resonance energy transfer (FRET), we have developed and validated the first high-throughput screening (HTS) method to discover compounds that modulate an intracellular Ca channel, the ryanodine receptor...

Petersen K, Peterson K, Muretta J, Higgins S, Gillispie G, Thomas D
Rev Sci Instrum . 2014 Nov; 85(11):113101. PMID: 25430092
We describe a nanosecond time-resolved fluorescence spectrometer that acquires fluorescence decay waveforms from each well of a 384-well microplate in 3 min with signal-to-noise exceeding 400 using direct waveform recording....

Gruber S, Cornea R, Li J, Peterson K, Schaaf T, Gillispie G, et al.
J Biomol Screen . 2014 Jan; 19(2):215-22. PMID: 24436077
We have used a "two-color" SERCA (sarco/endoplasmic reticulum calcium ATPase) biosensor and a unique high-throughput fluorescence lifetime plate reader (FLT-PR) to develop a high-precision live-cell assay designed to screen for...

Cornea R, Gruber S, Lockamy E, Muretta J, Jin D, Chen J, et al.
J Biomol Screen . 2012 Aug; 18(1):97-107. PMID: 22923787
Using fluorescence resonance energy transfer (FRET), we performed a high-throughput screen (HTS) in a reconstituted membrane system, seeking compounds that reverse inhibition of sarcoplasmic reticulum Ca-ATPase (SERCA) by its cardiac...

Gauer J, Sisk R, Murphy J, Jacobson H, Sutton R, Gillispie G, et al.
Biophys J . 2012 Aug; 103(2):238-46. PMID: 22853901
The C2A domain is one of two calcium ion (Ca(2+))- and membrane-binding domains within synaptotagmin I (Syt I), the identified Ca(2+) sensor for regulated exocytosis of neurotransmitter. We propose that...

Lloyd W, Wilson R, Chang C, Gillispie G, Mycek M
Biomed Opt Express . 2011 Jan; 1(2):574-586. PMID: 21258491
A fiber-optic system was developed to rapidly acquire tissue fluorescence wavelength-time matrices (WTMs) with high signal-to-noise ratio (SNR). The essential system components (473 nm microchip laser operating at 3 kHz...

Muretta J, Kyrychenko A, Ladokhin A, Kast D, Gillispie G, Thomas D
Rev Sci Instrum . 2010 Nov; 81(10):103101. PMID: 21034069
We describe a high-performance time-resolved fluorescence (HPTRF) spectrometer that dramatically increases the rate at which precise and accurate subnanosecond-resolved fluorescence emission waveforms can be acquired in response to pulsed excitation....
