A comparison of Lyse-It to other cellular sample preparation, bacterial lysing, and DNA fragmentation technologies
(PLOS, 2019-07-23)The ability for safe and rapid pathogenic sample transportation and subsequent detection is an increasing challenge throughout the world. Herein, we describe and use bead-beating, vortex, sonication, 903 protein saver ... -
Quantitative high-throughput screening assays for the discovery and development of SIRPα-CD47 interaction inhibitors
(PLOS, 2019-07-05)CD47 is an immune checkpoint molecule that downregulates key aspects of both the innate and adaptive anti-tumor immune response via its counter receptor SIRPα, and it is expressed at high levels in a wide variety of tumor ... -
Escherichia Coli FeoC Binds a Redox-Active, Rapidly Oxygen-Sensitive [4Fe-4S] Cluster
(2019-02-07)The acquisition of iron is essential to establishing virulence among most pathogens. Under acidic and/or anaerobic conditions, most bacteria utilize the widely-distributed ferrous iron (Fe²⁺) uptake (Feo) system to import ... -
Distorted perovskites for high voltage dielectric capacitors
(SPIE, 2019-05-13)There are several mechanisms which have been proposed for the existence of colossal dielectric constant in the class of perovskite calcium copper titanate (CaCu₃Ti₄O₁₂ or CCTO) materials. Researches indicate that existence ... -
Design of materials for IR detectors using high Z elements for high energy radiation environment
(SPIE, 2019-05-13)There is a strong need for rad hard and high operating temperature IR detectors for space environment. Heavy metal Selenides (high Z and large density) have been investigated for more than half century for high operating ... -
The Crystal Structure of Klebsiella pneumoniae FeoA Reveals a Site For Protein-Protein Interactions
(2019-01-08)In order to establish infection, pathogenic bacteria must obtain essential nutrients such as iron. Under acidic and/or anaerobic conditions, most bacteria utilize the Feo system in order to acquire ferrous iron (Fe²⁺) from ... -
