A cell-based multiplex immunoassay platform using fluorescent protein-barcoded reporter cell lines.
(Communications biology, 2021-11)Multiplex immunoassays with acellular antigens are well-established based on solid-phase platforms such as the Luminex® technology. Cell barcoding by amine-reactive fluorescent dyes enables analogous cell-based multiplex ... -
A chemical glycoproteomics platform reveals O-GlcNAcylation of mitochondrial voltage-dependent anion channel 2.
(Cell Rep, 2013-10-31)Protein modification by O-linked β-N-acetylglucosamine (O-GlcNAc) is a critical cell signaling modality, but identifying signal-specific O-GlcNAcylation events remains a significant experimental challenge. Here, we describe ... -
Biomimetic nanoparticles with enhanced affinity towards activated endothelium as versatile tools for theranostic drug delivery.
(Theranostics, 2018-01-05)Activation of the vascular endothelium is characterized by increased expression of vascular adhesion molecules and chemokines. This activation occurs early in the progression of several diseases and triggers the recruitment ... -
Deep-tissue SWIR imaging using rationally designed small red-shifted near-infrared fluorescent protein.
(Nature methods, 2023-01)Applying rational design, we developed 17 kDa cyanobacteriochrome-based near-infrared (NIR-I) fluorescent protein, miRFP718nano. miRFP718nano efficiently binds endogenous biliverdin chromophore and brightly fluoresces in ... -
Features of programmed cell death in intact Xenopus oocytes and early embryos revealed by near-infrared fluorescence and real-time monitoring.
(Cell Death Differ, 2010-01)Factors influencing apoptosis of vertebrate eggs and early embryos have been studied in cell-free systems and in intact embryos by analyzing individual apoptotic regulators or caspase activation in static samples. A novel ... -
First-in-human intraoperative near-infrared fluorescence imaging of glioblastoma using cetuximab-IRDye800.
(Journal of neuro-oncology, 2018-08)<h4>Introduction</h4>Maximizing extent of surgical resection with the least morbidity remains critical for survival in glioblastoma patients, and we hypothesize that it can be improved by enhancements in intraoperative tumor ... -
Hand-held spectroscopic device for in vivo and intraoperative tumor detection: contrast enhancement, detection sensitivity, and tissue penetration.
(Anal Chem, 2010-11-01)Surgery is one of the most effective and widely used procedures in treating human cancers, but a major problem is that the surgeon often fails to remove the entire tumor, leaving behind tumor-positive margins, metastatic ... -
Identification of fluorescent beads using a coded aperture snapshot spectral imager.
(Appl Opt, 2010-04-01)We apply a coded aperture snapshot spectral imager (CASSI) to fluorescence microscopy. CASSI records a two-dimensional (2D) spectrally filtered projection of a three-dimensional (3D) spectral data cube. We minimize a convex ... -
Relationship of T2-Weighted MRI Myocardial Hyperintensity and the Ischemic Area-At-Risk.
(Circ Res, 2015-07-17)RATIONALE: After acute myocardial infarction (MI), delineating the area-at-risk (AAR) is crucial for measuring how much, if any, ischemic myocardium has been salvaged. T2-weighted MRI is promoted as an excellent method to ... -
Robust approaches to quantitative ratiometric FRET imaging of CFP/YFP fluorophores under confocal microscopy.
(J Microsc, 2009-01)Ratiometric quantification of CFP/YFP FRET enables live-cell time-series detection of molecular interactions, without the need for acceptor photobleaching or specialized equipment for determining fluorescence lifetime. Although ... -
Role of iPLA(2) in the regulation of Src trafficking and microglia chemotaxis.
(Traffic (Copenhagen, Denmark), 2011-07)Microglia are immune effector cells in the central nervous system (CNS) and their activation, migration and proliferation play crucial roles in brain injuries and diseases. We examined the role of intracellular ... -
The evolving capabilities of rhodopsin-based genetically encoded voltage indicators.
(Curr Opin Chem Biol, 2015-08)Protein engineering over the past four years has made rhodopsin-based genetically encoded voltage indicators a leading candidate to achieve the task of reporting action potentials from a population of genetically targeted ... -
The pallial basal ganglia pathway modulates the behaviorally driven gene expression of the motor pathway.
(Eur J Neurosci, 2007-04)The discrete neural network for songbird vocal communication provides an effective system to study neural mechanisms of learned motor behaviors in vertebrates. This system consists of two pathways--a vocal motor pathway ... -
Thermodynamic analysis of ligand-induced changes in protein thermal unfolding applied to high-throughput determination of ligand affinities with extrinsic fluorescent dyes.
(Biochemistry, 2010-12-28)The quantification of protein-ligand interactions is essential for systems biology, drug discovery, and bioengineering. Ligand-induced changes in protein thermal stability provide a general, quantifiable signature of binding ...
