PHOTOCHEMISTRY OF PHYCOBILIPROTEINS [PDF]

, 1989
Native PEC from the cyanobacterium, Mastigocladus laminosus, and its isolated α-subunit show photoreversibly photochromic reactions with difference-maxima around 502 and 570 nm in the spectral region of the α-84 phycoviolobilin chromophore.

Single‐Virus Stochastic Biosensing: Proof of Concept for SARS‐CoV‐2 Detection in Complex Medium Using CMOS‐Based Nanocapacitor Arrays

Advanced Sensor Research, EarlyView.
SARS‐CoV‐2 particles in complex cell culture medium are detected using high‐frequency electrical measurements. This is made possible through the use of large arrays of independently addressable nanoelectrodes implemented using complementary metal oxide semiconductor (CMOS), semiconductor technology.

Factors affecting the integrity of high density lipoproteins in the ultracentrifuge

Journal of Lipid Research, 1982
Because of reported losses of apolipoproteins from high density lipoproteins during ultracentrifugation, we studied several factors that could affect the integrity of these lipoprotein complexes.

A lithium-ion battery based on a graphene nanoflakes ink anode and a lithium iron phosphate cathode

, 2014
Li-ion rechargeable batteries have enabled the wireless revolution transforming global communication. Future challenges, however, demands distributed energy supply at a level that is not feasible with the current energy-storage technology. New materials,

A SERS‐Based Antibody‐Aptamer Sandwich Assay for Extracellular Vesicle‐Associated Tau Detection Using Gold Nanoparticles

Advanced Sensor Research, EarlyView.
Tau protein plays a critical role in the pathology of Alzheimer's disease, utilizing extracellular vesicles (EVs) as a mechanism for intercellular transmission. This study develops a highly sensitive sandwich assay biosensor for detecting and quantifying tau‐associated EVs using surface‐enhanced Raman spectroscopy (SERS).

Separation of dog serum lipoproteins by ultracentrifugation, dextran sulfate precipitation, and paper electrophoresis*

Journal of Lipid Research, 1961
The separation of dog serum lipoproteins by ultracentrifugation at a density of 1.063 is hindered by the failure of the high density fraction to accumulate in the bottom portion of the centrifuge tube.

A simple protocol for the subcellular fractionation of skeletal muscle cells and tissue

BMC Research Notes, 2012
Background We describe a method for subcellular fractionation of mouse skeletal muscle, myoblast and myotubes to obtain relatively pure fractions of nuclear, cytosolic and mitochondrial compartments.

Nematic Ordering of Rigid Rods in a Gravitational Field

, 2003
The isotropic-to-nematic transition in an athermal solution of long rigid rods subject to a gravitational (or centrifugal) field is theoretically considered in the Onsager approximation.

Viral‐Mediated Connexin 26 Expression Combined with Dexamethasone Rescues Hearing in a Conditional Gjb2 Null Mice Model

Advanced Science, EarlyView.
AAV2.7m8 serotype combined with the gfaABC1D promoter targets infection of supporting cells (SCs). AAV2.7m8‐gfaABC1D‐Gjb2 administration to mice results in excessive immune responses. The combination of AAV2.7m8‐gfaABC1D‐Gjb2 with dexamethasone (DEX) shows a synergistic effect and enhances the gene therapy effect in a conditional Cx26 null mice model ...
