Bacterial flagellar capping proteins adopt diverse oligomeric states

open access: yeseLife, 2016
Flagella are crucial for bacterial motility and pathogenesis. The flagellar capping protein (FliD) regulates filament assembly by chaperoning and sorting flagellin (FliC) proteins after they traverse the hollow filament and exit the growing flagellum tip.

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

open access: yesAdvanced 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).

Quantitation of serum lipoproteins by electrophoresis on agarose gel: standardization in lipoprotein concentration units (mg/100 ml) by comparison with analytical ultracentrifugation

open access: yesJournal of Lipid Research, 1971
Lipoprotein electrophoresis on agarose gel has been modified to allow estimation of the absolute quantity of each fraction. The reproducibility of the method is illustrated by 12 determinations in a single day on serum from one normal subject: mean total

Spa47 is an oligomerization-activated type three secretion system (T3SS) ATPase from \u3cem\u3eShigella flexneri\u3c/em\u3e [PDF]

open access: yes, 2016
Gram-negative pathogens often use conserved type three secretion systems (T3SS) for virulence. The Shigella type three secretion apparatus (T3SA) penetrates the host cell membrane and provides a unidirectional conduit for injection of effectors into host
