Falsely diagnosed thyrotoxicosis caused by anti-streptavidin antibodies and pre-wash procedures

open access: yesThyroid Research, 2021
Background Anti-streptavidin antibodies are causal determinants of analytical interference during Thyroid function tests, and numerous reports have detailed such interference, with anti-streptavidin antibodies attracting attention.

Recombinant subunit vaccines against Neospora caninum [PDF]

open access: yes, 2007
The intracellular protozoan parasite Neospora caninum is an important cause of bovine abortion and congenital infection in many countries. Currently there is no effective control method available, and development of a vaccine has been suggested as a ...

Oligonucleotide immobilization on micropatterned streptavidin surfaces [PDF]

open access: yesNucleic Acids Research, 2000
We describe a simple procedure for photolithographic patterning of streptavidin on silicon substrates. Long wavelength UV (365 nm) light was used to direct the covalent attachment of photoactivatable biotin onto silylated silicon wafers. Fluorescently labeled streptavidin was found to bind only in areas exposed to the light.

Engineering tandem VHHs to target different epitopes to enhance antibody‐dependent cell‐mediated cytotoxicity

open access: yesFEBS Open Bio, EarlyView.
Tandem VHH targeting distinct EGFR epitopes were engineered into a monovalent bispecific antibody (7D12‐EGA1‐Fc) with more potent ADCC without increasing affinity to EGFR. Structural modeling of 7D12‐EGA1‐Fc showed cross‐linking of separate EGFR domains to enhance CD16a engagement on NK cells.

Optoelectronic sensitization of carbon nanotubes by CdTe nanocrystals [PDF]

open access: yes, 2009
We investigate the photoconductance of single-walled carbon nanotube-nanocrystal hybrids. The nanocrystals are bound to the nanotubes via molecular recognition.

Alcohol‐induced altered glycans in human tracheal epithelial cells promote bacterial adhesion

open access: yesFEBS Open Bio, EarlyView.
Alcohol induces altered glycans to promote bacteria adhesion. Heavy alcohol drinking is known to increase the risk of bacterial pneumonia. However, the link between alcohol levels and risk of infection remains underexplored. Recently, we found that alcohol induced α2‐6sialo mucin O‐glycans in human tracheobronchial epithelial cells, which mediated the ...

Secretion of streptavidin from Bacillus subtilis [PDF]

open access: yesApplied and Environmental Microbiology, 1993
Streptavidin is an extracellular tetrameric protein produced by Streptomyces avidinii. A series of hybrid gene fusions consisting of Bacillus signal peptide coding regions fused to the mature streptavidin sequence were constructed. B. subtilis strains harboring these plasmids accumulate a tetrameric streptavidin in the growth medium.

Next‐Generation Bio‐Reducible Lipids Enable Enhanced Vaccine Efficacy in Malaria and Primate Models

open access: yesAdvanced Functional Materials, EarlyView.
Structure–activity relationship (SAR) optimization of bio‐reducible ionizable lipids enables the development of highly effective lipid nanoparticle (LNP) mRNA vaccines. Lead LNPs show superior tolerability and antibody responses in rodents and primates, outperforming approved COVID‐19 vaccine lipids.

Non-specific cellular uptake of surface-functionalized quantum dots

open access: yes, 2010
We report a systematic empirical study of nanoparticle internalization into cells via non-specific pathways. The nanoparticles were comprised of commercial quantum dots (QDs) that were highly visible under a fluorescence confocal microscope.

Peptide Sequencing With Single Acid Resolution Using a Sub‐Nanometer Diameter Pore

open access: yesAdvanced Functional Materials, EarlyView.
To sequence a single molecule of Aβ1−42–sodium dodecyl sulfate (SDS), the aggregate is forced through a sub‐nanopore 0.4 nm in diameter spanning a 4.0 nm thick membrane. The figure is a visual molecular dynamics (VMD) snapshot depicting the translocation of Aβ1−42–SDS through the pore; only the peptide, the SDS, the Na+ (yellow/green) and Cl− (cyan ...
