Alternative Method for HDL and Exosome Isolation with Small Serum Volumes and Their Characterizations

open access: yesSeparations, 2021
High-density lipoprotein (HDL) and exosomes are promising sources of biomarkers. However, the limited sample volume and access to the ultracentrifuge equipment are still an issue during HDL and exosome isolation.

A three-component theory of sedimentation equilibrium in a density gradient [PDF]

open access: yes, 1961
In the original analysis (1) of the behavior of macromolecules and viruses in a density gradient at equilibrium in the ultracentrifuge, only two incompressible components were considered to be present.

Encapsulation of Small Extracellular Vesicles into Selectively Disassemblable Shells of PEGylated Metal‐Phenolic Networks

open access: yesAdvanced Healthcare Materials, EarlyView.
Small extracellular vesicles (sEVs) are encapsulated into protective shells composed of metal‐phenolic networks (MPNs) and secondary poly(ethylene glycol) layers. This surface modification approach enhances the storage stability of sEVs while maintaining their integrity and functionality. The shells can be selectively disassembled under mild conditions.

CLDN18.2 CAR‐derived Extracellular Vesicle Immunotherapy Improves Outcome in Murine Pancreatic Cancer

open access: yesAdvanced Healthcare Materials, EarlyView.
CLDN18.2 CAR‐T cell‐derived small extracellular vesicles (CAR‐sEVs) display potent cytotoxicity and prolong survival in preclinical pancreatic cancer models. They contain functional CAR proteins and granzyme B, exhibit antigen specificity, and effectively target tumor cells while sparing healthy cells.

Cytoplasmic DNA in the unfertilized sea urchin egg: Physical properties of circular mitochondrial DNA and the occurrence of catenated forms [PDF]

open access: yes, 1968
The mitochondrial DNA in the unfertilized egg of the sea urchin Lytechinus pictus is present in an amount approximately seven times that of the haploid nuclear DNA.(1) The mitochondrial DNA has a higher buoyant density than the nuclear DNA and consists ...

Effect of Nanoparticle Rigidity on the Interaction of Stromal Membrane Particles with Leukemia Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Cell membrane nanoparticles made with stromal cells are prepared and used to target leukemia cells. Deposition of the cell membrane onto rigid silica cores leads to increased uptake both in leukemia cell lines and primary cells from patients. These results show that nanoparticle rigidity affects the interaction between cell membrane nanoparticles and ...

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
