Direct Synthesis of High‐Valence Protein@UiO‐66 Composites: Linking Crystallization Pathways to Protein Encapsulation

Advanced Materials, EarlyView.
This work reports a direct, biocompatible method to synthesize UiO‐66, enabling one‐step encapsulation of proteins without compromising crystallinity or activity. Using advanced in situ and ex situ techniques, the study reveals that proteins integrate concurrently with MOF growth, forming crystalline protein@UiO‐66 nanoparticles, and provide insight ...

Detection of Glycosylated and Deglycosylated Extensin Precursors by Indirect Competitive ELISA [PDF]

Plant Physiology, 1987
A competitive indirect enzyme-linked immunosorbent assay (ELISA) was developed for the rapid quantitation of the glycosylated and deglycosylated forms of the monomeric soluble extensin precursor subunits P1 and P2. A log-linear response range for each kind of precursor in the competition curve was between 0.01 and 100 nanograms per milliliter.

Perfusion Bioreactor Culture Incorporating Mechanical Confinement Enhances Mesenchymal Stem Cell Extracellular Vesicle Production and Wound Healing Potential

Advanced Materials Technologies, EarlyView.
Scalable manufacturing challenges and limited potency remain two of the most intransigent issues limiting clinical translation of EV therapeutics. Mechanical cues can induce phenotypic changes and increased vesiculation in EV source cells without the use of extraneous reagents, chemicals, and/or cargo, thereby potentially drastically improving the ...
