Cross-linked informofers

open access: yesNucleic Acids Research, 1979
The proteins of 30S RNP particles containing pre-mRNA (hnRNA) were cross-linked with bifunctional reagents (dimethyl-suberimidate and dimethyl-3,3'-dithiobispropionimidate). Further treatment with 1 or 2 M NaCl dissociates all RNA from protein. However, a significant part of protein particles--informofers being cross-linked survived high salt treatment.

Effect of the cross-linking agent on the cross-linking degree and electrical properties of cross-linked polyethylene

open access: yesMaterials Research Express, 2023
To study the effect of a cross-linking agent on the cross-linking degree and electrical properties of cross-linked polyethylene, different mass fractions of cross-linked polyethylene and their electrical properties were investigated.

An XPS Investigation of Thermal degradation and Charring of Cross-linked Polyisoprene and Polychloroprene [PDF]

open access: yes, 2001
Our interest in butadiene-containing polymers had led to an investigation of the thermal degradation of polyisoprene, PIP, and polychloroprene, PCP. The connection between cross-linking and thermal stability through an examination of PIP and PCP has been

Corneal collagen cross-linking

open access: yesMiddle East African Journal of Ophthalmology, 2010
Corneal collagen cross-linking (CXL) with riboflavin and ultraviolet-A (UVA) is a new technique of corneal tissue strengthening by using riboflavin as a photosensitizer and UVA to increase the formation of intra and interfibrillar covalent bonds by photosensitized oxidation.Keratocyte apoptosis in the anterior segment of the corneal stroma all the way ...

Enzymatic Cross-Linking of Dynamic Thiol-Norbornene Click Hydrogels [PDF]

open access: yes, 2019
Enzyme-mediated in situ forming hydrogels are attractive for many biomedical applications because gelation afforded by enzymatic reactions can be readily controlled not only by tuning macromer compositions, but also by adjusting enzyme kinetics.

Collagen cross linking: Current perspectives

open access: yesIndian Journal of Ophthalmology, 2013
Keratoconus is a common ectatic disorder occurring in more than 1 in 1,000 individuals. The condition typically starts in adolescence and early adulthood. It is a disease with an uncertain cause and its progression is unpredictable, but in extreme cases,

Interfacial Bioorthogonal Cross-Linking [PDF]

open access: yesACS Macro Letters, 2014
Described herein is interfacial bioorthogonal cross-linking, the use of bioorthogonal chemistry to create and pattern biomaterials through diffusion-controlled gelation at the liquid-gel interface. The basis is a rapid (k2 284000 M-1 s-1) reaction between strained trans-cyclooctene (TCO) and tetrazine (Tz) derivatives.
