U6 small nuclear RNA (snRNA) is an essential factor in mRNA splicing. On the basis of the high conservation of its sequence, it has been proposed that U6 snRNA may function catalytically during the splicing reaction. If this is the case, it is likely that U6 snRNA interacts with the splice sites in the spliceosome to catalyze the reaction. We have used UV crosslinking to analyze the interaction...

To enhance solubility and the performance of a plant gum (from south peach tree of China, SP gum) as a drilling fluid additive, we explored the potential of Modified SP (MSP) gum by modifying it with epichlorohydrin. The modification conditions, such as the mass ratio of  the crosslinking agent, pH and temperature, were optimized and the results show that 56.40 g/100g mass ratio of the cros...

Hydrogels were prepared from cellulose acetate with a degree substitution (DS) 2.5 dissolved in dimethylformamide by esterification crosslinking with Ethylenediaminetetraacetic dianhydride (EDTAD) catalyzed by triethylamine. Subsequent conversion of the unreacted carboxyl groups to sodium carboxylates by the addition of aqueous NaHCO3 was performed to enhance the water affinity of the gels. The...

protein based films used for food packaging despite having numerous benefits like biodegradability and renewability suffer from essential drawbacks of weak mechanical and water vapour barrier properties. in recent years efforts for improving functional properties of such films from various resources, through modifying formulation, molecular crosslinking and promote proteins based composite film...

1A microwave (MW)-assisted crosslinking process to prepare hydrogel-forming microneedle (MN) arrays was evaluated. Conventionally, such MN arrays are prepared using processes that includes a thermal crosslinking step. Polymeric MN arrays were prepared using poly(methyl vinyl ether-alt-maleic acid) crosslinked by reaction with poly(ethylene glycol) over 24 h at 80 °C. Polymeric MN arrays were pr...

In this work, the crosslinking reaction of partially carbonated epoxidized soybean oils with diamines was investigated through an unprecedented combination in situ infrared and Raman spectroscopies, revealing two regimes.

Microbial transglutaminase (mTGase) crosslinking is a useful method for significantly improving the physical functionality of proteins. This study focused on the effect of mTGase modification on the functional properties of yak and cow caseins, including solubility, emulsifying property, water and oil absorption capacity, foaming property, and stability in the presence of Na, Ca, and Mg. The re...

RAFT polymerization was utilized to prepare an amphiphilic block copolymer containing both hydrophilic and hydrophobic segments. The self-assembly behavior of the block copolymer into nano-scale particulate structures was studied in both water and polar organic solvents. Uniform micelle assemblies were stabilized by reaction within the hydrophobic core, which contained pendant azide groups, thr...

The aim of this study was to investigate the effect of high pressure CO(2) on the crosslinking of elastin-based polymers and the characteristics of the fabricated hydrogels. A hydrogel was fabricated by chemically crosslinking alpha-elastin with glutaraldehyde at high pressure CO(2). The effects of pressure, reaction time, and crosslinker concentration on the characteristics of the fabricated h...
