Application


  • 含热不稳定物质的共晶系统的非理想性评估。:该研究探索了利用氯化四甲铵来研究共晶混合物的非非理想性(non-ideal behavior)行为,有助于更好地进行材料科学和工程领域的热管理(Minceva M et al., 2023)。

  • 作为特异腐质霉角质酶热稳定剂的天然低共熔溶剂。: 该研究考察了四甲基氯化铵基低共熔溶剂如何稳定酶,增进了其在生物技术工艺中的实际应用(Sisti L et al., 2023)。

The Fbw7 tumor suppressor targets a broad network of proteins for ubiquitylation. Here we show critical functions for Fbw7 dimerization in regulating the specificity and robustness of degradation. Dimerization enables Fbw7 to target substrates through concerted binding to two suboptimal

A simple and low-cost colorimetric assay utilizing ferrofluidic nanoparticulate probes (FNPs) and a ligase for single-nucleotide polymorphism genotyping is described. Excellent sensitivity and selectivity were accomplished through the engagement of the FNPs and a ligase chain reaction.
