High-mobility group box protein 1 (HMGB1) is a chromatin-associated nonhistone protein widely distributed in the nucleus of eukaryotic cells. It is transported extracellularly as a proinflammatory mediator or late warning protein to induce immune and inflammatory reactions upon stimuli such as microbial infection. Here, we have found that HMGB1 directly interacts with bacterial DNA analogue CpG-A in the extracellular environment to undergo liquid-liquid phase separation (LLPS) via its positively charged DNA-binding domain.

This study focuses on developing an analytical method to efficiently extract and concentrate several adipate and phthalate plasticizers that can migrate from plastic packaging into various wound disinfectants. The study employed an approach that combined dispersive micro solid phase extraction with dispersive liquid-liquid microextraction using ZIF-4 as an adsorbent. The adsorbent was thoroughly characterized to understand its properties.

Phase separation has been discovered as a new form of regulation in innate immunity. Here, we found that IL6Ra in teleost fish has a unique intrinsic disordered region (IDR) in its amino acid sequence, distinguishing it from the IL6Ra of higher vertebrates. This unique feature endows IL6Ra with the ability to undergo liquid-liquid phase separation, enabling the organism to swiftly initiate an immune response at the early stages of viral infection.

A method for determination of ten kinds of sweeteners in soybean products by multi-plug filtration cleanup (-PFC) combined with ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was established. The sample was extracted with acetonitrile (containing 1% formic acid), degreased by using -hexane liquid-liquid extraction and purified by solid phase extraction using an -PFC column (Oasis PRiME HLB). The analytes were separated by using a Waters ACQUITY UPLC® BEH C (2.

Spontaneous chiral symmetry breaking remains a fascination in chemistry, biology, materials science, and even astronomy. Chiral symmetry breaking usually requires intrinsic molecular chirality or extrinsic chiral sources but remains rare in nonchiral systems. Here, we reveal a ubiquitous, entropy-driven chiral symmetry breaking mechanism observed in 22 out of 35 conjugated polymers in the absence of any chiral source─a phenomenon overlooked for decades.
