DNA deformations upon environmental changes, e.g., salt and temperature, play crucial roles in many biol. processes and material applications. Here, our magnetic tweezers experiments observed that the increase in NaCl, KCl, or RbCl concentration leads to substantial DNA overwinding. Our simulations and theor. calculation quant. explain the salt-induced twist change through the mechanism: More salt enhances the screening of interstrand electrostatic repulsion and hence reduces DNA diameter, which is transduced to twist increase through twist-diameter coupling. We determined that the coupling constant is 4.5 ± 0.8 kBT/(degrees·nm) for one base pair. The coupling comes from the restraint of the contour length of DNA backbone. On the basis of this coupling constant and diameter-dependent DNA conformational entropy, we predict the temperature dependence of DNA twist Δωbp/ΔT ≈ -0.01 degree/°C, which agrees with our and previous exptl. results. Our anal. suggests that twist-diameter coupling is a common driving force for salt- and temperature-induced DNA twist changes.Rubidiumchloride (cas: 7791-11-9) were involved in the experimental procedure.

The research results were published in《Advanced Optical Materials》 in 2022.Product Details of 7791-11-9 The article conveys some information:

Lead-free halide perovskites and their variants have attracted great attention due to their non-toxicity and good photophys. properties. Here, a series of undoped and antimony-doped all-inorganic, 0D, indium-based perovskite variant nanocrystals (NCs): (Rb_xCs_1-x)₃InCl₆ and (Rb_xCs_1-x)₃InCl₆:Sb (0 ≤ x ≤ 1) NCs, is reported. Among them, Sb-doped NCs exhibit green emission. Mixing Rb-Cs NCs show the higher photoluminescence (PL) quantum efficiency (PLQE) and better stability than unalloyed NCs (x = 0 or 1). The effect of crystal size on PL property of (Rb_0.75Cs_0.25)₃InCl₆:Sb is analyzed in detail. More interestingly, In-based perovskite variant NCs containing coordinated water are successfully synthesized by a two-step method (variable temperature hot injection and saturated steam post treatment). The best PLQE of Sb-doped Cs₂InCl₅(H₂O) NCs reaches 95.5%, which is a new PLQE record for yellow emissive lead-free perovskite and variant NCs. In addition, the emission mechanism is further clarified by temperature-dependent PL and femtosecond transient absorption techniques. To complete the study, the researchers used Rubidiumchloride (cas: 7791-11-9) .

Chen, I-Shan;Eldstrom, Jodene;Fedida, David;Kubo, Yoshihiro published 《A novel ion conducting route besides the central pore in an inherited mutant of G-protein-gated inwardly rectifying K⁺ channel》. The research results were published in《Journal of Physiology (Oxford, United Kingdom)》 in 2022.Quality Control of Rubidiumchloride The article conveys some information:

G-protein-gated inwardly rectifying K⁺ (GIRK; Kir3.x) channels play important physiol. roles in various organs. Some of the disease-associated mutations of GIRK channels are known to induce loss of K⁺ selectivity but their structural changes remain unclear. In this study, we investigated the mechanisms underlying the abnormal ion selectivity of inherited GIRK mutants. By the two-electrode voltage-clamp anal. of GIRK mutants heterologously expressed in Xenopus oocytes, we observed that Kir3.2 G156S permeates Li⁺ better than Rb⁺, while T154del or L173R of Kir3.2 and T158A of Kir3.4 permeate Rb⁺ better than Li⁺, suggesting a unique conformational change in the G156S mutant. Applications of blockers of the selectivity filter (SF) pathway, Ba²⁺ or Tertiapin-Q (TPN-Q), remarkably increased the Li⁺-selectivity of Kir3.2 G156S but did not alter those of the other mutants. In single-channel recordings of Kir3.2 G156S expressed in mouse fibroblasts, two types of events were observed, one attributable to a TPN-Q-sensitive K⁺ current and the second a TPN-Q-resistant Li⁺ current. The results show that a novel Li⁺-permeable and blocker-resistant pathway exists in G156S in addition to the SF pathway. Mutations in the pore helix, S148F and T151A also induced high Li⁺ permeation. Our results demonstrate that the mechanism underlying the loss of K⁺selectivity of Kir3.2 G156S involves formation of a novel ion permeation pathway besides the SF pathway, which allows permeation of various species of cations. And Rubidiumchloride (cas: 7791-11-9) was used in the research process.
