Products > Optimize Reagents > Optimize – Buffers > Citric acid BIS-TRIS propane Buffer
Citrate BIS-TRIS propane (CBTP) is a buffer system useful across pH 2.5 to 9.5.
Using CBTP one can use a single buffer system to screen pH 2.5 to 9.5 by varying the ratio of Citric acid to BIS-TRIS propane. Although the two buffer reagents are made available separately for convenient, individual replacement, they are designed to be used together, with the supplied CBTP buffer titration table to create a crystallization buffer system covering pH 2.5 to 9.5.

柠檬酸盐 BIS-TRIS 丙烷 (CBTP) 是一种适用于 pH 2.5 至 9.5 的缓冲系统。
使用 CBTP，可以使用单一缓冲系统通过改变柠檬酸与 BIS-TRIS 丙烷的比例来筛选 pH 2.5 至 9.5。 虽然这两种缓冲试剂是分开提供的，以便于单独更换，但它们被设计为一起使用，与提供的 CBTP 缓冲液滴定表一起创建一个涵盖 pH 2.5 至 9.5 的结晶缓冲系统。

Hydroxystilbamidine bis(methanesulfonate), a dye capable of binding to both DNA and RNA, has been found to be a powerful inhibitor of cellular ribonucleases. |
|---|---|
| 体外研究 (In Vitro) |
It is found that the trypanocidal dye Hydroxystilbamidine bis(methanesulfonate) permits the recovery of mRNA after polysome released with Nonidet P-40 (NP-40). Sucrose gradient analysis of detergent-lysed postnuclear supernates is used to analyze the size distribution of NP-40-released polysomes. The heparin gradient shows some polyribosomes, whereas the Hydroxystilbamidine bis(methanesulfonate) gradient shows a remarkably large peak of very heavy polyribosomes. This peak is obtained reproducibly if Hydroxystilbamidine bis(methanesulfonate) is present before the addition of NP-40[1]. MCE has not independently confirmed the accuracy of these methods. They are for reference only. |
| 体内研究 (In Vivo) |
Hydroxystilbamidine bis(methanesulfonate) is an effective suppressor of the plaque-forming cell (PFC) response when given before sheep erythrocytes (SRBC) stimulation. Hydroxystilbamidine bis(methanesulfonate) depresses the plaque response of the treated mice. Fewer PFC are observed in Hydroxystilbamidine bis(methanesulfonate)-treated mice throughout the experiment, but the level of suppression decreases with time. By day 14, the number of PFC observed in both the Hydroxystilbamidine bis(methanesulfonate) treated mice and the control group is essentially at the background level[2]. MCE has not independently confirmed the accuracy of these methods. They are for reference only. |

Silkwork larvae are used in this study. Larvae on the fourth or fifth day of the fifth instar (~4.2 g body weight) are injected with 35 μL of a solution of 10 mg/mL cyclobeximidein H2O. After 5 min, the animals are immobilized in ice, and posterior silk glands are dissected and washed in ice-cold 0.15 M NaCl, 0.015 M Na citrate, 100 μg/mL cycloheximide. Washed glands from two larvae are placed in a homogenizer containing 4.7 mL of 40 mM triethanolamine-HCl, pH 7.5, 0.15 M sucrose, 0.1 M KCI, 3 mM MgCl2, 2 mM reduced glutathione, 10 μg/mL cycloheximide, 750 μg/mL Escherichia coli tRNA, and an appropriate concentration of RNase inhibitor (sodium heparin, 1.5 μg/mL or Hydroxystilbamidine bis(methanesulfonate), 1.5 mM)[1]. MCE has not independently confirmed the accuracy of these methods. They are for reference only. |
|---|---|
| Animal Administration [2] |
Mice (six per group) are given various doses of Hydroxystilbamidine bis(methanesulfonate) (HSB) 3, 2, and 1 day before antigen. Other groups are given Hydroxystilbamidine bis(methanesulfonate) 1 or 2 days after the injection of antigen. Another group of mice receive antigen and Hydroxystilbamidine bis(methanesulfonate) simultaneously. A control group receives only antigen. The antigen dose consists of 2×108 sheep erythrocytes (SRBC). Four days after the injection of SRBC, the mice are sacrificed and spleens are removed and assayed for plaque-forming cell (PFC) by the plaque assay[2]. MCE has not independently confirmed the accuracy of these methods. They are for reference only. |

Bis-ANS dipotassium is a fluorescent probe of hydrophobic protein. Bis-ANS binds to tubulin with a Kd of 2 μM[1]. Bis-ANS dipotassium is a potent biphasic modulator of protein liquid-liquid phase separation (LLPS). Bis-ANS dipotassium promotes LLPS at low concentrations but suppresses LLPS at high concentrations[2]. |
|---|---|
| 体外研究 (In Vitro) |
Bis-ANS is a fluorescent molecule that has been used to probe exposed hydrophobic patches in proteins and to monitor the formation of protein aggregates. Bis-ANS is a bivalent naphthalene sulfonate with aniline moieties. Bis-ANS modulates the liquid-liquid phase separation of TDP-43 low complexity domain (LCD)[2]. MCE has not independently confirmed the accuracy of these methods. They are for reference only. |
