Bromothymol Blue is a pH indicator.

体外研究
(In Vitro)

A first characterization and comparison is done by developing an easy and direct measurement method based on a pH indicator system using Bromothymol Blue (BTB) as the indicator and potassium phosphate as the buffer. A pH-shift assay is developed on the basis of BTB as the pH indicator and potassium phosphate as the buffer component[1]. Three pH indicators are tested for the direct determination of 2- 2-keto-L-gulonic acid (2-KLG) production on a plate. The results show that Bromothymol Blue is superior to the other two indicators in terms of the obvious color change and a suitable pH range (blue to yellow at pH 6.5-7.5). Upon the addition of a Bromothymol Blue solution (0.1%, w/v) to an agar plate, zones surrounding colonies of K. vulgare 07 mutants change their color from blue to yellow because K. vulgare 07 mutants release 2-KLG on agar plates, thereby acidifying surrounding areas around colonies[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Kinase Assay
[1]

For all three enzymes, an expression in the 96-deep well scale is performed. Therefore, electrocompetent E. coli ArcticExpress(DE3) cells are transformed with the corresponding plasmid. Single clones are picked using the CP7200 Colony Picker and transferred to 96-deep well plates filled with 1.2 mL autoinduction media by a MicroFlo Select dispenser. After incubation (36 h, 37°C at 1,000 rpm), further processing is done manually. First, 100 μL of cell culture is transferred into a 96-well plate (U-shaped bottom) and harvested by centrifugation (4,570 rpm, 10 min at RT) while the supernatant is discarded. The frozen pellets (1 h at -20°C) are thawed at room temperature for one hour to improve cell lysis. Lysis is continued by the addition of 30 μL lysis buffer (3 h, 1,000 rpm, 37°C) containing 2 mM KPi, pH 7.0, 2 mM MgCl2, 10 μg/mL DNaseI, 100 μg/mL lysozyme. Next, 120 μL buffer (2 mM KPi, pH 7.0) is added followed by centrifugation (3,000 rpm, 15 min at RT). For the photometric measurement, 20 μL of the crude extract is transferred to a 96-well plate (F-shaped bottom) and the reaction is started by adding 180 μL master mix to give a final volume of 200 μL (2.5 mM KPi, pH 7.0, 2 mM MgCl2, 25 μg/mL BTB and 5 mM keto-deoxy-D-glucarate). The measurements are carried out for 60 min at 2-min intervals. Depending on the enzyme, different time windows are used for the activity calculation[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

生物活性

Isosulfan blue is a blue dye for the identification of lymph vessels during lymphangiography. Isosulfan blueis is used during sentinel lymph node biopsies in breast cancer. Isosulfan blue is possible to have an allergic reaction during breast cancer operations[1][2].

体外研究
(In Vitro)

Isosulfan blue can rapidly uptake into lymph tissue with little diffusion to other surrounding tissues[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

可清洗去除的细胞染色探针

CytoSeeing<Reversible Cytoplasm Blue>

CytoSeeing是一种新型细胞染色试剂,只需添加到培养基即可迅速对细胞质进行染色。荧光观察细胞质后,只需更换不含CytoSeeing的培养基,便可轻松去除细胞内的荧光染色。

◆关于CytoSeeing

已知细胞核与细胞质的形态变化与细胞分化、功能、信号反应相关。传统的细胞质染色探针,主要作为细胞示踪剂使用,一旦摄入细胞,即使去除培养基中的试剂也会残留在细胞内。随后,细胞内的染色试剂随着细胞分裂的过程逐渐褪色,通常在3~6代左右便会消失。但是如果染色试剂残留在细胞内的话,实时成像观察细胞质与细胞核的形态后,难以立即使用其他探针进行成像。

不同于传统试剂,CytoSeeing是一种仅对细胞质进行染色且可清洗的细胞染色试剂。

◆特点


● 只需添加到培养基即可对细胞质进行染色。

● 染细胞质,但不会进入细胞核内。可以通过细胞核的边界对其进行形态学上的观察。例如,适用于活细胞中血细胞的细胞核形态观察。

● 可使用DAPI滤光片进行检测,且能够与GFR和RFP等绿色或红色荧光物质同时使用。

● CytoSeeing的可视化不会影响细胞功能。

● 通过培养基或PBS清洗摄入细胞的CytoSeeing,可从细胞中去除CytoSeeing。

● 去除CytoSeeing后,可直接用于其他检测。

● 可用于贴壁细胞与悬浮细胞。

在A549细胞中CytoSeeing的时间依赖性摄取和分布


a)添加CytoSeeing(10 μM)至细胞中,并孵育。仅需9 min,CytoSeeing已被充分摄入到细胞内。

b)使用CytoSeeing(10 μM)染色细胞后,更换到不含CytoSeeing的培养基中孵育。仅需30 min CytoSeeing便脱离细胞。
