是的，您可以使用溴化乙锭、SYBR Green I、SYBR Green II和SilverXpress银染试剂盒对TBE凝胶染色。采用溴化乙锭染色时，将胶侵泡在使用超纯水配制的2 µg/mL溴化乙锭溶液中20分钟。染色后使用超纯水连续冲洗3次，每次10分钟，除去未结合染料。在紫外灯下观察条带。
Invitrogen 6% DNA阻滞凝胶包含0.5X TBE。两种凝胶均能用于凝胶阻滞实验；但是，Invitrogen 6% TBE凝胶内的1X TBE有更高的离子环境，可能会影响DNA-蛋白相互作用。Invitrogen 6% DNA阻滞凝胶内的0.5X TBE通常效果更好，因为它在电泳中有较高的片段分离效果而且其离子强度较低，可以促进DNA-蛋白相互作用。
在Invitrogen 10% TBE凝胶上，51 bp的marker条带清晰可见。在Invitrogen 20% TBE凝胶上，18和12 bp的marker条带清晰可见.
我们的TBE凝胶中EDTA浓度是0.06% (质量/体积)。20% TBE凝胶包含4%甘油以获得最大分辨率。所有其它TBE凝胶均仅在凝胶底部9%的范围内含有0.8%甘油，在凝胶的其它部分没有甘油。
可以，对于EB染色，将凝胶在超纯水配制的2 µg/mL EB溶液中浸泡20分钟。接下来使用超纯水进行3次洗涤脱色，每次10分钟。在紫外光下观察条带。
电压：200V恒定电压*
起始电流大约为：10–18 mA/凝胶
结束时电流大约为：4–6 mA/凝胶
电泳时间：大约30–90分钟，取决于凝胶的浓度。当溴酚蓝（深色）示踪染料到达凝胶的底部时电泳结束。
*可以使用最高250 V的电压以减少电泳时间。
请参见下列凝胶技术指标：
凝胶基质：丙烯酰胺/双丙烯酰胺
凝胶厚度：1.0 mm和1.5 mm
凝胶尺寸：8 cm x 8 cm (高x 宽)
胶盒尺寸：10 cm x 10 cm(高x 宽)
TBE凝胶的保质期是8周，应保存于4°C。
Yes, you can stain your TBE gels with ethidium bromide, SYBR Green I, SYBR Green II, and the SilverXpress Silver Staining Kit. For ethidium bromide staining, soak the gel in a 2 µg/mL solution of ethidium bromide in ultrapure water for 20 minutes. Destain by rinsing with three successive 10-minute rinses of ultrapure water. Visualize bands under UV light.
The Invitrogen 6% DNA Retardation Gels contain 0.5X TBE. Both gels will work for gel retardation; however, the 1X TBE in the Invitrogen 6% TBE Gels have a higher ionic environment, which may affect DNA-protein interactions. The 0.5X TBE used in the Invitrogen 6% DNA Retardation Gels usually works better, as it offers good fragment separation in electrophoresis yet has an ionic strength low enough to promote DNA-protein interactions.

On the Invitrogen 10% TBE gels, a 51 bp marker can be clearly seen. On the Invitrogen 20% TBE gel, the 18 and 12 bp markers can be clearly seen.

The EDTA concentration in our TBE gels is 0.06% (w/v). The 20% TBE gels contain 4% glycerol for maximal resolution. All other TBE gels contain 0.8% glycerol in a layer that represents the bottom 9% of the gel. There is no glycerol in the rest of the gel.

Yes, for ethidium bromide staining, soak the gel in a 2 µg/mL solution of ethidium bromide in ultrapure water for 20 minutes. Destain by rinsing with three successive 10-minute rinses of ultrapure water. Visualize bands under UV light

Voltage: 200 V constant*
Approximate current at start: 10-18 mA/gel
Approximate current at end: 4-6 mA/gel
Run time: Approximately 30-90 minutes, dependent on gel percentage. The run is complete when the bromophenol blue (darker) tracking dye reaches the bottom of the gel.
* Voltages up to 250 V may be used to reduce run time.
