双色SDS-PAGE蛋白上样缓冲液 (5×) 是阿拉丁自主研发的一款更加安全无气味、含有蓝色和红色两种染料、5倍浓缩的改良型蛋白上样缓冲液。其中的蓝色染料的迁移速度与溴酚蓝一致,红色染料的迁移速度稍快于蓝色染料,在胶浓度高于12%时,红色染料的迁移速度微慢于蓝色染料。红色染料可随蛋白转印到PVDF或NC膜上,可以用于转膜后的泳道示踪。本产品从-20°C取出后可快速融化,不粘稠且节省时间;使用无味、更稳定的新型还原剂代替了DTT和β-巯基乙醇。适用于SDS-PAGE蛋白样品的上样操作,与常规SDS-PAGE蛋白上样缓冲液的使用效果一致,未观察到有任何显著差异。
使用说明:
1.在室温(10~30°C)融化完全,并混匀。注:如需要更快速使用,可置于37°C水浴或金属浴中融化,但尽量减少融化后水浴或金属浴放置时间。
2.每20μl蛋白样品加入5μl的上样缓冲液(5倍稀释),混匀。注:如果蛋白样品浓度过高,可以用双蒸水稀释后再加入上样缓冲液。
3.将上述混合物放入100°C水浴加热5-10分钟,使蛋白变性。
4.冷却至室温后,10000-14000rpm离心2-5分钟,取上清直接上样即可。
5.通常电泳至溴酚蓝到达胶的底端附近1cm处即可停止电泳。
注意事项:
1.无气味款和含DTT款SDS-PAGE蛋白上样缓冲液因为含有的还原剂不同,个别蛋白的电泳结果可能会有差异。
2.本产品含有变性剂,不适用于Native-PAGE。
3.本产品必须完全融化混匀后再使用。
4.为了您的安全和健康,请穿实验服和佩戴一次性手套。
Dual Color SDS-PAGE Protein Sample Loading Buffer (5×) is an independently developed product by Aladdin. It is an improved 5-fold concentrated protein loading buffer that is safer and odor-free, containing two dyes: blue and red. The migration rate of the blue dye matches that of bromophenol blue, while the red dye migrates slightly faster than the blue dye. For gels with concentration higher than 12%, the red dye migrates a little slower than the blue dye. The red dye can be transferred together with proteins onto PVDF or NC membranes, which allows lane tracing after membrane transfer. This product thaws rapidly after removal from -20°C storage. It is non-viscous and saves operation time. A new odorless and more stable reducing agent is adopted to replace DTT and β-mercaptoethanol. It is suitable for sample loading in SDS-PAGE. Its performance is consistent with conventional SDS-PAGE protein loading buffer, with no significant differences observed.
Instructions for Use:
1. Thaw completely at room temperature (10~30°C) and mix well. Note: For faster preparation, thaw in a 37°C water bath or metal bath. Minimize the incubation time in water bath or metal bath after thawing.
2. Add 5 μL loading buffer to every 20 μL protein sample (5-fold dilution), and mix thoroughly. Note: If the protein sample is overly concentrated, dilute the sample with double-distilled water before adding loading buffer.
3. Heat the mixture in a 100°C water bath for 5–10 min to denature proteins.
4. Cool down to room temperature, centrifuge at 10000–14000 rpm for 2–5 min, then take the supernatant for direct loading.
5. Normally stop electrophoresis when bromophenol blue migrates to approximately 1 cm above the bottom of the gel.
Precautions:
1. Due to different reducing agents, the odor-free version and DTT-containing version of SDS-PAGE protein loading buffer may yield different electrophoresis results for individual proteins.
2. This product contains denaturants and is not applicable to Native-PAGE.
3. The product must be fully thawed and homogenized prior to use.
4. For your safety and health, wear a lab coat and disposable gloves.
