氨基黑 10B 可用于检测印迹膜上的蛋白质。当转移蛋白量大于 50 ng / 条带时,可在淡蓝色背景上呈现深蓝色条带。在蛋白质内部序列测定中,氨基黑是蛋白质测序与蛋白原位切割最常用的染色剂。
氨基黑 10B 染色液 (0.1%) 主要由氨基黑 10B、弱酸及去离子水等组成,适用于 PVDF 膜、硝酸纤维素膜和尼龙膜。其特点是染色条件温和,可最大程度减少蛋白质洗脱。本产品仅用于科研用途,不可用于临床诊断或其他非科研场景。
自备材料
操作步骤(仅供参考)

2. 试剂开封后请尽快使用,以防影响后续实验效果。
Amido Black 10B can be used to detect proteins on blotting membranes. When the amount of transferred protein exceeds 50 ng per band, dark blue bands appear against a light blue background. For the determination of internal protein sequences, Amido Black is the most commonly used stain for protein sequencing and in situ protein cleavage.
Amido Black 10B Staining Solution (0.1%) is mainly composed of Amido Black 10B, weak acid and deionized water. It is suitable for PVDF membranes, nitrocellulose membranes and nylon membranes. It is characterized by mild staining conditions, which minimize protein elution. This product is for research use only and shall not be used for clinical diagnosis or other non-research purposes.
Materials Required
- Distilled or deionized water, 5% acetic acid
- Shaker
Protocol (For Reference Only)
- Place the blotting membrane in a suitable container and wash with distilled water 3 times, 5 min each.
- Immerse in Amido Black 10B Staining Solution (0.1%) for 1 min or longer.
- Destain in 5% acetic acid twice on a shaker at room temperature, 1 min each.
- Rinse 2–3 times with distilled water, PBS or other appropriate solution, 10 min each.
- Document or photograph the results appropriately.
Precautions
- For your safety and health, please wear lab coat and disposable gloves during operation.
- Please use the reagent promptly after opening to avoid affecting experimental results.
