镍柱纯化是为了纯化带有His标签的重组蛋白而设计,它具有高度的亲和力和选择性。反复使用后其镍离子会不可避免的逐渐流失,结合效率会有所下降,需用简单再生后才可再使用。当镍柱介质的颜色由浅蓝色变成灰褐色或白色时,则镍离子已经从柱子中丢失,镍柱介质需彻底再生后才能使用。为此开发了镍柱原位再生试剂,它具有下列特点:
1. 即开即用,不用单独准备各种溶液。
2. 原位再生,直接在亲和层析柱中进行所有再生处理,免去繁琐的装柱步骤。
3. 操作步骤简单,半小时即可完成。
4. 适用于各种含镍介质(包括Ni-NTA或Ni-IDA)。
5. 本产品可以再生已经装有1 mL镍柱介质的层析柱20次。
6. 本产品仅供科研使用。
使用方法
镍柱介质对His标记蛋白结合降低(蓝色越来越淡)时需要按下列步骤再生,如果是污染了其他蛋白和杂质,则需要另购镍柱原位清洗试剂盒。
1. 用10倍介质体积的溶液A洗涤镍柱。对1 mL的镍柱介质(可能是装在 6-7 mL的层析柱中),需要用10 mL溶液A洗涤。
2. 用10-20倍介质体积的自备去离子水洗涤镍柱。对于1 mL的镍柱介质,需要10 mL去离子水。
3. 用5倍介质体积的溶液B洗涤镍柱,镍柱的颜色将变成蓝绿色。
4. 用10倍介质体积的自备去离子水洗涤镍柱后即可使用。如果需要保存镍柱,则封住层析柱的下端出口,加入20%乙醇溶液覆盖镍柱介质,再盖上层析柱的上端口即可4℃长期保存。
Nickel column purification is designed for the purification of recombinant proteins tagged with six histidine residues (basic amino acids), featuring high affinity and excellent selectivity. When purifying the same target protein, the nickel column medium can be reused 3 to 5 times without regeneration. After repeated use, bound nickel ions will gradually leach out inevitably, leading to decreased binding capacity after 3-5 runs, thus simple regeneration is required for further application. When the color of nickel column medium changes from light blue to grayish brown or pure white, it indicates severe loss of nickel ions, and the medium must be fully regenerated before reuse. This nickel column in-situ recharge kit is developed to solve this problem, with the following advantages:
1. Achieve thorough in-situ cleaning and regeneration of nickel column medium, effectively restore its binding activity.
2. Ready-to-use formula, no extra buffer preparation required.
3. Complete all regeneration procedures directly inside the affinity column, eliminating tedious column packing operations.
4. Simple operation procedures, and the whole process can be finished within half an hour.
5. Compatible with all common nickel-charged media including Ni-NTA and Ni-IDA resins.
6. Sufficient reagents for full regeneration treatment of 1 mL nickel column medium for 20 times.
7. For research use only.
Instruction for use
Perform regeneration timely when the His-tag protein binding capacity declines and the light blue color of resin fades obviously. For columns severely contaminated with miscellaneous proteins and impurities, please use dedicated nickel column in-situ cleaning kit separately.
1. Wash the nickel column with Solution A at 10 times the volume of resin. For 1 mL nickel resin packed in 6-7 mL chromatography column, use 10 mL Solution A for washing.
2. Rinse the column with self-prepared deionized water at 10 times resin volume; 10 mL deionized water is needed for 1 mL resin.
3. Flush the column with Solution B at 5 times resin volume, and the resin will recover to light blue-green color.
4. Rinse again with 10 times volume of self-prepared deionized water, then the column is ready for subsequent purification.For long-term storage, seal the column outlet, cover the resin with 50% ethanol solution, seal the upper port, and store at 2-8℃.
