Product DescriptionHiLyte Fluor* 647 Labeling Kit-NH2 is mainly used for the preparation of red fluorescence-labeled proteins, such as IgG, for immunostaining, and cellular proteins for tracing. NH2-reactive HiLyteFluor 647, a component of this kit, has a succinimidyl group (NHS) that reacts with amino groups on proteins or other molecules (Fig. 1). This kit contains all the reagents necessary for labeling. Each tube of HiLyte Fluor 647 can label up to 200 μg of IgG, conjugating about 4 to 6 HiLyte Fluor 647 molecules per IgG molecule. The labeling process is simple-add the NH2-reactive HiLyte Fluor 647 to IgG solution on a membrane and incubate at 37ºC for 10 minutes. The excess HiLyte Fluor 647 molecules can be removed by a filtration tube. The excitation and emission wavelengths of the HiLyte Fluor 647-labeled IgG are 652 nm and 673 nm, respectively (Fig. 2). *HiLyte Fluor is a trademark of AnaSpec, Inc.

Precaution♦ The molecular weight of the protein to be labeled with this kit should be greater than 50,000.♦ IgG or HiLyte Fluor 647-conjugated IgG is always on the membrane of the filtration tube during the labeling process.♦ If the IgG solution contains other proteins with molecular weights larger than 10,000, such as BSA or gelatin, purify the IgG solution before labeling HiLyte Fluor 647 with this kit. IgG solution can be purified by IgG Purification Kits (not included in this kit).♦ If the IgG solution contains small insoluble materials, centrifuge the solution and use the supernatant for the labeling.

Can I use this kit for other proteins?

Yes, if the molecular weight is greater than 50,000.

Do I have to use a Filtration tube prior to labeling the protein?

If the protein solution does not contain small molecules with an amino group and the concentration of the protein is 10 mg per ml, or about 70 μM, there is no need to use the Filtration tube. Mix 10 μl of the sample solution with 90 μl of Reaction buffer and add 8 μl NH2-reactive HiLyte Fluor 647 (prepared at step 3) to the mixture, and follow the protocol starting at step 4.

How long is the HiLyte Fluor 555-labeled protein stable?

If you store at 4oC, it is stable for over 2 months. For longer storage, add 100% volume of glycerol, aliquot, and store at -20oC. However, please note that stability depends on the protein itself.

What is the minimum amount of IgG that can be labeled by this kit?

The minumum amount of IgG is 10 μg. For less than 20 μg, follow the manual and add 4 μl NH2-reactive HiLyte Fluor 647 instead of 8 μl at step 4.

Can I use this kit to label oligonucleotides or peptides?

No. Oligonucleotides and peptides may be too small to retain on the membrane filter of the Filtration tube.

Dojindo细胞分析细胞活力和细胞毒性测定用于药物筛选和化学物质的细胞毒性测试。Dojindo开发了高度水溶性的四唑盐,称为WST。WST-8是高度稳定的WST,用于Cell Counting Kit-8(CCK-8)。由于WST-8甲maz是水溶性的,因此不会形成晶体。因此,不需要诸如MTT测定的增溶过程。此外,CCK-8的检测灵敏度高于其他四唑盐,例如MTT,XTT,MTS或WST-1。WST检测机制 ß-半乳糖苷酶检测试剂细胞增殖/细胞毒性转染细胞染色细胞内荧光探针细菌染色微生物活力测定干细胞分化SPiDER-ßGal线粒体检测细胞代谢应用产品展示细胞生长检测,药物筛选,比色/荧光检测细胞计数试剂盒-8细胞计数试剂盒8 + 96孔有机硅定向剂细胞计数试剂盒-F细胞毒性LDH检测试剂盒-WST 96孔有机硅定向剂MTT了解检测机制的差异:点击这里细胞周期分析细胞周期测定溶液深红色细胞周期测定溶液蓝色
