Example protocol

PREPARATION OF STOCK SOLUTIONS

Unless otherwise noted, all unused stock solutions should be divided into single-use aliquots and stored at -20 °C after preparation. Avoid repeated freeze-thaw cycles

HIS Lite™ Cy5 Tris NTA-Ni Complex Stock Solution

Prepare a 5 to 10 mM stock solution by adding an appropriate amount of DMSO.

Note: Store any unused stock solution at -20 °C. Avoid repeated freeze-thaw cycles and minimize light exposure.

PREPARATION OF WORKING SOLUTION

HIS Lite™ Cy5 Tris NTA-Ni Complex Working Solution

Prepare a 1 to 10 µM HIS Lite™ Cy5 Tris NTA-Ni Complex working solution in PBS.

Note: Ensure that there is sufficient working solution to fully submerge the gel. After use, discard the working solution. Do not reuse.

SAMPLE EXPERIMENTAL PROTOCOL

The following protocol should be used only as a guideline and may require optimization to better suit your specific experimental needs.

Post-run Gel Staining Protocol

Run gels based on your standard protocol.
Place the gel in a suitable container. Fix the gel in the fixing solution for 60 minutes. Note: 40% ethanol + 10% acetic acid can be used as a fixing solution.
Wash the gel twice with the ultra-pure water.
Incubate the gel in the HIS Lite™ Cy5 Tris NTA-Ni Complex working solution for 60 minutes.

Note: Be sure to fully submerge the gel in the working solution.
Remove the working solution and wash the gel twice with PBS.
Proceed to imaging the gel immediately.

For In Vitro Complex Formation

Mix the His-tagged protein solution and the HIS Lite™ Cy5 Tris NTA-Ni Complex working solution at the appropriate concentrations.

Note: Optimization of the HIS Lite™ Cy5 Tris NTA-Ni Complex to the His-tagged protein mix must be performed for better labeling.

Note: 1 to 10 µM of HIS Lite™ Cy5 Tris NTA-Ni Complex can be used as a starting concentration.

Note: The reaction can be performed in a buffer containing 50 mM HEPES/KOH, pH 7.4, 100 mM KCl, 1 mM MgCl2, 2 mM β-mercaptoethanol, 5% glycerol, or a buffer of your choice.
Mix can be incubated for 30 minutes at room temperature or 4 ℃.

Note: Optimization of the incubation time and conditions must be performed for better labeling
Mix can then be subjected to column purification or any other downstream process.

Figure 1. Cy5-Tris NTA compound is used as a sensitive fluorescent probe for detecting polyhistidine-labeled proteins in cells, solution and solid surfaces. In combination with other color tris-NTA compounds (such as #12615 and #12617), it can be used for multicolor analysis of polyhistidine-tagged proteins.
