ProLite™ His-Tag Protein Gel Staining Kit *Green Fluorescence*
The polyhistidine tag (His-Tag) is widely used for protein purification, detection, and immobilization. The ProLite™ His-Tag Protein Gel Staining Kit provides a fast, sensitive, and highly specific fluorescent stain for visualizing His-tagged fusion proteins directly in a polyacrylamide gel following electrophoresis. This kit requires very little hands-on time, allowing for rapid protein expression screening in a variety of gel types using an imaging equipment with a standard FITC filter. It detects nanogram of His-tagged proteins directly in gels, thus eliminating the additional western blotting step. AAT Bioquest offers the largest selection of the His-Tag detection and purification products.
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.
ProLite™ His-Tag Protein Gel Stain stock solution
Prepare a ProLite™ His-Tag Protein Gel Stain stock solution by adding 60 µL of DMSO to a vial of ProLite™ His-Tag Protein Gel Stain. Note: 1 vial of stock solution is suitable for two gels. Store any unused stock solution at -20 °C.PREPARATION OF WORKING SOLUTION
ProLite™ His Tag Protein Gel Stain working solution
Prepare a ProLite™ His-Tag Protein Gel Stain working solution by adding 30 µL of ProLite™ His-Tag Protein Gel Stain stock solution to 30 mL of PBS. Note: Make enough working solution that the gel is completely immersed in the working solution. Do not reuse the working solution.SAMPLE EXPERIMENTAL PROTOCOL
The following protocol should be used as a guideline.
Post-staining protocol
- Run gels based on your standard protocol.
- Place the gel in a suitable container, and fix the gel in a fixing solution for 60 minutes.
Note: 40% ethanol + 10% acetic acid can be used as a fixing solution.
-
Wash the gel twice with ultra-pure water.
- Incubate the gel in the ProLite™ His-Tag Protein Gel Stain working solution for 60 minutes. Be sure the gel is immersed in the working solution.
- Remove the working solution and wash the gel twice with PBS.
- Proceed to imaging the gel immediately.
