Overview

eStain is a highly efficient protein PAGE gel staining system, which uses Coomassie Brilliant Blue and a patented protein staining technology developed by Genscript. eStain staining system integrates the traditional three steps of fixing-staining-destaining into one and can stain/destain two protein PAGE gels simultaneously in 10 minutes or less.

eStain works with all types of precast as well as homemade PAGE gels. Compared with the conventional staining methods, gels stained by eStain have crisp blue bands with minimum or no background. eStain also offers superior sensitivity compared to conventional methods and can detect as low as 12.5 ng of protein.

Step 3. Pre-wet a piece of filter paper (provided) with distilled water and place it on top of the gel
Step 4. Close the gel holder
Step 5. Choose a Channel and insert the gel holder into the channel. *Note：Please ensure that the fabric side of the gel holder is facing the user before inserting it into the Channel*
Step 6. Press the corresponding channel to start the program. The channel timer starts to countdown
