ClearBand WellTracker is specifically formulated to easily see the wells of the SDS-PAGE gels when loading samples. It is supplied as 100x concentrate and added in stacking gel to better visualize the wells of the gel.
The special dye within ClearBand WellTracker migrates with bromophenol blue and does not interfere with the samples when they run in the gel. It is totally inert and does not affect the transfer efficiency of proteins from gel to the membrane.
