TIANGEN Pre-stained Dual Color Protein Marker is a dual color protein molecular weight standard with five pre-stained recombinant proteins covering a range from 18 kDa to 100 kDa. The marker contains two orange reference bands of 28 kDa and 100 kDa, and three blue reference bands of 18 kDa, 45 kDa and 60 kDa.

TIANGEN Pre-stained Dual Color Protein Marker is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western Blot transfer efficiency and for approximately sizing of proteins.
