GangNam-STAIN™ Prestained Protein Ladder is a protein marker that can identify the protein size during protein electrophoresis with 12 bands between 10~245 kDa. It is specially efficient to use by two reference bands (Green:25 kDa, Red:75 kDa) and possible to use directly without pre-treatment such as buffer dilution. GangNam-Stain™ Prestained Protein Ladder is very suitable for protein separation from SDS-PAGE, confirmation of Western blot transfer efficiency, CBB staining and silver staining.
