The marker is covalently bound to a blue colour chromaphore to produce a ladder of evenly interspersed bands of uniform intensity. The coloured reference bands are used as visual indicators for the process of gel electrophoresis and the efficiency of the transfer to membranes in the Western Blot. The marker is suitable for the precise identification of the molecular weight of most cellular proteins.

• Easy identification in gels and blots
• Detectable from 2.5 µl
• 2 years stable at - 20 °C
• Vials of 500 µl
