2D Marker is a laboratory grade maker used for molecular biology experiments. The marker is ready to use specifically developed for 2D electrophoresis. 2D electrophoresis is used for separation of protein using their 2 properties first on the basis of their pI and second on the basis of their molecular weight. The 2D marker helps in determining the unknown proteins and separating them efficiently. The marker comes in 0.25ml volume providing 25 lanes volume as a marker. It should be stored at -20-degree Celsius for long term use and activity of an enzyme or 4 degree Celsius for daily usages.
