Prometheus® ProSignal® Full-Range Prestained Protein Ladder is a three-color protein standard with 11 pre-stained proteins covering a wide range molecular weights from 10 to 250 kD. Proteins are covalently coupled with a blue chromophore except for two reference bands (one green and one red band at 25 kD and 70 kD respectively) when separated on 4-20% gradient gel.
The Prestained Protein Ladder is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western transfer efficiency on membranes (PVDF, nylon, or nitrocellulose) and for approximating the size of proteins. The ladder is supplied in gel loading buffer and is ready to use.

What are the protein concentrations of each band on the ladder?
Each band contains approximately 2 micrograms of protein. To accurately quantify the protein, users should utilize a standard method, such as a BSA (Bovine Serum Albumin) curve, and measure the optical density (OD).
