This product was previously called Prism Ultra Protein Ladder (10-245 kDa).
ab116028 is a three-color protein standard with 12 pre-stained proteins covering a wide range of molecular weights from 10 to 245 kDa. Proteins are covalently coupled with a blue chromophore except for two reference bands (one green and one red band at 25 kDa and 75 kDa respectively) when separated on SDS-PAGE(Tris-glycine buffer).
ab116028 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.

Storage: Stable for up to 3 months at 4°C. For long term storage, store at -20°C.
Our Abpromise guarantee covers the use of ab116028 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|SDS-PAGE||Use at an assay dependent concentration. 3 µl or 5 µl per loading for clear visualization during electrophoresis on 15-well or 10-well mini-gel, respectively.|
|WB||Use at an assay dependent concentration. ~1.5-2.5 µl per well for general Western transferring. Apply more for thicker (> 1.5 mm) or larger gel.|
