General notes
Prestained Protein Ladder ab116029 is a three-color protein standard with 13 pre-stained proteins covering a wide range molecular weights from 3.5 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).
This product is also sold by Expedeon, an Abcam company as RunBlue™ TriColor Prestained Protein Ladder: NXA6050. This product was previously called Prism Ultra Protein Ladder (3.5 - 245 kDa).
This 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. Do not heat, dilute, add reducing agent before loading.
Key product features:
- Broad range: 3.5-245 kDa
- Ready-to-use: Supplied in a loading buffer for direct loading on gels.
- Easy to identify: Includes green ~25 kDa and red ~75kDa reference bands.
- Sharp bands
- Recommended loading: ~1.5 - 2.5µl

SDS-PAGE - Prestained Protein Ladder – Extra broad molecular weight (5 - 245 kDa) (ab116029)
Gel 1: Tris-Glycine (4-15%) SDS buffer; Gel 2: Bis-Tris (4-12%) MOPS buffer; Gel 3: Bis-Tris (4-12%) MES buffer. Pre-stained molecular weight standards have a differing mobility and as a consequence varying apparent molecular weight when run in distinct SDS-PAGE buffer systems. The variance in pH of alternative buffers affects the charge of the labelled protein standard and its binding capacity for SDS. The apparent molecular weight of this marker has been determined by calibration against an unstained ladder in each electrophoresis condition.
