Alkali Scientific Full Range Prestained Protein Ladder, Tricolor (10 245kDa), 500uL
This three color protein standard offers 12 pre stained proteins ranging from 10 to 245 kDa, clearly visible on gels and transfer membranes (but not on film or imaged blots). It is supplied at a high concentration of 3–3.5 mg/ml, delivering 2–3 times more product than many leading brands and sufficient for 100 to 150+ applications under recommended conditions. Reference bands: Includes two distinct markers—a green band at 25 kDa and a red band at 75 kDa—when separated on SDS PAGE (Tris glycine buffer). Applications: Ideal for monitoring protein separation during SDS PAGE, verifying Western transfer efficiency, and estimating protein s. Loading volumes: Use 3 µl per lane for 15 well mini gels or 5 µl per lane for 10 well mini gels. For Western transfers, 1.5–2.5 µl per lane is sufficient, with larger volumes recommended for thicker (>1.5 mm) or larger gels. Stability: Stable up to 2 weeks at 25 °C, up to 3 months at 4 °C, and long term at –20 °C.
Genetex Inc Trident Prestained Protein Ladder (High Range)
The Prestained Protein Ladder is a three-color protein standard with 12 pre-stained proteins covering a wide range 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). 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.
