Pre-stained Protein Ladder RA10070
10 – 180 kDa · 10 bands · Ready-to-use
RA10070 is a ready-to-use, three-color pre-stained protein molecular weight standard containing 10 highly purified recombinant proteins (10–180 kDa). The 70 kDa and 25 kDa bands are orange reference bands, the 10 kDa band is green, and the remaining bands are blue. This product is designed for SDS-PAGE and Western blotting, allowing direct visualization of band migration during electrophoresis and clear band visibility after transfer without any additional processing.
Features
Ready-to-use — No boiling, dilution, or reducing agents required; load directly.
Three-color pre-stained — Orange/green/blue bands for rapid molecular weight identification.
High purity — Recombinant proteins with no interfering bands and clean background.
Excellent stability — Stable for 36 months at -20°C; room temperature shipping stable.
His-tag free — Avoids non-specific binding.
Lot-to-lot consistency — Rigorous QC ensures consistent band migration.
