abm | Opti-Protein Ultra Marker | G623

With enhanced performance for high molecular weight proteins, Opti-Protein Ultra Marker consists of 10 pre-stained proteins that resolve into sharp, tight bands covering a wide range of molecular weights from 6.5 to 270 kDa. This protein ladder allows you to monitor protein separation during electrophoresis, estimate molecular weight of the protein of interest, and evaluate western blot transfer efficiency. Proteins are covalently coupled with a blue chromophore except for three reference bands (two orange bands at 30 kDa and 270 kDa and one green band at 52 kDa) when separated on gel.

Suggested load:

Mix gently by pipetting up and down a few time, then directly load 5 μl into well of gel.




6.5 kDa-270 kDa

Shipping Conditions:

Ice Packs

Storage Condition:

Store @ 4°C for 3 months or -20°C for 24 months.


For monitoring protein migration during SDS-PAGE, efficiency of protein transfer onto PVDF or nitrocellulose for Western Blotting and for sizing of proteins on SDS-PAGE and Western Blots
