Stable for up to 2 years if stored at -20°C and supplied pre-stained in gel loading buffer for direct loading, Cleaver Scientific and BLUE Wide Range recombinant protein markers are perfect for SDS-PAGE applications. Sizes range from 10-245 kDa suitable for accurate molecular weight determination of most cellular proteins.

Each marker is covalently bound to a chromophore to produce a ladder of evenly interspersed bands of uniform intensity. Coloured reference bands serve as visual indicators of electrophoresis run progression and the efficiency of western transfer onto membranes following SDS-PAGE. BLUE Wide Range markers can be detected at volumes as low as 2.5µl per well.
