产品信息

The Unstained Protein Standard, Broad Range is a mixture of highly pure, recombinant proteins that resolves into 13 sharp bands from 10-200 kDa when electrophoresed and stained with Coomassie Brilliant Blue R-250 (1,2) or other commercially available, ready-to-use protein stains. This standard allows accurate molecular weight determination when performing SDS-PAGE analysis.

    1. To ensure uniform mobility, load an equal volume of 1X Reducing SDS Loading Buffer into any unused wells.
    2. To maximize shelf life, store at -20°C. Guaranteed stable for 2 years when properly stored.
    3. It is not necessary to pre-heat the unstained protein standard prior to loading on a gel.
    4. Recommended mini-gel load: 3 μl.
    5. Apparent molecular weight values for prestained proteins can be different when run on different gel types and percentages.
