This product is a direct replacement of NEB# P7706 (Blue Prestained Protein Standard, Broad Range 11-190 kDa).
Product Introduction
The Blue Prestained Protein Standard, Broad Range is a mixture of highly pure, recombinant, prestained proteins, covalently coupled with a blue chromophore, that resolves into 11 sharp bands when electrophoresed.
- Allows approximate molecular weight determination when performing SDS-PAGE analysis.
- Applications include verification of Western transfer efficiency on membranes and fluorescent imaging of SDS-PAGE.
- Direct loading, additional loading buffer and heat incubation not required
- Recombinant proteins with no detectable protease contaminating activities
- Optimal stability for up to 24 months

Product Information
Description
The Blue Prestained Protein Standard, Broad Range is a mixture of highly pure, recombinant, prestained proteins, covalently coupled with a blue chromophore, that resolves into 11 sharp bands when electrophoresed. The Blue Protein Standard is designed for observing protein separation during SDS-PAGE, verification of western transfer efficiency on membranes and for approximating the size of proteins (1-2). It may also be used in fluorescent imaging of SDS-PAGE.

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