Blue Prestained Protein Standard, Broad Range (11-250kDa)

Brand: New England Biolabs This product is a direct replacement of NEB# P7706 (Blue Prestained Protein Standard, Broad Range 11-190 kDa). 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
