MOPS-SDS is ideal for use as a running buffer when resolving medium to large proteins with SDS-PAGE. Gels run with MOPS-SDS buffer run slower than those using MES-SDS buffer. The final concentration of a 1X working solution is 50mM Tris, 50mM MOPS, 0.1% SDS and 1mM EDTA. Premeasured pouches make 1 liter of 1X buffer solution Just empty the pouch into water and stir - no diluting of stock solutions No pH adjustment necessary Quality and consistency guaranteed Nuclease and protease free Long shelf life
