Western Blot Marker I is a prestained exposure protein marker, it consists of a mixture of eight high-purity recombinant protein and two pre-stained recombinant proteins, which is convenient for monitoring of electrophoresis and transfer efficiency. It is suitable as a protein molecular weight standard for SDS-PAGE and Western Blot. The bands display in Tris-Glycine gel range from 12-154 kDa (~12, ~22, ~28, ~38, ~50, ~62, ~70, ~78, ~113, ~154 kDa), of which 70 kDa is an orange-red prestained band, 12 kDa is a blue band. The eight recombinant protein bands are able to bind to almost all kinds of antibodies in order to show up together with target protein during imaging. Storage and Handling Conditions Storage at -20°C;Valid for 12 months.
