b'Prestained protein ladders Prestained protein ladders contain proteins prelabeledPrestained protein ladders can be used to:with various dyes that allow them to be visible without additional staining. Prestained ladders are visible during Monitor protein separation during polyacrylamide electrophoresis, enabling the ability to monitor the progressgel electrophoresisof separation for the range of protein sizes that are most Quickly check visually whether protein transfer has relevant to the particular experiment. Most prestainedoccurred from gel to membrane (prestained protein markers and ladders also remain visible after gel staining orladder should transfer to membrane but should transfer to membranes for detection by western blotting. not be used to determine transfer efficiency; see Good to know notes) Estimate the approximate size of your target protein Low range Low rangekDa kDa~210~78Visible light Near-IR and RGB detectionVisible light Near-IR detection~55~40 ~45~25 ~34~23~15 ~16~10 ~7~5 ~4~2Novex Novex16% Tricine Gel 16% Tricine GelThermo Scientific Spectra Multicolor Low Range Protein Ladder Invitrogen SeeBlue Prestained Protein StandardCat.
