Prime-Step™ Prestained Broad Range Protein Ladder

The Prime-Step™ Prestained Broad Range Protein Ladder is a three-color protein standard with 10 prestained chromophore-conjugated recombinant proteins covering a wide range of molecular weights, from 6.5 to 270 kDa. It is ideal for monitoring protein separation during SDS-PAGE, confirming WB transfer on membranes, and estimating protein sizes.
