Use a prestained marker to monitor protein separation on SDS-PAGE gels and follow the marker bands during membrane transfer. Choose reference bands around your target protein, not just the widest stated range. The three options below differ in band count, spacing and reference colours. Check the band map for your gel and buffer system: prestaining can affect apparent molecular weight.
Find product documents, request samples and arrange laboratory orders.
Choose a prestained marker by molecular-weight range and gel system.

In this catalogue, both terms refer to the listed prestained molecular-weight markers. Check the complete band map and gel-system guidance for the exact product rather than relying on the name alone.
Section linkThe listed 20347 ladder extends to 300 kDa and starts at 25 kDa. Compare 20350 or 20352 when you also need lower-mass reference bands. Product pages show the full band patterns and manufacturer documents.
Section linkThe PageRuler buying guide compares ranges, band counts and colour references. You can request an evaluation sample of a Yeasen product; sample format and availability are confirmed individually.
