Step-view™ 20kD marker is a mixture of 8 recombinant purified protein whose molecular weights are well-adjusted. Step-view™ 20kD protein molecular weight standard is available in a ready-to-use formula (no need to boil before use), and is suitable for sizing proteins between 20,000 and 140,000 Da by SDS-PAGE.

- 20 kDa size increment (20 – 140 kDa, easy size estimation)
- Highly purified and blended 8 recombinant proteins
- His-tag sequence in the proteins enables detection on western blots by anti-6x His antibody
