Product details:
Unstained Protein Ladder ab234618 contains 12 unstained recombinant proteins covering a wide range of molecular weights from 10-200 kDa.
This unstained protein ladder is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis and verifying Western transfer efficiency on membranes (PVDF, nylon, or nitrocellulose) and for approximating the size of proteins.
Key features include:
Broad range:
10-200 kDa
Ready-to-use:
Supplied in a loading buffer for direct loading on gels.
Easily identified:
The proteins resolve into clearly identifiable bands when separated on the SDS-PAGE gel (MES buffer), with the intensified 25 kDa and 85 kDa protein bands serving as the two reference bands.
5 μl per loading for clear visualization during electrophoresis on 15-well or 10-well mini-gel and for Western transferring.
